How to turn off the alarm on a car so it can start. Disabling the signaling Sherkhan, Alligator, Tomahawk, Starline, Sheriff

Most drivers don't know how to turn off the alarm on your car. But such a need may arise at the most unexpected moment, for example, if the car does not respond to the key fob. You can disable this system using different methods - by turning it off, using a secret button, and also using software. Next, we present to your attention detailed information on how to disable the “Starline”, “Tomahawk”, “Sherkhan”, “Alligator”, “Sheriff” and others, which are popular in our country.

Possible causes of failure

There are not many reasons why the alarm system failed. However, you must definitely understand them in order to know how to turn off the alarm on your car. So, the reasons include:

Presence of radio interference .
This is especially true for megacities and places with large concentrations of cars and various electronics. The fact is that modern electronic devices are sources of radio waves, which under certain conditions can interfere and jam each other. This also applies to the signals emitted by car alarm key fobs. For example, if next to your car there is a car with a faulty alarm system that emits its own signal, then there are times when it interrupts the impulses sent by the “native” key fob. To resolve this, try moving closer to the alarm control unit and activating the key fob there. Internals of the alarm key fob
Damage to the key fob (control panel). This happens quite rarely, but this hypothesis should still be tested. This can happen due to a strong impact, getting wet, or for externally unknown reasons (failure of internal microcircuit elements). The simplest failure in this case is battery discharge . This should be avoided and the battery in the remote control should be changed in a timely manner. If you have a key fob with one-way communication, then to diagnose the battery, just press the button and see if the signal light lights up. If this does not happen, the battery needs to be replaced. If you use a key fob with two-way communication, then on its display you will see a battery charge indicator. If you have a spare key fob, try using it.
Car battery discharge . In this case, all systems of the machine are de-energized, including the alarm system. Therefore, it is necessary to monitor the battery level, especially in winter . If the battery is really low, you can open the doors simply with the key. However, when you open the door, the alarm system will go off. Therefore, we recommend that you open the hood and disconnect the negative terminal on the battery. To turn off the alarm and start the engine, you can try “lighting” it from another car.

The considered problems can be eliminated in two ways - with or without the use of a key fob. Let's look at them in order.

What determines the price of dismantling a car alarm at a service station?

The easiest way to remove the alarm is to contact a service station. It should not be surprising that the price for removing a car alarm is often no less than installing a new one. Typically, the cost of work is estimated at more than 2,000 rubles. It can be much more significant if:

two-way alarm system;
there is an automatic engine start system;
original methods of engine blocking were used;
special sensors are installed;
there is an output for control via GSM or satellite channel;
the alarm system is combined with an immobilizer;
body tracking is organized not via a CAN bus, but by electrical wiring to the end switches of the doors, hood and trunk.

It may take more than one standard hour to dismantle all non-standard electrical wiring and security system devices. If the service station is guided by European repair standards (standard hour from 20 Euro, or 1,400 rubles), then 5 hours, according to calculation, for example, will cost about 7,000 rubles. In this case, it’s time to think about doing the work yourself.

How to turn off the alarm without a key fob

To turn off the alarm without using a key fob, use one of two methods - emergency shutdown and disarming coding. However, in any case, for this you need to know the location of the Valet button, which allows you to switch the alarm to service mode . Otherwise, she will be “on edge,” and it will be impossible to approach her without consequences.

Varieties of “Jack” buttons

You can read about where the “Valet” button is located in your car in the manual or ask the specialists who install the “alarm”. As a rule, alarm installers place them near the fuse box, or under the front dashboard (there are also options when the Valet button was located in the area of the driver's pedals, behind the glove compartment, under the steering column). If you do not know where the button is located, then focus on the location of the alarm LED indicator . If it is installed in the front left side of the cabin, then the button will be there. If it’s on the right or in the middle, then you also need to look for the button nearby.

If you buy a car second-hand, be sure to ask the previous owner about the location of the mentioned button.

The two methods presented (emergency and coded) are so-called “fast” methods. That is, they can be implemented in a matter of seconds without the need to climb and understand the car’s electrical wiring. Next, we will consider these two methods separately.

Options for the location of the “Jack” button

Emergency shutdown

In this case, in order to turn off the standard alarm, you must know the sequence of actions to be performed. As a rule, this is a certain sequence of turning the ignition on and off and several clicks on the mentioned secret Valet button. In each individual case, this will be its own combination (the simplest is to turn the key in the lock and briefly press the button). While you are looking for the secret button and remembering the PIN code, so as not to irritate everyone around you with the howling of your car, you can at least remove the terminal from the battery. The alarm will stop “yelling” and you, in a calm environment, will decide on your actions - either remove the battery and slightly deform it (sometimes it helps when it’s dead), or resort to unlocking by entering a code. Next, we will look in more detail at the combinations for alarms popular among domestic car enthusiasts.

