What to do if the Tomahawk alarm does not go off from the key fob?

There was a need to replace the key fob for the TOMAHAWK TW-9010 alarm system. There were no problems with the purchase, the problems began when programming the key fobs. I did it according to the instructions: 1. Turn on the ignition 2. Press and hold the OVERRIDE button until the siren emits 4 “CHIRPS”, hold for about 6 seconds 3. Press and hold the buttons on which the trunk and the crossed out siren are drawn. until you hear the “CHIRPS” of the siren confirming the programming of the new key fob (1 chirp for the first, two chirps for the second, etc. up to 4) 4. Turn off the ignition. The parking lights will flash 5 times to confirm exit from programming. It is necessary to rewrite all key fobs, otherwise the old ones (which were working) will stop working. But there was no result, the signal blinked 5 times and no chirps. I spent 2 days and no results. I scoured the Internet and came across this information on the website: Doesn’t see the ignition, try turning the ignition on and off several times and try. If this does not work, connect the ignition wire to a constant plus during programming. Without hesitation, I opened the installation instructions and did the following (so as not to pull the wire from the battery) 1 Find

The Tomahawk anti-theft system has gained popularity among car owners due to its reliability, low price and the ability to be serviced in many service centers. But during operation, problems in the operation of the security system are revealed. One of the most common is that the Tomahawk alarm does not respond to the key fob. You press buttons and nothing happens. There are several reasons why the key fob does not work:

• dead battery. Remove the battery. Check the voltage with a multimeter (15 percent less than the nominal value is acceptable). Install a new battery and test how the remote control works;
• the presence of external interference that disrupts the connection between the pager and the system. Park your car somewhere else;
• key fob desynchronization. Re-register the switches in the system memory;
• transmitter failure. Contact the professionals;
• Broken cable wires or poor contact. Ring each wire, inspect the places where they are connected to the terminal block.

No feedback: what to do

The Tomahawk line includes models.

1. With autostart: Q9 Dialog, 9.3, 9.5, 9.7, 9.9, 10.1, 9.3-24, G-9000, SL-950, TZ-9010, TZ-9030, Z-5.
2. Single sided: CL-550.
3. Double sided: 7.1, 7.2, 8.1.

But, as always happens, at the most inopportune moment the alarm remote control stops responding to your actions: the car does not open, the display does not work, the light does not blink. Let's look at the most common reasons for poor functioning of the key fob and how to eliminate them.

1. The battery has exhausted its resource. Replace it with a new one.
2. The remote control has fallen off. Reattach the key fob.
3. Poor contact on the switch circuit board. Open the case, carefully inspect the contacts of the chip and display. Carry out repairs yourself or take the pager to a service center.
4. Transmitter failure. Contact your service center.
5. Damage to the main control unit cable. Carry out the repairs yourself or go to an installer.
6. External interference. Move the car to a new location.

Why do you need Valet mode?

The Valet function of the anti-theft complex Tomahawk CL 550, LR 1010 LC, Q9, G 9000, LR 950 LE, S 700 disables all its main features and is used when carrying out repair work on the vehicle.

To activate the mode.

1. Disarm the car.
2. Turn on the ignition.
3. Press key 2 on the key fob for two seconds.
4. The siren will sound ten times.

You can turn off the “Valet” mode like this.

1. Activate the ignition.
2. Hold the pager button 2 for two seconds.
3. The siren will sound ten times and the LED will go out.

Tomahawk alarm system: poor signal reception from the remote control

Tomahawk has established itself as an inexpensive and reliable anti-theft system. But it also has glitches: the signaling system glitches, flashes, and emits short beeps. What are the reasons?

1. Battery low. Insert a new battery and check the operation of the remote control.
2. The remote control is out of sync. Re-register it following the instruction manual.
3. Exposure to external interference. Move to another location and check your pager.
4. The remote control is broken. Repair the key fob yourself, contact a service center or buy a new one.
5. The control unit has failed. Go to an electrician.

Error: LED blinks 2, 3, 4 times and that’s it

It turned out to be a glitch in the signaling - the LED was blinking, the engine was blocked from starting. One of the reasons is the incorrect operation of the door, hood, and trunk switches. Clean contacts or replace switches. Test the alarm.

