How to disable the sheriff alarm

Ways to turn off the alarm

An analysis of experience in the practical operation of car alarms shows that there are several real ways to help disable the security system without using a key fob.

First way to disconnect

Method one, recommended by the manufacturer. It consists of putting the car into service mode using the “Valet” button. Of course, using this method of removing a vehicle (hereinafter referred to as “vehicle”) from the alarm system is possible only if you have information about its location. Depending on the make and model of the vehicle, the button that helps turn off the car alarm may be located:

slightly to the right of the accelerator pedal;
in the niche of the fuse box or in its immediate vicinity;
to the left of the clutch pedal;
in a small recess below the steering wheel;
behind the front panel.

In order to turn off the alarm without using the key fob, you must simultaneously press the “Valet” button and one of the pedals near which it is installed. The most common combination is “button + clutch pedal,” but sometimes you have to press both pedals simultaneously.

Second way to disable

Method two.
Also from the manufacturer, but it helps to disable the car alarm without using a key fob, only on cars of modern modifications. In this option, you can remove the car from the alarm system by manipulating the “Valet” button and the ignition system. Here is the sequence of recommended actions:

Open the door with the key, thereby activating the sound and light car alarm system;
Turn on the ignition without starting the engine, but after 2-3 seconds turn it off. When performing all subsequent manipulations with the key and ignition system, there is no need to start the power plant;
Press and hold the “Valet” button for a few seconds;
The alarm emits a short siren sound, indicating that the car is in emergency mode.

Thus, you can turn off the car alarm without using a key fob to carry out repair and restoration work on the security and alarm system.

Third way to disconnect

The third method consists of coded removal from the car alarm.
The essence of this method lies in the existence of a special identification code, without which it is impossible to turn off the car alarm without a key fob. The initial version of the identification code is formed as a two-digit number. Quite often this is an absolutely elementary combination, such as “96” or “11”. Stages of applying this method of disabling a car alarm without a key fob:

Opening the vehicle door, triggering the car alarm;
Turning on the ignition system (without starting the engine);
Pressing the “Valet” button. The number of presses corresponds to the first digit of the identification code, for example, nine if we are talking about the PIN code “96”;
Next, the ignition system is turned on again;
By pressing the service button, the second digit of the code is entered, etc. if the car alarm identification code consists of more than two digits.

After entering all the necessary numbers, the alarm system will go into emergency mode, which will be indicated by two short signals.

It is necessary to clearly understand the fact that the methods by which it is possible to turn off a car alarm without using a key fob may differ depending on the brand of alarm installed on the car. A common action for all types of security systems is opening doors using a key.

The battery is low;
The battery has moved from its place;
The buttons on the key fob are stuck.

In these cases, it is enough to check the key fob itself for mechanical damage. If you notice a faint glow on your dashboard, you can be sure that it is your battery that is dead. It’s good to always have a spare battery with you, but if you don’t have it, then you need to run to the nearest store for one.

Areas that had strong external radiation also interfere with the operation of the system. These could be nearby objects such as:

Regime enterprises;
Airport;
Parking lots with a large number of cars;
Cash collection vehicles;
Reinforced concrete structures;
Jammer type devices.

We must try to avoid proximity to such a zone. If you had to stop right there, then bring the key fob close to the system receiver and press the button. If it doesn’t work, tow the car two or three hundred meters away from the dangerous territory.

If this does not help, try reprogramming the transmitter codes. If the synchronization of the remote control with the car unit is out of sync, introducing a new program into the key fob channels can help. The Sheriff system has several physical wire lines that are functionally overwritten. To do this, it is best to refer to the repair and operation manual for the security alarm “Manually arming the system” or “Manually disabling the security system”.

If the system unit does not respond to anything, then most likely the software has disappeared. In this case, it needs to be reflashed, which can be done by specialized service companies for installing security systems.

You can use the Valet switch to turn off the beep. Valet is designed for programming the security system and its emergency shutdown. If you don't know where it is installed, it will be very difficult to find. Know that you will have to look for the Valet button while the siren is wailing. Open the car door with the key, remove the terminal from the battery so that the alarm sound stops, and continue to calmly search for the magic Valet switch.

If you don't know where Jack is, the siren will be heard throughout the area. It is better if you ask the former owner of the vehicle or the workers installing the security product in advance about the whereabouts of Valet. Turn on the ignition and press the button. The engine will be unlocked and the alarm will be disarmed. Valet has a code. As a rule, it can consist of the numbers two ones or three ones, or maybe one, two, three.