Coded shutdown

The definition of “coded shutdown” comes from an analogue of a PIN code, which has from 2 to 4 digits, which are known only to the owner of the car. The procedure goes something like this:

Turn on the ignition.
Press the “Jack” button the number of times that corresponds to the first digit of the code.
Turn off the ignition.
Next, steps 1 - 3 are repeated for all numbers that are in the code. This will unlock the system.

However, the exact sequence of actions is indicated only in the instructions for your car or the alarm itself. Therefore, unlock only if you are completely sure that your actions are correct.

Why do you have to disable the immobilizer?

VAZ began to equip immo only with injection-type cars. The first anti-theft devices of this series appeared on the VAZ 2110 and they were called APS-4. Today, more modern APS-6 models are more common. Now all cars of the 2110 to 2115 series are equipped with this particular device.

The most common problem with this device is the loss of the key or if the car owner, without knowing it, erased its code. Speaking specifically about VAZ standard immos, you can more often encounter a problem related to the fact that the lights in the cabin do not go out and, as a result, the alarm does not go off. In addition, malfunctions of the immobilizer software often occur, as a result of which its central unit does not read information about the key or considers it “not native”. As a result, when you stop to refuel, you risk being left in a stalled car.

To reprogram (marry, bypass, flash, upgrade, adapt) a device, you must first turn it off. In addition, immobilizers are usually disabled when installing a car alarm.

How to turn off car alarms

The simplest, but “uncivilized” and emergency method of turning off the alarm is to cut the wire that goes to its sound signal with wire cutters. However, most often such a number will work with old alarm systems. Modern systems have multi-level protection. However, you can try this option. To do this, use the mentioned wire cutters or simply pull out the wires with your hands.

Another option is to locate the relay or fuse that supplies power and controls the alarm. As for the fuse, the story is similar. The old “alarm” may turn off, but the modern one is unlikely to. As for the relay, finding it is often not an easy task. It is necessary to go by the opposite method to find its location. The situation is complicated by this fact. that often in modern alarm systems the relays are contactless and can be placed in unexpected places. But if you are lucky enough to find it, disconnecting it from the circuit will not be difficult. This will de-energize the alarm. However, the described methods are no longer suitable for emergency shutdown, but for alarm service . Although it is better to entrust this process to professionals.

Next, let's move on to a description of how to disable individual alarms, which are popular in our country among car enthusiasts.

Dismantling the signaling, step-by-step instructions

If the standard battery has not been disconnected, the power supply from the car alarm is disconnected as follows: you need to find the pre-flask through which current flows to the alarm, and disassemble the body of the bulb by hand. Then you can remove the fuse so that the supply voltage does not go to the main module.

How to fix this problem is discussed further.

Installing jumpers in the connector terminal block

When installing a security alarm, it can be equipped with immobilizer functions. One or more relays are connected to the break in the wires responsible for powering “important” equipment (fuel pump, starter). The windings of these relays are connected to the main car alarm module (to the blocking outputs).

There are two options:

The power wires are connected to the following two contacts: common, normally closed;
The power cable at one of the points is connected to a normally open contact.

In the second case, obviously, the engine will not start until current flows through the relay winding.

If it is determined that the first option is being used, then the terminal block is simply disconnected and isolated from the car alarm connector. For the second case, everything looks more complicated. But the situation can be corrected on your own without dismantling the relay. See the main connector diagram.

The blocking relay can be connected to output “1” or to output “12”. Sometimes both options are used, and you, in turn, need to do this:

On the terminal block, install a jumper between contacts 1-9, try to start;
If the engine does not start, disconnect contacts 1-9 and connect the other two (12-9);
Lastly, try installing two jumpers (1-9 and 12-9).

How to disable “Sheriff”

How to disable the “Sheriff” alarm

Let's start with the Sheriff brand, as one of the most common. The algorithm for unlocking it looks like this:

it is necessary to open the car interior with a key (mechanically);
turn on the ignition;
press the Valet emergency button;
turn off the ignition;
turn the ignition back on;
press the Valet emergency button again.

The result of these actions will be the alarm exiting the alarm mode into the service mode, after which you will be able to find out the cause of the malfunction in the system.