Another reason may be the incorrect location of the car engine temperature sensor. Reinstall the sensor according to the instruction manual.

Tomahawk 9010 does not respond to the key fob: reasons

There are situations when the remote control refuses to work for some reason, the TW 9010 does not work, it beeps once, what is this? Don't panic right away. There are several main reasons, knowing them, you can correct a difficult situation:

• The battery has failed. Replace it with another one;
• wear of the anti-theft system. Go to a service center;
• violations in synchronization of the remote control with the signaling system. Re-enter the pager into the security system memory;
• switch failure. Repair it yourself or contact a specialist.

Having correctly carried out the diagnosis, you can quickly restore the key fob and continue to use it.

Causes

First, let's figure out why autostart does not work on the Tomahawk alarm system. There may be several reasons for this:

1. The operating conditions of the automatic engine start are violated.
2. The car owner used the wrong button combinations.
3. Lack of limit switch contacts.
4. Problems with the crawler.
5. Incorrect location of the crawler chip relative to the receiving antenna.
6. Other problems.

Above are the main reasons why autostart on the Tomahawk 9010 alarm system does not work. Eliminating them allows you to restore the functionality of the device without going to a service station and wasting money.

Tomahawk 9010 does not start with key fob: SP error

The autostart stopped working, the engine starts, but immediately stalls. Autostart is activated in three modes: by tachometer, by oil pressure and by generator voltage. If the engine does not start and the control panel receives a failure, first check the wiring and limit switches. Everything is fine - reset all settings:

1. Turn off the ignition.
2. Press the Override button nine times.
3. Turn on the ignition and click “Override” once.
4. At the first signal, press the button with the image of a closed lock.
5. Turn off the ignition. All settings returned to their original factory settings.

Functions performed

The Tomahawk alarm system has the following features:

• feedback providing information about the state of the system;
• search for a stolen car;
• automatic engine start when the temperature drops to a certain level;
• motor blocking;
• safe driving;
• quiet mode;
• immobilizer;
• door lock programming function;
• opening the trunk by pressing one button;
• anti-scanner;
• additional control channels.

Tomahawk X5 does not respond to buttons

There are often cases when the X5 alarm key fob does not see the car. The security does not turn on or off. This does not depend on the make of the car (Priora, Kalina, Ford, etc.). Why the security system does not respond to the key fob buttons:

• The battery in the remote control is dead. Change to another;
• The switch is broken. Repair it yourself or give it to specialists;
• failure of the pager and the system to work together. Register the keychain;
• damage to the control unit cable. Solder the wires yourself or contact an auto electrician;
• control unit failure. Go to a service center.

Pager 9020 does not lock or open doors

Your vehicle is not armed. Doors do not open or close. What is the reason? One of the most common breakdowns of a security system is the failure of the remote control. There are several reasons for the key fob to malfunction.

1. The battery has exhausted its resource. Replace with a new one.
2. Poor contact of the chip or printed circuit board located inside the key fob body. Disassemble the switch. Carefully inspect the circuit board and chip. If you cannot repair it yourself, contact a specialist.
3. The key fob has “fallen off” from the system. Re-register the remote control in the Tomahawk 9020 memory. Before doing this, carefully read the instructions.

Emergency disarming

There are times when the car is perfectly armed with the 9010 system, but then opening it is a problem. The key fob displays “open” as always, but the central locking is still closed. You need to listen and understand whether the central locking works. If everything is in working order, then it is necessary to inspect all the fuses.

This often happens when the adapter is burned out. You can find it on the locking relay. In cold weather they become brittle and break. If everything is in order with the adapter, then you need to check the drive at the central locking; you can find it at the driver's door. The reason for the violation is the rod that goes from the lock on the front door to the central lock of the car alarm. Everything can be fixed and fixed.

What if the tomahawk alarm does not go off from the key fob?

Many motorists have encountered a problem at least once during the use of modern alarm systems - the car does not open when the key fob button is pressed. This can happen near home, work, or at the most inopportune moment when you urgently need to go. The reasons can be different: from a dead battery to failure of the main alarm unit. Reasons for loss of connection ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more» Contents

• 4 Emergency disarming on some Tomahawk alarms

Tomahawk alarms have been in demand among car owners for more than 10 years.

