The transmitter is integrated into the fob and its signal is picked up by antennas inside and outside of the vehicle.

When the receivers receive a signal, they deactivate the immobilizer, allowing the engine to turn over just like a normal key.

Keyless Remote Control

If your key fob isn't work, it could be a physical issue such as damaged battery connector contacts, or a button. It could also have an issue with the software, which requires reprogramming.

The transponder chip of the key fob transmits its identification back to the vehicle. The module that has the identity of the vehicle compares the key fob's identification to the one stored in the BCM and if they are compatible the vehicle can start.

This system is very effective at deterring most carjackers, though it does not protect against the more technologically-advanced thieves. In a recent study security researcher Bokslag was able to slyly get into the Immobilizer on three vehicles belonging to popular brands within ten seconds of obtaining the keys.

The majority of older cars use a simpler, less-reliable version of this system with a single permanent personal code and a revolving second code that's read each time the key is switched on. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.