How to disable “Alligator”

Alarm kit "Alligator"

The ALLIGATOR D-810 alarm can be turned off in two modes - emergency (without using a transmitter) and standard (using the “Valet” button). The choice of coded mode is selected by function No. 9 (see the section in the manual called “Programmable functions”). The standard shutdown mode consists of the following steps (with function No. 9 enabled):

open the car interior with the key;
turn on the ignition;
in the next 15 seconds, press the “Jack” button once;
turn off the ignition.

Note! After completing the described procedures, the alarm will not be in the service mode (“Valet” mode). This means that if the passive arming function is activated, then after the next time the ignition is turned off and all doors are closed, a 30-second countdown will begin before directly arming the car.

It is also possible to switch the alarm to service mode using a code. You can install it yourself. The numbers used can be any integer value in the range from 1 to 99, except those containing “0”. To disarm you must:

open the car interior with the key;
turn on the ignition;
turn off and turn on the ignition again;
in the next 15 seconds, press the “Jack” button the number of times that corresponds to the first digit of the code;
turn off and on the ignition;
in the next 10...15 seconds, press the “Jack” button the number of times that corresponds to the second digit of the code;
turn off and turn on the ignition.

Repeat the procedure as many times as there are numbers in your code (no more than 4). If you did it correctly, the alarm will go into service mode.

Remember that if you enter the wrong code three times in a row, the alarm will become unavailable for some time.

Next, let's look at how to turn off the ALLIGATOR LX-440 :

open the salon door with the key;
turn on the ignition;
within the next 10 seconds, press the “Jack” button once;
turn off the ignition.

After completing the described procedures, the alarm will not be in service mode. To remove the lock using a personal code, proceed similarly to the previous description. However, please note that this alarm code consists of only two digits , which can be from 1 to 9. So:

open the door with the key;
turn on, turn off and turn on the ignition again;
after that, in the next 10 seconds, press the “Jack” button the number of times that corresponds to the first digit;
turn off and turn on the ignition again;
within 10 seconds, using the “Jack” button, similarly “enter” the second digit;
turn off and turn on the ignition again.

If you enter the wrong code three times in a row, the system will be unavailable for about half an hour.

Alligator alarms have a normally open blocking relay. Therefore, it will not be possible to disable it by simply removing the connector from the alarm control unit. But with the STARLINE alarm, such a number will work, because there the blocking relay is normally closed.

Shutdown process

In theory, the process looks simple - the connector is disconnected from the protection, which gives a signal that the anti-theft is physically absent. After this, the immobilizer data is erased from the ECU memory. That's all. But how can this be done in practice? Let's try to figure it out.

But you can get out of the situation. Two main methods have been developed for this:

Wire cutting;
Reprogramming.

Let's talk about each method separately:

Trimming

Locate the immobilizer control unit (usually behind the center console at the audio level).
Find the connector and remove it from the block.
The connector has 20 pins. Count the ninth and eighteenth wires - cut them off. Now connect together, make insulation.
After removing the device, restore the diagnostic line. To do this, install a communication jumper between the diagnostic block and the ECU. Cutting and connecting the wires allows you to restore the K-Line.
Put the connector back.

How to turn off the Starline alarm”

Disabling the Starline alarm

Sequence of actions to disable the Starline 525 alarm :

open the car interior with the key;
turn on the ignition;
in the next 6 seconds you need to hold down the Valet button;
after this, one sound signal will appear, confirming the transition to the service mode, and the LED indicator will go into slow blinking mode (it lights up for about 1 second, and goes out for 5 seconds);
turn off the ignition.

If you have a Starline alarm model A6 installed, it can only be unlocked using the code . If the above models also have a personal code installed, then the algorithm of actions will be as follows:

Keychain Starline

open the interior with the key;
turn on the ignition;
in the next 20 seconds, press the “Valet” button the number of times that corresponds to the first digit of the personal code;
turn off and turn on the ignition again;
again, within 20 seconds, press the “Valet” button the number of times that corresponds to the second digit of the personal code;
turn off the ignition.

Instructions for disabling the alarm system STARLINE TWAGE A8 and more modern:

open the car with the key;
turn on the ignition;
within no more than 20 seconds, press the “Jack” button 4 times;
turn off the ignition.

If you did everything correctly and the system is operational, you will hear two beeps and two flashes of side lights, which notify the driver that the alarm has entered service mode.