Activate only the functions you need

One of the most useful features of the Tomahawk is autostart, which brings even more comfort when operating the machine. Follow these simple steps to activate this feature.

1. Park.
2. Put the gear in neutral and apply the handbrake.
3. Press the autoplay key and an alert tone should sound.
4. Remove the ignition key. Leave the salon and close all doors.

Car alarm keychain. what to do if the key fob no longer sees the car

The interval between turning on and off should be no more than 1 second.

• within thirty seconds, the system should automatically disable the security mode.
• If the system does not turn off, you must repeat the operation again. Emergency disarm for Tomahawk LR950

1. You need to get into the car and close the door;
2. turn on the ignition;
3. press the “Override” button four times;
4. turn off the ignition;
5. The parking lights will turn on/off 2 times, the siren will emit 2 “CHIRPS”, the security mode will turn off.

If there is radio interference or poor conditions, there is no feedback from the key fob to the car - you need to avoid such conditions, and if this does not work, tow your vehicle to a place where there is no exposure to radio waves. But if the main reason is in the alarm unit or electrics, then you need to contact a service center to fix the problem.

Tomahawk Quick Shutdown

If you need to go urgently (and according to the “law of meanness,” this usually happens), then it is better to use the emergency alarm shutdown procedure. On Tomahawks, the Valet button is used for this (here called Override according to the instructions). Moreover, in most Tomahawk models, to protect the machine, emergency shutdown is performed using a PIN code, but there is an exception in the form of Tomahawk 10.1. Whether the PIN code is activated in the system can be seen on the screen of the main key fob: there is an indicator of the same name.

To emergency disable the alarm without a PIN code, open the door with the key, then turn on the ignition as quickly as possible and press the Override button 3 or 4 times (depending on the model - we have already written about this earlier). After this, the ignition is turned off and the alarm goes out of security mode.

If PIN code protection is activated, then the shutdown procedure is different - open the car and turn on the ignition, enter the first digit of the code (for example, press the Override button 5 times for number 5), then turn off the ignition and turn it on again to enter the second digit. Next, enter the third and fourth digits in the same way if a three- or four-digit PIN code is specified in the system settings.

But what to do at the end of the trip if the alarm cannot be armed with the key fob? You should not leave your car unguarded. For this purpose, there is also an algorithm for turning on security without a key fob. With the door open, turn on the ignition, then press the Override button three times. After this, turn off the ignition and lock the driver's door with the key: 20 seconds after closing the door, the system will be armed, but will not control the central locking.

Error 404

To fix these problems, you need to replace the faulty part of the system. To do this, it is better to contact the service specialists. A mismatch between the key fob feedback and the alarm system can occur due to mechanical influences. When you press the buttons, the key fob emits a signal, but there is no feedback from the car. To restore operation and interaction, you need to open the car and turn off the alarm. Then, in accordance with the instructions, restore connection with the key fob. It is restored differently for different types of security systems. For the tomahawk alarm, the key fob is attached using the override button. Before binding, you need to read the instructions. On some systems, up to four key fobs can be linked at a time. Due to incorrect settings of the shock sensors, problems with the alarm triggering for impacts on the body may occur.

Settings Features

In order for the alarm to work correctly, you need to adjust the sensors before setting up:

1. First, find a sensor already installed in the cabin (as a rule, the device is located under the front panel).
2. Disarm the alarm system. Only after this is access to programming available.
3. The sensitivity scale has only a few levels, from 0 to 10. If the factory settings are installed, the indicator is at the fourth or fifth level.
4. The degree of sensor perception should be increased gradually. As rugelization progresses, it is necessary to check how and at what levels the devices operate.

How to set up and reprogram the key fob

In accordance with the technical manual, the communicator is configured as follows:

1. A working battery is installed in the key fob.
2. The key is placed in the lock and the ignition system is turned on.
3. The Jack button is pressed and held. The user needs to know in advance where this element is located (usually installers disguise it by wrapping it with electrical tape).
4. If the security complex has entered the binding and configuration menu, the siren should emit four beeps.
5. The service mode button is released.
6. On the communicator, the keys with two locks and a key are pressed simultaneously. If the siren sounds with a single signal, this indicates successful pairing of the remote control. To exit the setup menu, the user must take no action for six seconds.

