Triggers of the theft-deterrent system in your car

Forced entry alarm into the car trunk, hood, and door

Anytime someone is trying to break into your car, the anti-theft device system will go on. When thieves try to tamper with your car door or trunk locks, this triggers the anti-theft deterrent system.

The system automatically assumes that someone is trying to steal the car. But this is not always the case. At times, you could be trying to break the lock simply because you forgot your car keys.

Almost all modern anti-theft devices like car alarms get triggered by forced entry alarms. It is key to install an anti-theft system that gets triggered by this.

This way, you prevent thieves from running off with your car.

Duplicate car keys

In most instances, it is advisable to have a copy of your car keys. Think about it. If you lock your keys inside the car or even lose your keys, it can be devastating if you do not have a set of duplicate keys.

You would have to seek professional help or break your window to get your car keys. Always go to a reputable car locksmith and get a copy of your keys to be safe.

Nevertheless, using a copy of your keys can trigger your car’s anti-theft system. As soon as you insert a duplicate car key, the anti-theft device may prevent the car from moving.

And if it’s an alarm, it will go on. Of course, this depends on the type of anti-theft system you use.

If you use duplicate keys more often than not, install an anti-theft system that does not get triggered by this.

Typically, some anti-theft systems think that the person using a copy of your keys is trying to steal the car. And this might not be the case.

Tilt/inclination movements

Occasionally, thieves have to make some changes to the car before stealing. For example, they may have to remove the GPS tracker or modify the car’s electrical system.

Most car thieves always use a keyless technique to drive your car. What happens is that they tamper with the car’s system to make it move without requiring any car keys.

When this happens, the anti-theft systems get triggered. Moreover, some anti-theft devices get triggered by the simple inclination of a side mirror or wheels.

Some thieves are usually interested in stealing your car parts; luckily, this won’t happen if you have a reliable anti-theft device.
