The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for the car you have.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and notify you via flashing lights and an alarm.

The receiver compares this information to the signals that are allowed on the fob and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.

After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs won't work with the car, even though they look like.