How to set up autorun

Features of setting the engine to warm up automatically on command:

1. On the remote control you need to “click” on the key with the key icon.
2. If the engine starts without failure, the siren will emit a triple beep and the external lighting devices will blink three times.
3. An icon with the inscription “SE” will appear on the remote control screen, as well as an indicator of smoke from the exhaust pipe.

The nuances of setting up autorun by time:

1. In order for the motor to start at timed intervals, according to the timer, you must simultaneously press the buttons of the crossed out horn and the key. These keys on the remote control are held for several seconds until the alarm sounds. Successful activation of the option is accompanied by the appearance of an alarm clock icon on the key fob.
2. The start of the power unit will be carried out daily at the time when the user started.
3. If you need to set up the timer, then within five seconds after turning on the option you need to press one of the remote control buttons. If the start is made every hour, the key with the lock “clicks”, 2 hours - with the key, 4 hours - with the trunk open. To start the motor at a time interval of 12 hours, press the button with an indicator in the form of a crossed out horn.
4. If you want to disable the option, press the keys with the crossed out loudspeaker and the key at the same time.

The start of the power unit based on temperature is as follows:

1. The option is activated by simultaneously pressing the buttons with the open luggage compartment and the key. The parking lights or hazard warning lights should blink once, and the siren will also sound once. If the start is successful, an indicator in the form of a thermometer will appear on the key fob, and the start temperature will also be displayed. The communicator must also play a melody.
2. Using the key fob keys, you can set the starting temperature; it can range from -5 to -30 degrees.
3. To disable the option, you need to press and hold the key and trunk open buttons. The car's headlights will blink twice.

User Olzhas Zhaylaubay made a video in which he clearly showed the process of setting up automatic engine start on a car with the Tomahawk anti-theft system.

How to reset to factory settings

Good to know

Resetting or returning to factory settings will eliminate some software problems in the operation of the Tomahawk 9010 alarm system.

More information on how to reset Tomahawk 9010 to factory settings:

1. The car's ignition system turns on.
2. The emergency alarm maintenance button is pressed 10 times.
3. The ignition system in the car is turned off. The siren should sound ten times.
4. To reset and reset the parameters, the emergency mode button is “clicked” once.
5. On the communicator, press the button with the icon in the form of a key.
6. The ignition is turned on. The exterior lights should flash five times.

Emergency shutdown

To emergency deactivate the security system, perform the following actions:

1. The car's ignition system turns on. The siren and hazard warning lights will turn on as the alarm mode is activated.
2. The service mode button is pressed 4 times.
3. The ignition is turned off. If deactivation is successful, the lights will blink twice.

Tomahawk alarm key fob does not see the car

If you open the door with a key, the sound will not go away, but there are two effective ways to turn off the alarm in this case:

• Use the emergency shutdown function. Each alarm has a secret code that must be entered for emergency shutdown. The driver must remember the code when installing the alarm. To enter it, you need to find the Valet button from the alarm system in the cabin, which is responsible for setting up the system, connecting to the key fob and other functions. Most often, the button is located in the cabin near the fuse box, but if it is not there, you can look under the steering wheel, inspect the plugs, dashboard and other places in the cabin. When the button is found, you need to enter the secret code.

Video “Emergency alarm shutdown”

The video from Yakov Toporkov tells how to turn off the alarm if the key fob is faulty.

In the fall, my alarm suddenly died and I had to urgently look for a replacement. Several installers, as a consensus, suggested the Tomahawk TZ-9010, and what I especially liked was that the main argument for choosing was the following - there are no fakes for this model yet.

The alarm itself works as it should, but problems arose from time to time with the key fob - it seemed that a contact had come loose somewhere and the key fob was “rebooted.” In the fall, this happened quite rarely and was almost not annoying. It was somehow out of the question to visit the installers to sort everything out, but with the arrival of winter, reboots became more frequent.

It was a little annoying that the contact was lost in a very strange way, I shook the key fob, knocked on it, knocked with it - no disconnections. No matter how rough the road was under the wheels, the keychain remained silent like a partisan. And suddenly, as soon as you took it in your hands, there was a clear screen in front of your eyes.

