The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for the car you have.

If the car's computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and an alarm.

The receiver compares this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.
Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they look like.
