Why Does Your Car Alarm Keep Going Off?

shock or impact sensors


Your car alarm system is an essential part of your car. It comprises four parts: a loudspeaker (of course), a keycode receiver, a computer, and some sensors (car door sensor, proximity sensor, microphone sensors, tilt sensors, shock or impact sensors, and many more, depending on its complexity). These sensors are very delicate and can misbehave if mishandled; hence you need to be careful carefulness whilein dealing with it.

Whenever these sensors or detectors receive a signal, the alarm does its job activating the loudspeaker. So, anytime the sensor starts failing, the alarm randomly goes off. Asides from this, there are many other reasons your car alarm keeps going off. Let’s look at some of them.

  • Faulty key fob or remote
  • The bad alarm control module
  • Low or dead car battery
  • Movement sensor
  • The faulty door lock sensor
  • Faulty hood latch sensor
  • Wrong installation of the car alarm

Faulty key fob or remote

A malfunctioning car remote can send the wrong signal to your car and trigger its alarm randomly. Therefore, you should check the remote batteries from time to time and reset them sometimes if need be. Some workshops specialize in reprograming your critical fobs if you need a hard reset.

The bad alarm control module

Car alarms often come with an integrated control unit coupled with an electric component control unit, especially if installed from the factory. Also, an aftermarket alarm system has a control module for all sensors and switches. If your alarm control module fails, your car alarm could continuously go off.

Low or dead car battery

For no other reason,  you should know your battery condition if you want your car alarm to work correctly. Your battery sends a signal when you are starting the engine. If the battery is low on power, your alarm goes off anytime you turn on the car. It is a way by which the car alerts you to replace your battery.

Although you can get help from a friend to jump-start it for you or call a mechanic, you should replace it soon after confirming its condition using a battery tester or multimeter. Also, your battery could be dead by morning because your alarm was working through the night.

In some cases, the battery is on sufficient charge, but the terminals carrying the charges could be faulty or corroded, therefore sending a low-battery signal to your car system. If corrupted, you can fix them by cleaning but ensuring safety gears and disconnecting the battery before proceeding.

Movement sensor

shock or impact sensors


Another reason your car alarm keeps going off is related to its motion sensor. This sensor is responsible for triggering your alarm if anything touches it. Different cars have different movement sensors, and their sensitivity depends on whether it’s an aftermarket alarm or from the factory.

With a diagnostic scanner, you can program the sensitivity of your movement sensor (if it is installed from the factory). Cars like Volkswagen and Audi often need this because their sensor is overly sensitive.

The faulty door lock sensor

Your car alarm system monitors the doors to ensure no door is open at any time. Whenever you leave a door open for too long, it tells on your car battery. A failing door latch sensor can cause your alarm to keep going off.

It is often installed inside your door lock actuator and can sometimes be found externally on the lock. Every door latch sensor has two wires for the open circuit when the door is left open and the other for the closed-circuit when the door is closed. You can use a multimeter to know its condition, though this is difficult because of its location, hence you may needneeding a professional.

Faulty hood latch sensor

hood latch sensor

Another sensor that could make your car alarm go off is the hood latch sensor located in front of your car. When someone tries to force your car hood open, the alarm goes off. Although, it can also go off randomly when your hood gathers grime, dust, and debris buildup.

It would be best to clean the hood latch sensor with a dry cloth to have this problem fixed. If the problem persists, it is most likely damaged or someone tampered with it. Sensors are rarely repaired; most times, you buy a new one altogether for better efficiency. Although, repairs can still be done by a professional because they can easily detect likely damage, and they have experience working with them.

Wrong installation of the car alarm

Not everyone knows how to install a car alarm; this is why you should get feedback about the services of a car professional before using them. Sometimes, when your car alarm keeps going off, it is due to faulty installation. Revisit the workshop that installed it and explain the problem, and if you did it yourself, you might need to double-check it all over again.

How Do You Turn Off Your Car Alarm Without the Fob?

Now, let us go into details of how to turn off your car alarm without the fob or remote. There are four methods to doing this:

1. Unlock the car manually using your keys

This is the first method to turn off your car alarm without the fob (it could be faulty). Insert your key into the lock on the driver-side door and turn to unlock it. If the warnings still have not gone off, open and lock the door a few times more.

If your driver-side lock is faulty, you can go through your passenger-side doors and turn on the car ignition. Although sometimes, the passenger’s side door may not open yet, it is almost impossible for your driver’s side not to open. Through this, you can shut off your car alarm.

2. Turn on the ignition using the keys.

After trying method 1 with no result, you can turn ON your ignition as a second method. The car recognizes your key and turns on the ignition signals that the vehicle is ready to move (without the alarm sound).

If the problem persists, start the car so that your car alarm can understand the signal. An additional step of turning on the dashboard light intermittently can strengthen the meaning of this signal to the car alarm.

3. Remove alarm fuse

The Honda Accord manual gives instructions on finding your car alarm fuse box. Often, it is located in the cabin; after identifying the fuse, you can remove it with the use of a nose plier. Then, the alarm will go off immediately and reset to default, and you can then place back the fuse.

If you notice the alarm, come back on immediately, and put the fuse back, then it is malfunctioning. In another case, it could reactivate after some minutes, which might be linked to a faulty electronic unit in the car.

4. Disconnect your car battery

This is the last resort to putting off your car alarm forcefully. First, open the hood and locate the battery or use our manual as a guide to finding the battery. Next, look for its negative terminal (usually the thick black wire or the one with ‘NEG’ or ‘-‘ mark on it) and disconnect it using a wrench.

You do not have to tamper with the positive terminal when doing this. Then wait for about 60 minutes before reconnecting the negative terminal to its original position. Again, remember to wear your safety glove protection from heat and scrapes.

How Do You Know if Your Car Has Anti-Theft Mode?

Your car’s manual is in the best position to make you know if your vehicle has an anti-theft mode. Security features pre-installed in the car make it hard to steal. Here are some of the security features that could be in your car

  • Passive disabling device (prevents activity on your car, without your presence)
  • Active disabling device (usually controlled to disable car devices using a key)
  • Car recovery system (an electronic system to recover your car by tracking it)

How Do You Bypass Anti Theft System?

You can bypass the anti-theft system by turning the key in the direction of unlocking your car without releasing it. Hold this key in the same position for about 30 seconds. This lets your car know that you have the right key and can allow you to bypass its alarm system. Read our section on How Do You Turn Off Your Car Alarm Without the Fob to know more.

What Is The Difference Between Active and Passive Car Alarms?
