The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip in the key is the right one for your particular car.

A circuit within the induction coil emits signals when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will notify you via flashing lights and a siren.

The receiver compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.
Once the car has been paired with a specific fob, it only accepts signals from the device. Other fobs won't work with the car, despite the fact that they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealerships will only accept cars with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by consumers without the need for a dealership.
