It might signal a danger, when very loud music is played, an accidental bump in the parking lot, and light collision shock from two pets. This thing may consequently lead to a force alarm.

Key Fob Problems
One of the most reasons why a vehicle alarm keeps going off is a broken key fob. The fob key is a little remote control for unlocking your car door, which has been developed into the unlocking mechanism of your vehicle. Pressing a button on the key fob is all that is needed to operate the device.
In other cases, a broken key fob can send wrong signals to the auto computer system even when you haven’t touched the button. Due to this your car alarm will go off because it has received a warning signal unexpectedly. Sometimes a weak battery level of your key fob can result in a mistaken activity which can cause your car alarm to go off. However, it’s difficult to figure out this cause as your key weak energy levels are usually not displayed on the screen.
Damaged Electrical Wires
If you are using an old car is possible the connection between wires has become weak. The protective case of the battery can also be eroded. This can affect the voltage transmission hence making the sensor trigger off to any potentially dangerous warnings. Generally, a sudden voltage drop can occur when a thief tries to cut off any electrical wire that is linked to unlocking your vehicle.
Low Vehicle Battery
Your car alarm can be activated if your battery is dead. Sometimes the frequent sounding of your vehicle alarm is a result of a dead battery. When your battery runs out completely the sensors will record the situation as a sudden drop in voltage.
Due to this, the computer recognizes the signal from the sensors and in turn gives out warning sounds the vehicle battery fails. You can use a voltmeter to determine whether or not your battery is the cause. For instance, if your voltmeter measures your battery charge level below 12.6 volts, then you can conclude the battery is the cause of your vehicle’s alarm activation.
Other reasons include;
- A damaged bonnet latch sensors
- An incorrectly installed car alarm
- Bad connections in the control unit
- A defective door lock sensor