In recent days he began to produce 5-7 trills in a row. He lies in his jacket pocket and “sings.” Take it in your hands, shake it - complete silence. I had to set aside time and go to the service. The solution to the problem turned out to be ridiculously primitive and once again confirmed the old truth - there is no need to deviate from proven solutions.

In the new tomahawk, the iron chain on which the car key is hung is attached not to the plastic ear on the remote control, as was the case with the old key fob, but to a metal contraption that fits directly into the case.

Tomahawk keychain old and new

Here he is - the conductor of static evil

This “thing” became a “bridge” through which static electricity penetrated inside the case and pierced the processor, causing it to reboot. In addition, for some unknown reason, it sharply reduces battery life. The number of disassembled key fobs on the installers’ table indicated that the problem was quite widespread. Maybe some batch was especially sensitive to statics, maybe something else.

With the advent of cold weather from the interaction of car seats and winter clothing, the volume of accumulated static increased noticeably and the frequency of key fob reboots also increased significantly.

Servicemen tried to glue the inside of the key fob body with conductive film from packages in which, for example, computer video cards and hard drives are packaged to protect them from static electricity. Unfortunately, these measures did not bring a long-term effect - the key fob went silent for two weeks, but then reboots/breakdowns reappeared.

Tomahawk alarm key fob does not see the car

The security system may react too often to minor noise or wind due to the increased sensitivity of the sensors. The opposite option for incorrect settings may be to set the sensitivity of the sensors to low, in which the shock feedback system does not work. Both problems can be solved by contacting the service for reconfiguration. Technical failure The car may not be deactivated due to serious technical reasons, which can only be resolved by a specialized service center. It can be:

• problems with the alarm control unit itself, associated with the disappearance of software from the main unit. It will need to be taken to an alarm installer for reprogramming;
• failure of the main alarm control unit leads to the need to change the entire system completely.

Many car enthusiasts have encountered the problem that the key fob can no longer see the car. Going to the service center right away can be cumbersome, so we will figure out what needs to be done in such cases. What does this look like in practice? The key fob doesn't see the car. The owner tries to open it with the key, but the alarm knows its job and goes off. The key fob does not show anything, even if you hit the car to trigger the sensor. First you need to try to move the car. It is possible that the communication channel between the car alarm and the key fob allows too much interference.

This often happens with a large accumulation of copper structures. This happens everywhere near cell towers. Most likely, you already checked the condition of the battery in the key fob, so you went for a spare key fob, but the situation repeated itself.

The most common malfunctions and their elimination

List of the main causes of breakdowns and errors due to which a car anti-theft installation stops working correctly:

• mechanical problems with the remote control - clogged or damaged contacts, board failure due to falling into water;
• low battery in the communicator;
• the vehicle enters an area of ​​serious electromagnetic interference;
• lack of normal conditions for transmitting remote signals between the microprocessor module and the key fob;
• wear and tear of structural components of the security complex;
• loss of synchronization between the vehicle and the remote control.

Communicator malfunction

Repair manual for a faulty key fob for controlling the Tomahawk 9010 alarm model:

1. First, you need to turn off the remote control; to do this, you need to remove the back cover of the device and remove the battery.
2. The next step is to disassemble the communicator. Parts of the device are fixed using self-tapping screws, which need to be unscrewed with a Phillips screwdriver. The fastening elements can be located either on the back cover or in a special compartment under the battery, it all depends on the year of manufacture and model - TW or TZ.
3. The two parts of the case are carefully separated from each other.
4. The display is removed from the device. If the screen is damaged, it is immediately replaced with a new one. It is almost impossible to find a separate display for sale, so it is recommended to monitor the secondary market. You can purchase a non-working key fob and use its parts to repair your communicator.
5. The buttons for remote control of the alarm are carefully removed. If they are damaged or the key guides are broken, the elements are replaced. Parts can be found in the same way as with the remote control.
6. The contacts connecting the buttons, display and antenna to the working board are diagnosed. If there is damage, they are re-soldered; this will require a soldering iron with tin and rosin. You must act carefully so as not to flood the circuit components.
7. At the next stage, the driver needs to check the integrity of the board itself. If this element is damaged, there is no point in repairing it; a complete replacement will be required. If there are traces of oxidation, clean the circuit using a dry cloth and alcohol. You cannot fill the board with liquid, as this will lead to its complete failure.
8. The circuit is checked for traces of mold. If the remote control has been dropped into water or exposed to moisture for a long time, it must be dried. It is not recommended to use a stove burner, open fire sources or a household hair dryer for this purpose. You should place the board in a dry and warm place for several hours, for example, next to the battery, but not in direct sunlight.
9. The capacitors and contact tracks on the circuit itself are checked. If the capacitor elements are swollen, they are soldered to similar ones. If you have no experience in performing such tasks, it is recommended to entrust this procedure to a specialist.
10. At the final stage, the components are assembled in the reverse order. If the control unit still does not receive signals from the remote control, it will need to be replaced.

