Key fobs emit a signal on the same radio frequency as a cell phone, and this technology can be used to remotely activate certain car features like lift gates that power up or to start the engine from outside the car. Fobs also can trigger an alarming sound to scare away thieves and other unwanted guests.

Batteries are by far the most frequent reason for an unresponsive key fob. If this is the case, the process of changing the fob's program is done by following a few simple steps.

The transponder chip in the key fob sends its ID back to the vehicle. The module that knows about the identity of the vehicle checks the ID of the key fob against the BCM and should the two match, the vehicle will begin.

This system is very effective at deterring most carjackers, though it does not protect against the more technologically-advanced thieves. In a recent article, security researcher Bokslag managed to stealthily crack three popular brands' immobilizers within ten seconds after obtaining keys.

The majority of older vehicles use a less reliable, simpler version of this system. It is based on one code that is personal, that is permanent as well as a second code that changes each time the ignition key is turned.