There are not many combinations, and they are usually simple. It also happens that it was not possible to find out where the Valet switch is located. In this case, you need to turn off the insulation power, all interlocks, and go to the service station for help.

Possible causes of malfunction

There are many reasons why the alarm system is faulty. However, you must definitely understand them in order to know how to turn off the alarm on your car. Reasons include:

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 charge level, especially in winter
. If the battery is low, you can open the doors simply with the key. But when you open the door, the alarm 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.
Damage to the key fob
(control panel).
This rarely happens, but it's still worth checking. This can happen due to the key fob falling, a strong impact, getting wet, or for externally unknown reasons (failure of microcircuit elements). The simplest failure in this case is battery discharge
. It is recommended to avoid this and promptly change the battery in the remote control. 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.

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’s signals. This also applies to the signals emitted by 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.

To turn off the alarm without using a key fob, one of two methods is used - emergency shutdown and disarming coding. But in any case, for this you need to know where the Valet button is located, which allows you to switch the alarm to service mode

You can read about where the Valet button is located in your car in the manual or ask the specialists who install the alarm system. Typically, alarm installers place them near the fuse box, or under the front dashboard. 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.

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. 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, or resort to unlocking by entering a code. But I advise you to call the alarm installation center (depending on what kind of alarm you have installed) and they will explain to you the exact procedure for turning off the alarm.

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.

How to turn off various types of alarms with your own hands

The above are general methods for disabling the alarm, but often for a particular model there are certain rules for carrying out the procedure, which we will dwell on in more detail.

"Tomahawk"

We will consider the procedure for deactivating a Tomahawk brand device using the example of the common RL950LE model. Disabling devices of other models involves similar manipulations:

We insert the key into the driver's door lock, ignoring the activated alarm;
We start the vehicle;
Press the service button 4 times in 10 seconds;
Turn the key in the ignition and turn off the car.

The car will notify us about the correctness of the procedure with a sound signal and blinking dimensions.

Video: how to disarm a Tomahawk alarm

"Alligator"

Below is an algorithm of actions in case of problems with the operation of the “Alligator” alarm system model D-810. To deactivate, follow the following sequence:

We get into the car interior by opening the door with the key (first remove the terminals from the car battery);
We insert the key into the ignition and turn it to the “ON” position;
Just press the service button once;
Turn the ignition key to the “OFF” position.

These manipulations give the driver access to the service mode of the alarm, while the security system stops working and all locks that prevent the vehicle from starting are removed.

Composition of modern security systems

To eliminate breakdowns that occur in the car security system, you need to know what is included. And the systems consist of:

Anti-theft system;
Immobilizer, which prevents car theft by immobilizing it;
Alert systems;
Sensors;
Blockers;
Castles.

The brain of the car security system is the immobilizer. When you press the key fob, signals are sent to the car, by which the car recognizes its owner.

Overview of models and operating and installation manuals

Sheriff APS-2500

An extremely primitive system without feedback, which is controlled by two key fobs with minimal functionality: one button controls arming/disarming, the second activates an additional channel, and in combination with the first, it implements arming with disabling sensors or silent mode.
This “Sheriff” alarm system can actually be considered a radio-controlled central locking module with a tiny share of security functions. With a standard installation, it is not at all difficult to disable it if the machine is hacked. Just look in the instructions to see how to disable the system without using a key fob:

Open the door with the key.
Turn on the ignition.
Press the Valet button within an interval of no more than 10 seconds.

Therefore, for the owner, setting a secret code is a mandatory measure to ensure at least some security. Here its length is fixed, two numbers from 1 to 9, which theoretically gives 81 different combinations. However, the instructions prohibit choosing the number 3 as the first digit of the code, which reduces the number of combinations to 72.

To set a secret code, you need to disarm the car:

Turn on-off-on the ignition.
Dial the first digit using the Valet button.
Turn off, then turn on the ignition again.
Dial the second digit.
Turn off and turn on the ignition.
After waiting for a short signal from the siren, turn off the ignition again.

But in order for the alarm to start working with a secret code, you need to activate the corresponding function:

After disarming the car, turn on the ignition.
No later than 3 seconds later, press Valet three times (this is why you cannot use 3 in the first digit of the secret code).
Turn off and turn on the ignition.
Press Valet 9 times, going to the F9 function.
Press the main key fob button - the system will give two siren signals, indicating that the F9 function has been switched to value 2 (secret code).

