When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer inside the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding siren.

If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.

Once the car is connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, despite the fact that they look like. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.

Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer.