Linking a new key fob

Every motorist can restore normal operation of the security system in the event of loss of the alarm key fob. The new control element must be linked to the old security system. This process is described in the instructions, it may differ depending on the type of alarm. The general points are as follows:

the system is switched to “valet mode” mode by pressing the corresponding button or lever in the car interior;
switching to the mode may require entering a security code, which is additional protection (the code is displayed in the instructions);
An important point is the number of key fobs that can be connected to the system; if you connect an extra one, the code will be erased from the first one.

If you take these points into account and strictly follow the instructions for linking a new key fob, then everything will work out, since anyone can replace a car alarm key fob. There are no difficulties in this process.

Do not rush to change the alarm system if problems arise with its key fob. Solving the problem can be much easier and cheaper. Of course, if the system is old and key fobs are no longer available for it, then it will be easier to install a new alarm system.

How to disable Tomahawk alarm

Disabling the “Tomahawk RL950LE” alarm

Let's look at unlocking the Tomahawk alarm using the RL950LE model as an example. You must act in the following sequence:

open the car with the key;
turn on the ignition;
within the next 20 seconds, press the “Jack” button 4 times;
turn off the ignition.

If unlocking is successful, the system will notify you with two sound signals and two flashes of signal lights.

In what cases is it necessary to disable the immobilizer?

There are a number of cases when there is a need to turn off this device:

If it is defective from the factory and because of this the machine does not work properly. As a rule, this occurs on the very first car models.
If the computer battery is completely discharged and prevents the engine from starting.
If the ECU has blocked it.
It also happens that the system is worn out and requires replacement.

As we can see, there are different reasons for disabling the immobilizer. It should be understood that this procedure is very serious and quite complex. You need to know all the subtleties.

Simply unplugging the connector can completely shut down the entire engine starting system.

How to turn off the Sherkhan alarm

Let's start the description with the SCHER-KHAN MAGICAR II . The sequence of actions is as follows:

open the car with the key;
within 3 seconds it is necessary to turn the ignition from ACC to ON 4 times;
turn off the ignition.

If you did everything correctly, then in confirmation the car will turn off the siren, the dimensions will blink once, and after 6 seconds two more times.

Disabling SCHER-KHAN MAGICAR IV is performed according to the following algorithm:

open the car with the key;
within the next 4 seconds, you need to turn the ignition 3 times from the LOCK position to the ON position;
turn off the ignition;

If you did everything correctly, the alarm signal will disappear, and the side lights will blink once, and after 5 seconds 2 more times.

If you have SCHER-KHAN MAGICAR 6 , then you can disable it only by knowing the code. When installed, it is equal to 1111. The sequence of actions is as follows:

open the car with the key;
within the next 4 seconds, you must have time to turn the ignition key 3 times from the LOCK position to the ON position;
turn off the ignition;
turn the ignition key from the LOCK position to the ON position as many times as the first digit of the code;
turn off the ignition;
Next, you need to repeat the steps of entering all the digits of the code with the ignition turned off.

If the information entered is correct, then after entering the fourth digit, the alarm will blink its side lights twice and the siren will turn off.

Please note that if you enter the wrong code three times in a row, the system will be unavailable for half an hour.

If you did not manage to meet the designated time (20 seconds) and find the “Jack” button, let the alarm calm down and calmly look for the mentioned button. After you have found it, close the door again and repeat the procedure. In this case, you will have enough time to turn off the alarm.

Be sure to remember or write down the first two digits of the code. They are used to record codes for new key fobs.

Subtleties of engine control

If autostart is not used, the alarm should not read data from the engine. Otherwise, it is necessary to implement control that allows you to turn off the starter at the right time. The control itself is usually carried out like this:

The signal can read the value of the supply voltage;
The cord from the generator is connected to the terminal of the VAZ-2107 tidy - the control cable can be connected to this terminal;
It is best to control the launch using the tachometer, for which the alarm will still need to be configured.

The third option is preferable. The cord is not connected directly to the tachometer terminal, but through a capacitor and resistor:

Generator and tachometer outputs

Direct connection is used for “generator” control.

In practice, only one control method can be used. First, installation and connection are performed, then the system is configured.

How to disable the Leopard alarm

LEOPARD LS 90/10 EC alarm is similar to the previous case. An emergency mode of alarm removal is also possible using a personal code. In the first case, the actions are similar - open the car, get into it, turn on the ignition and press the “Valet” button 3 times. If you need to enter a code, then the steps will be as follows - open the door, turn on the ignition, press the “Valet” button as many times as the number corresponds to the first digit of the code, turn the ignition off and on and enter the remaining numbers in the same way. If you did everything correctly, the alarm will turn off.