The procedure for disabling the security status using a secret code is the same as entering it.

Characteristics of the SHERIFF security system

Progressive Innovative Technology produces car alarms under the SHERIFF brand. PIT has been on the Russian market for more than ten years. Car security systems are designed for both Zhiguli and expensive American cars. All this is due to the joint development of American and Russian specialists. They achieved perfect adaptation of the system to any weather conditions in different regions of the country. Production takes place in China, and the main offices are located in Moscow and Kyiv. The range of models is very wide. This includes:

One-way alarms;
Two-way systems;
Alarms with auto start;
Three-channel control system;
Controlled from the vehicle's standard central locking device;
With built-in shock-motion sensor;
Car security systems with engine start.

Such security systems have advantages in pricing policy. They are quite affordable for any vehicle owner. The system also has many capabilities:

Finding your car in a parking lot among many cars;
You can select the tone you like in the sound signal;
Possibility of active or passive security systems;
Remote control;
Availability of a multifunctional system.

Despite the fact that this car security system is a reliable and high-quality product, it sometimes also experiences various types of malfunctions.

Ways to turn off the alarm

Emergency shutdown of the anti-theft system provides a number of alternative methods and techniques that will help the car owner emerge victorious from this situation.

So, let's look at the most effective methods for de-energizing a car's protective systems in various circumstances.

From keychain

The most simplified option in this case involves using a standard key fob. If the main remote control has died for a long time, you can always use a spare one, if available. Disabling the alarm using it involves the same actions as when using a standard remote device.

Difficulties arise when the location of the spare key fob is unknown. This state of affairs forces the driver to resort to other, more radical methods of solving the problem.

By de-energizing

The presented method of deactivating the anti-theft system includes a number of operational actions. Namely:

disconnecting the battery terminal;
de-energizing/dismantling the ignition switch control wire;
dismantling the blocking relay.

It is worth noting that in some cases finding a power relay is not an easy task. Often, for safety reasons, when installing an alarm system, the relays are located in hard-to-reach places

Using a secret button

Emergency shutdown of the anti-theft system involves the use of a so-called secret button called “Valet”. Activating it allows you to transfer the system to the so-called service mode.

If the owner has difficulty finding it, just find the control indicator - a flickering red light. This treasured button is also installed somewhere in the immediate vicinity.

So, the sequence of actions in this case is as follows:

de-energize the car by disconnecting the “+” terminal of the battery;
turn off the power to the sound siren;
put the terminal in its rightful place;
set the key to the “KZ” position;
make one click on the Valet button;
turn off the ignition.

The presented procedure for different types of anti-theft systems is strikingly different. In some cases, to obtain the desired result, it is necessary to make up to 6 short presses on the specified button.

In any case, before adopting this technique, it is advisable to read in detail the instructions for a specific type of alarm.

Coding

Another trick for car enthusiasts is the so-called coding. Its essence lies in the fact that to unlock the anti-theft system, you must enter a special code.

The presented procedure consists of the following steps:

turning off the siren;
circuit closure “short circuit”;
activation of the service button;
turning off the ignition.

Depending on how many symbols a particular PIN code contains, the above procedure is repeated for the same number of times. The PIN code is entered by pressing the service button. So, to enter 4, you need to press 4 times, etc.

What does the button look like?

To determine as accurately as possible what the Valet service key looks like, you need to look at the operating instructions.

The manual for any security system, including Alligator and Sheriff, contains images of all components included in the delivery kit. Depending on the manufacturer, this element may have a different shape and color of the insulating layer of the cable that powers it.

Description of the main appearance features that allow the consumer to recognize and detect the Jack key:

The button is small in size, as a rule, no more than 1.2-1.5 cm.
There are two wires connected to the key - power and ground. The color of the conductors may match the color of the standard cables. Experienced installers of anti-theft systems specifically change the wire in order to ensure hidden installation of the part.
On Sheriff alarms and other models, the button itself is located in the center of the black plastic case. It can be made in the form of a circle or square with rounded ends.

Professional help in disabling the alarm

The most common and affordable way to protect a car from illegal attacks today is an alarm system. Its activation and deactivation, switching of various functions is carried out using a control panel, popularly called a “key fob”.

