The computer system of the vehicle can then verify that the key’s transponder chip is the right one for your car.This prevents the vehicle from being started by either hot-wiring or by manipulating.

The signal will be received by the chip, causing it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.If the car isn’t able to recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and an alarm.

Certain models allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.When you press the button on your key fob, the microchip inside transmits an encoded code to the car’s radio that it is paired with.

In turn, other fobs won’t be able to work with the vehicle, even though they have the same appearance.
