This allows the vehicle’s computer system to determine if the transponder chip inside the key is the correct one for your specific vehicle.This is what prevents hot-wiring or tampering with the ignition system of your vehicle to get it started.

The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.If the vehicle doesn’t recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and a siren. programming car key is designed to discourage individuals from tampering with the vehicle.

If the data does not match, the car will not be allowed to drive.After the car has been connected to a specific fob, it can only receive signals from the device. Other fobs won’t work with the car, even though they appear like.
