Why Does you Car Alarm Keep Going On

If your car’s alarm won’t shut off, it may be because of one of these reasons:

1. Malfunctioning Key Fob

In case you are not familiar, a key fob is the plastic controller that can lock and unlock your car’s door, as well as shut off the alarm. However, if the key fob is malfunctioning, it will not be able to send the proper signal into the car’s alarm system, which results in the alarm going on and off.

2. Poor Connection of the Hood Latch

The hood latch might set off false alarms just because the sensors are not responding properly to the given commands. This is the reason why your car alarm seems to go off even after you have the hood latch sensors cleaned. It should also be noted that this issue can also cause trouble to the control unit, which can result in incorrect readings to the signals.

3. Rust Battery Terminals

Another reason why your car alarm keeps going off is that the terminals are already worn out. If this happens, the battery will not be able to supply enough power to the different car components. With this, the sensor might interpret this condition as the car having low battery and it might go off to tell you about it.

4. Low Battery

One of the main functions of the car alarm system is to warn you that the battery levels are low. You will notice that if you try to turn the engine on with a low or already dying battery, the alarm will set off. To check the battery, you may try using a voltmeter. If the reading shows less than 12.6V, it might be the best time to replace the battery.

5. Hood Latch Sensor is Dirty

In case you did not know, the hoot latch sensor collects grime and grease, which results in malfunctioning. In the event the hood latch sensor is malfunctioning, it often triggers the alarm to go off. As well all know, this sensor is what protects your car from damage, theft, and the unintentional opening of the hood. This is the main reason why you should always have your hood latch sensor cleaned, as it enhances the car safety.
