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

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure.

However, car key reprogramming cost of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.

The receiver then compares this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.

Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, even though they appear similar. This safeguards the integrity of the computer system in the car and prevents unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is a dealer's service department. Certain aftermarket fobs, typically ones for older models with less sophisticated systems, can be programmed without the need for a dealership.
