How to turn off the car alarm without key fob – important tips and tricks

Ways to disable an alarm system on a car without a key fob

Most modern TZs are equipped with a security system, which is popularly called the simple word “alarm”. It performs protective functions and notifies the car owner of the desire of a criminal to break into the car. “Notifies” by means of a sound signal. In today’s market there is such a large selection of security systems for cars that it is easy to get lost with the choice. But not all of them are of high quality and reliability. As a result, the car owner himself may encounter with various troubles, even with the need to turn off the alarm system because of the key fob breakage. Well, in this article, let’s take a look at how to disable the alarm system on a car without a key fob.

How to disable the alarm system on the car without a key fob - important tips and tricks

Alarm Breakdowns

There can be quite a few reasons that lead to a breakdown. But the main one is poor quality equipment. Malfunctions can be caused by the failure of any car components, as well as too high or low temperatures. How do you know if the alarm is out of order? The first thing that will indicate a breakdown is a false triggering of the system. In any case, a broken alarm system can no longer be a reliable protector of your car. This means that it urgently needs to be repaired.

What causes a broken key fob?

  • Radio interference that interferes with the operation of the car security system.
  • The battery is dead or the battery in the key fob is dead.
  • Interruptions in the work of the car battery.

If the breakdown lies in the dead battery, then you need to take it out and shake it. For a few seconds this will resuscitate the device. At least you will be able to open the car. Afterwards, replace the battery with a new one.

How to disable the alarm without a key fob

If the problem could not be solved with the battery, then use the tips below.

Coded disconnection

This method is implemented by entering a special password, which the owner has previously come up with on his own. In order to carry out this operation correctly, perform the following actions:

    of your vehicle by opening the doors with the key.
  • Disregarding the depressing sounds coming from the “alarm”, turn on the ignition.
  • On the service (emergency, Valet) button with quick movements “click” that number of times, which fully corresponds to the first digit of the password you invented.
  • Now turn off the ignition.
  • To enter the second digit of the password, carry out all the same operations as with the first.

Valet Button

Emergency shutdown

To perform this operation, just as in the previous case, you need to perform a number of actions, steadily following the sequence. The main steps are indicated by the manufacturer. As a rule, it is necessary to turn the ignition key several times – first turn it on and then turn it off, in between pressing the Valet button. If there is no documentation, you will have to look for the key yourself. At this time, we recommend that you disconnect the terminals, so that the unpleasant squeak will not distract you from your work.

  • Turn off the ignition.
  • Switch it back on.
  • For 15 seconds, press the emergency button.
  • A signal will alert you to your move to “Dangerous” mode.


There are two ways to disable it: “emergency” and “standard”. To unlock the second way, you need after turning the ignition key, press the service button for 15 seconds, and then turn off the ignition back. How to perform this operation to enter the code is described above (in this “alarm” actions are similar).



How to disable this “alarm”? Perform the following actions:

  • Get inside your “four-wheeled friend”.
  • Switch on ignition (do not try to start the car, you will fail, otherwise you will lose the battery), and then for 6 seconds press the emergency button (Valet / service).
  • After that the system will beep, thus “telling” you that you have entered the service mode.
  • Turn off the ignition.

The sixth model “alarm” of this company will be disabled only by entering the code (password). Once in the car, press the Valet button the number of times equal to the first digit of your password. You must fit in 20 seconds, that is, press the button quickly. Turn off the ignition. With the other digits of your password, do the same steps: ignition, press the button the desired number of times, turn off the ignition.

  • Initially, it is necessary to open the vehicle, using the key.
  • After, as in all previous cases, you need to turn on the ignition.
  • The next step is to press the “emergency” button four times for no more than 20 seconds.
  • Turn the ignition key to the initial position (off).

If you have performed all operations correctly, the system will notify you with two beeps.


So, we told you how to unlock the most popular car alarm systems, why the “alarms” are failing and what contributes to it. We hope you will draw conclusions from this. Take note that you should not save money on security systems (after all, there is a saying for a reason – the miser pays twice), but you do not need to buy the most expensive (sometimes the brand name is three times more expensive than the product itself).

How to turn off the alarm with a key fob to start the engine

Possible causes of failure

There are several reasons why the alarm system on the car can break down, not work:

  1. Radio interference. The cause is especially urgent for large cities, where there are many radio towers, mobile communication stations, concentrated a huge variety of electronics, preventing the quality of the signal, including the signal from the remote keyfob of the security system. To fix the problem you can try to bring the remote control to the central control unit or to the receiver with an antenna, deactivating the siren.
  2. Failure of the remote control (key fob). This can happen after a hard blow (e.g. against the ground in a fall). Careless handling, prolonged use most often leads to failure of the closing and opening buttons. In this case you may need to repair or replace the remote control and register it to the anti-theft system. If water gets inside, contact oxidation may occur. They no longer carry current, the buttons do not respond to pressing. It is necessary to disassemble the key and carefully check the conductive elements. A common cause of malfunction is the discharge of the battery. It should be replaced with a new one. If the original remote control is equipped with one-way communication, you can check the battery charge by pressing the button. Signal lamp didn’t light up? The battery needs to be replaced. In case of two-way communication the charging indicator can be seen on the display.
  3. Low battery. The problem may occur even while the vehicle is moving. It can be detected by turning on the ignition. If there are no lights on the dashboard, the car’s battery is discharged. The door can be opened with the key, preliminarily turning off the “negative” terminal on the battery. To disable the alarm and start the engine, you can try to “bump” the car from another car. To activate the system again, you need to perform a series of actions. Most often – to press 6 times the key to open and close the door.

Tip: In order to avoid mistakes when trying to reactivate the anti-theft system in the car after it has been disabled, carefully study the instructions.

How to disable the alarm without a key fob

To disable the anti-theft alarm system on a car without a key fob, you can use one of 2 ways: emergency disabling or coding.

Emergency shutdown

Emergency disabling a car alarm is done with a Valet button – an emergency button to disable the alarm. It is most often placed:

  • Next to the fuse box;
  • under the dashboard.
  • near the pedal assembly;
  • behind the glove box;
  • under the steering column.

You can find out exactly where the emergency button is located by reading the owner’s manual. It also contains information on the combination of simultaneous pressing of buttons and pedals (one or both).

Tip: When looking for the emergency button to disable the alarm in the car, pay attention to the location of the LED indicator of the anti-theft. If it is in the front and to the left, you should look for the button somewhere nearby. Similarly, if it is in the middle or on the right.

It is desirable to previously remove the terminal from the battery to disable the buzzer. If you make several unsuccessful attempts to disable, the car alarm may automatically lock.

Important: Hold down the button on the car alarm and the depressed pedal for at least 10 seconds to disable it.

Coded disconnection

With coded disarming, the car alarm system is blocked with a PIN-code, which contains from 2 to 4 digits. It is known only to the owner of the car.
