In this way, how does a passive anti theft system work?

Passive and active anti-theft devices are the two options available when considering an anti-theft system. Passive devices automatically arm themselves when the vehicle is turned off, the ignition key removed, or a door is shut. No additional action is required.

One may also ask, what triggers the anti theft system in car? It's possible that the anti-theft system in your car won't function correctly at some point. This may be for many reasons including a dead car battery that loses its key memory or a dead battery in your remote. It could also be that your immobilizer chip is damaged in your key or the car door lock is damaged.

Moreover, how does the car alarm work?

The way a car alarm works is simple: when the alarm is switched on and a sensor receives a response, the alarm sounds. When the sensors don't record any unusual activity, the car alarm remains active but silent and unnoticeable.

What is a passive disabling device on a car?

An automatic, or passive, car disabling device is one that works without the driver having to enable it. One is a transponder key, or smart key, which most new vehicles have. These keys won't allow a vehicle to be driven if the corresponding key's not present.