The entire operation of the alarm system is based on the interaction of the electronic system and sensors with the elements of the car, therefore, like any other equipment, the alarm system can malfunction or break down. And such malfunctions can occur unexpectedly. For example, a person leaves work with the intention of quickly going home, but the alarm does not respond to commands sent from the key fob. And in the best case, the car can be opened with the key. So what's the problem? How to turn off the alarm on a car without a key fob? Let's sort things out in order.

The reason for the lack of response of the alarm system to the key fob signals

There are many reasons why the alarm key fob does not see the car and it is almost impossible to determine them at first glance. We list the most characteristic ones, from the most common to the rare:

Control panel malfunction.

First, if a malfunction occurs in the alarm system, you need to check the functionality of the key fob. There is a high probability that the batteries are simply dead. Therefore, the car does not open with the alarm key fob.

First of all, we check whether the screen lights up (if any) when you press the buttons. If there is no screen on the key fob, then a low battery can be indicated by a specially installed diode light on the case. How to disable the car alarm in such cases?

How to emergency unlock

If any unusual situations arise, an emergency disarming must be carried out immediately. For this, there is a separate procedure that every car owner should know.

Step-by-step instructions to remove a car alarm:

Emergency shutdown begins by opening the vehicle door (using a key). The alarm will go into alarm mode and start emitting loud sounds and bright light signals. You need to insert the key as quickly as possible and activate the ignition

In this case, it is important not to start the engine, since all the work will need to be done again. After that, look for the “Valet” button. At the request of the vehicle owner, it is located in the glove compartment, under the steering wheel or under the front panel. Press the key and hold it for 2 seconds. If everything is done according to the instructions, the headlights will blink once and the security system will exit emergency mode. Then press “Valet” again and hold it for 5 s. As a result of this action, the device will emit 2 beeps

In addition, the headlights will turn on and off twice, notifying the car owner about the emergency shutdown of the alarm.

Switching the system to Valet mode

If your alarm is not disconnected from the key fob, then the easiest way to disable it is to switch the system to valet mode. To do this, take a look at the technical manual included in the package. You need to start by identifying the installation of the emergency button. If you installed it yourself, then you know exactly where it is. Most often it is located under the control panel or near the fuse box.

After detecting the service key of the alarm, you need to follow the following algorithm:

Insert the key into the ignition. He must move to ACC position.
Press the button four times.
Insert the key into the lock and go to the ignition. Press the emergency button.
As a result, you will achieve deactivation of the ignition.

As soon as you have completed all the manipulations, turn on the engine and connect the siren contact in place. The algorithm for entering Valet may be slightly different.

Alarm Scher-Khan

Scher-Khan Magicar II

Quite a simple algorithm:

We open the car with the key.
In 3 sec. you need to have time to turn the ignition from the “ACC” position to the “ON” position 4 times.
Turn off the ignition.
As a result, the siren will turn off, the side lights will flash 1 time, and 2 more times after 6 s.
After this you will be able to start.

Scher-Khan Magicar IV

The following actions need to be taken:

We open the car with the key.
In 4 sec. you need to have time to turn the ignition from the “LOCK” position to the “ON” position 3 times.
Turn off the ignition.
As a result, the alarm mode will turn off, the side lights will flash 1 time, and 2 more times after 5 s.
Now you can start the car.

Scher-Khan Magicar 6

Here you need to know the code, which initially (if you did not change this value yourself) is “1111”:

We open the car with the key.
In 4 sec. you need to have time to turn the key in the ignition switch from the “LOCK” position to the “ON” position 3 times.
Turn off the ignition.
We repeat step 2, only the number of times the key positions are changed will be equal to the 1st digit of the code.
We repeat point 3.
After 4 sec. the alarm will blink once, indicating the possibility of entering the next digit of the code.
Repeat steps 2 and 3 until all code numbers have been entered. In between, we wait for permission to enter the next digit.
After entering the 4th digit, the alarm will blink 2 times.
If the code is correct, the siren will turn off and you can start the car.

The following video shows how you can disarm your car without using the key fob:

Why you may need to disable the security system

Manual switching off of the alarm is necessary when faults are detected. The reasons for this are:

a short circuit occurred inside the alarm system, the cause of which was the sensitivity of the sensors, a sharp and strong signal from a neighboring car;
failure of the remote control key fob;
loss of radio key fob;
lack of a spare key fob in case of loss of the main one;
completely discharged battery;
delay in unlocking the car caused by loss of the car signal;
radio interference caused by a large number of nearby cars.

