The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the right one for your specific vehicle.

A circuit within the induction coil emits signals when the transponder is put into an ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as valid, it will disable vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and a siren.

The receiver then compares this information with the 'allowed' signals stored inside the fob, and 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 allowed to operate.

After the car has been connected to a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they look the same. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
