When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is taken up by an antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for your particular car.

This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

The chip is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a regular standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

A circuit within the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.

If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security.

The receiver compares this information with the signals that are allowed in the fob and then either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to run.

Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they appear similar.