Consequently, the alarm security system is a very complex mechanism, the operation of which depends on most factors. It is directly connected to the opening of doors, the ignition switch, and the internal combustion engine. In addition to the above-mentioned cases, it is often necessary to completely disable the alarm in cases where the car is left in a protected area for a long time. Next, let's look at how you can turn off the alarm.

How to completely deactivate a security system

In a standard situation, deactivation occurs by pressing the desired key on the key fob. If lost, in many cases a spare one is used, but there are also cases when there is simply no spare key fob. Let's look at how you can completely turn off the alarm on your car:

by pressing the Valet button;
entering a PIN code;
by pressing the emergency shutdown button;
blackout.

Important!
These methods are standard, therefore, they may not be suitable for some machines at all.

If you need to disable the alarm, you should re-read the package insert you received when purchasing the car. As a rule, it always contains all the necessary measures to disable the alarm system.

The alarm does not turn off with the emergency button: what to do?

Having looked at how to turn off the alarm on a car without a key fob using the Valet button, it should be noted that for a number of obvious reasons this method will not always work. The driver may simply not know the location of the button or may not have a secret code to deactivate the security system.

Moreover, if the car beeps, but there is no way to turn off the alarm, this can create inconvenience. It is also often impossible to start the engine, since modern car alarms usually block the start of the internal combustion engine.

We also recommend reading the article about what central locking is in a car and how it works. From this article you will learn about the purpose, operating principles and features of the central lock in a car, as well as about common problems, repair methods and do-it-yourself central locking installation. To get rid of the sound, you can remove the terminal from the battery or use wire cutters to cut the wire under the hood that goes to the siren. This will work with older alarm models, but most likely not with new systems. The reason is multi-stage protection, autonomous power sources for sirens, etc.

You can also try to find the relay and/or fuse that supplies power to the alarm control unit. The task is not easy, since modern alarms have contactless relays; this element is placed in hard-to-reach and hidden places. However, if successful, the alarm will be de-energized.

Where is?

Since the Jack button performs an emergency disabling of the security mode, it should be located as secretly as possible so that the criminal cannot use it.

If the installation of the anti-theft system is not carried out independently, a specialist can install the key anywhere in the cabin. The car owner must be informed where exactly the part is located. In most cases, you need to look for the key under the instrument cluster (it can be disguised in one of the bundles with standard wiring). To prevent a criminal from quickly unlocking the security mode, the installer could wrap the wires and the part itself with electrical tape for more reliable protection.

Possible locations for installing the Jack button:

in the free space on the audio system;
under the driver's seat;
in the plastic trim of the steering wheel near the ignition switch;
in the free space behind the central part of the dashboard;
behind the glove compartment;
under the ashtray;
in the area of the parking brake lever.

If you need to find the location of the key for the Panther alarm or any other model in the car, you must perform the following steps:

Calculate the location of the microprocessor module, which may be located under the instrument cluster or in the free space behind it. If difficulties arise at this stage, you can use power circuits with a positive contact that come from the battery or ignition switch. Sometimes it is advisable to use the negative output connected to the battery or a standard bolt screwed into the body of the vehicle.
Carefully examine all the pads on the microprocessor module. If the consumer still has the service manual for the alarm, then the documentation will allow you to understand the purpose of the pads. One of the outputs on the microprocessor unit is intended for connecting a service button.
If documentation is missing, it is necessary to check each wire coming from the control unit. Usually the key is connected through a separate connector designed for 2 or 4 contacts. Sometimes, to search, you will need to dismantle the interior trim.

If you have difficulty determining the location of the control unit, then on Starline A91 alarms and other models you can proceed as follows:

The search algorithm consists of listening to the relay installed in the module. The user must get behind the wheel of the car and lock the door. The engine must be turned off. It is important that the vehicle is located in the quietest place possible, away from roads with heavy traffic.
While the driver is in the cabin, he needs to turn the alarm on and off as many times as necessary to determine the relay clicks. When activating and disabling the security mode, their number must be multiple.
If the control unit is detected, it is necessary to check each wire coming from it.

If the security system is configured for silent activation or silent security mode, then clicks will not be heard.

In Pandora anti-theft systems, the settings key is located on the transceiver module, which is usually installed on the windshield or rear window. However, this button is not a Jack; the latter is located secretly separately from the antenna.
