When activated by an electro-magnetic field the chip emits a low-level signal. The signal is received by a specific antenna attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for the car you have.

This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the car key verifies that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.

The circuit in the induction coil emits signals when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and an alarm. This is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure.

The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to drive.

Once the car is associated with a particular fob, it can only receive signals from the device. This means that other fobs will not work with the vehicle, even though they look the same.
