The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for your specific vehicle.

This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.

Keyfobs can be programmed in various ways based on the model and make of your vehicle. Some cars allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.

When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is linked to. The receiver compares the information with the permitted signals stored on the key fob and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.

Once the car has been associated with a particular fob, it will only accept signals from the device. As a result, other fobs won't be able to work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