Disabling the LEOPARD LR435 occurs in the same way as the case described.

How to disable the CENMAX alarm

the CENMAX VIGILANT ST-5 brand alarm will be as follows:

open the door with the key;
turn on the ignition;
press the emergency shutdown button four times;
turn off the ignition.

Disabling the CENMAX HIT 320 occurs according to the following algorithm:

open the interior door with the key;
turn on the ignition;
Press the “Jack” button five times;
turn off the ignition.

If you did everything correctly, the system will respond to this with three sound and three light signals.

How to disable the FALCON TIS-010 alarm

To put the immobilizer into service mode, you need to know the personal code. Sequencing:

open the door with the key;
turn on the ignition, the indicator will light continuously for 15 seconds;
when the indicator flashes, quickly, within 3 seconds, you must press the “Jack” button three times;
after this, the indicator will light up for 5 seconds and begin to flash slowly;
carefully count the number of flashes, and when their number matches the first digit of the code, press the “Valet” button (the indicator will continue to flash);
repeat the procedure for all four digits of the code;
If you entered the information correctly, the indicator will go off and the system will be switched to service mode.

If you want to transfer the car for long-term storage without an alarm function (for example, to a car service), you can use the built-in “Valet” mode function. For this purpose, the immobilizer provides a “disarmed” mode. If you need the “Jack” mode, then proceed in the following sequence:

disarm the immobilizer;
turn on the ignition;
within the next 8 seconds, press the “Jack” button three times;
after 8 seconds, the indicator will light up in a constant mode, which will mean that the “Jack” mode has been activated.

The trained key is lost. What to do

If the trained key is lost, it is necessary to re-train the remaining key. This is necessary to prevent an attacker from using the found trained key. The procedure for learning the remaining key (or a purchased new one) is carried out according to the same scheme, with the only difference being that the LED indicator at the beginning of the learning process does not light up constantly, but blinks at a frequency of 2 times per second.

Chip key VAZ 2110

If the training key with the red mark is lost, you will have to change the immobilizer-electronic engine control unit pair and retrain the purchased keys. Training a clean immobilizer and keys is carried out in the manner described above. Using the same scheme, a failed immobilizer is replaced, having a red training key and two black working keys available.

How to disable CLIFFORD Arrow 3

To enable the “Valet” mode, you need to enter a code. To do this, follow the following sequence of actions:

press the PlainView 2 switch located on the vehicle's dashboard or console x1 button the required number of times;
press the unlabeled button (if you need to enter “0”, you must press the button immediately).

To enable the “Valet” mode, you need to:

turn the ignition key to the “ON” position;
enter your personal code using the PlainView 2 button;
hold the unlabeled button pressed for 4 seconds;
release the button, after which the LED indicator will light up in a constant mode, this will serve as confirmation that the “Jack” mode is turned on.

To turn off the “Valet” mode you need to:

turn on the ignition (turn the key to the ON position);
Enter your personal code using the PlainView 2 switch.

If you did everything correctly, the LED indicator will turn off.

How to disable KGB VS-4000

Disabling this alarm is possible in two modes - emergency and using a personal code. Let's start the description with the first method:

open the doors with the key;
turn on the ignition;
within the next 10 seconds, press and release the “Jack” button.

If you did everything correctly, then in confirmation the siren will emit two short beeps, and the built-in speaker of the key fob will emit 4 beeps, and the icon LED will flash on its display for 15 seconds.

To unlock the alarm using a personal code you must:

open the car door with the key;
turn on the ignition;
within the next 15 seconds, press the “Valet” button as many times as the number corresponds to the first digit of the code (remember that the first press of the button must be no later than 5 seconds after turning on the ignition);
if you have more than one digit in the code, then turn off and turn on the ignition again and repeat the entry procedure;
When all the numbers have been entered, turn off and turn on the ignition again - the alarm will be cleared.

If you entered the wrong code once, the system will freely allow you to enter it again. However, if you make a mistake a second time, the alarm will not respond to your actions for 3 minutes. In this case, the LED and alarm will work.

Results

Finally, I would like to draw your attention to making sure you know where the “Jack” button is located in your car . After all, it is thanks to it that you will be able to turn off the alarm yourself; check this information in advance. If you bought a car secondhand, then ask the former owner for the location of the button so that, if necessary, you know how to turn off the alarm on the car so that its engine will start and you can continue to operate it. Also, be sure to find out what kind of alarm system is installed on your car, and accordingly, study the sequence of actions to disable it.
