Key fobs that are newer use RFID (radio-frequency identification) to communicate with the computer in the vehicle. They transmit a digital identity code to the car computer saves this code to ensure that the key fob can unlock and start the car.

Fobs also can trigger an attractive blare to frighten away thieves and other unwanted guests.

The transponder chip in the key fob then transmits its ID back to the vehicle. The module that knows the identity of the vehicle compares the key fob's ID with the one stored in the BCM If they match the vehicle will be able to start.

This system is very effective at deterring most carjackers, though it does not protect against the more technologically-advanced thieves. In a recent report security researcher Bokslag managed to hack three popular car brands' Immobilizers within a matter of ten seconds after receiving keys.