The “NEKettle” channel filmed the process of repairing the communicator screen from the Tomahawk 9010 alarm system.

The battery has failed

It is important to know

The main sign of battery failure is a gradual decrease in screen brightness.

Troubleshoot battery problems as follows:

1. The back cover of the communicator is being dismantled.
2. The battery is removed from the device; if necessary, you can use a flat-tip screwdriver.
3. On the remote control, press the button to open the trunk door.
4. A new battery is being installed, and polarity must be taken into account. To replace cells, the manufacturer advises using only AAA alkaline batteries.
5. The back cover of the device closes.
6. On the remote control you press a button with an indicator in the form of an open luggage compartment.

Being in a radio interference zone

If the configured alarm functions are not performed or the anti-theft system responds inconsistently to commands, the problem may be interference from:

• large shopping centers, hypermarkets and supermarkets;
• collection vehicles;
• industrial companies and enterprises;
• airports;
• sensitive objects;
• transformer substations;
• large parking lots with cars.

To fix the problem, the user needs to do the following:

1. Take the communicator and bring it as close as possible to the transceiver installed in the car. Typically, transceivers are located in the windshield area.
2. Press the security mode disable button on the key fob.
3. If these steps do not help, then they must be repeated again after a few minutes. In order not to encounter such a problem again, you need to move the vehicle away from the interference zone by 100-200 meters.

If the security mode does not turn off, you can resort to the emergency deactivation method using the “Valet” key.

No conditions for wave transmission

The problem of lack of conditions for wave transmission usually manifests itself in the cold season. At low subzero temperatures, the battery voltage may not be sufficient to carry out commands. In particular, an anti-theft system installed on a car will not be able to open door locks or perform the function of automatically starting the engine. The only solution is to replace the battery or restore its functionality by recharging.

Wear and tear of the security system

It is important to know

To repair the alarm system if you suspect wear of the security system, you need to check the integrity of all components and replace damaged parts.

Items that need to be diagnosed:

1. Control block. It is necessary to check its connection to the wiring. If the connection is broken, it must be restored by cleaning and repairing contacts, as well as replacing cables. The reason may be the effect of moisture on the device, then you can fix the problem in the same way as in the case of the remote control. You will need to disassemble the module and dry its working circuit.
2. Transceiver with built-in antenna. Most often, the wire wears out at the bend in the connector connecting to the device. A detailed diagnosis of the connection quality and replacement of the cable or connector if necessary is required.
3. Circuit breakers. Depending on the installation method, there may be several of them. Safety elements are located on the electrical circuits connecting the siren and additional relays. Damaged parts must be replaced.
4. Shock and sensitivity sensor. Most often, the element fails as a result of vibration, since it is installed on the partition between the passenger compartment and the engine compartment. It is necessary to check the quality of the controller connection and the integrity of its wires; the latter are replaced if damaged. The cause of the problem may be that the configured sensor is not adjusted correctly, in which case the user should change the sensitivity level.
5. Siren. This device is located in an aggressive environment - under the hood of a car. Because of this, its malfunction may be associated with oxidation of the contacts or their damage. If the siren was installed with the horn facing up, this could lead to moisture accumulation inside the horn. To eliminate this, you will need to deploy the device.

Problems synchronizing the remote control with the car

Loss of synchronization between the remote control and the car can occur when the battery is disconnected or after replacing the battery in the key fob. To solve the problem, you will need to re-link the key fob to the anti-theft system.

Video: control unit repair

The Pavel Kalinin Autodiagnostics channel clearly showed the procedure for restoring the alarm control module.
