Car Key Programming

 

A transponder chip disarms your vehicles immobiliser when the car key is used to start the engine. The majority of keys to cars built after 1995 contain transponder chips. When the car key is turned in the ignition, the engine control unit (ECU) on the car sends an electronic message to the key, and it will allow the car to start only provided it receives the correct message back. So, even for a simple car key without any buttons, the key must be cut correctly to turn the locks, and also programmed correctly to disarm the immobiliser. Car keys with chips can be programmed using special equipment that we have here at AutoKeys R Us.

Car key programming

Remote keyless entry fobs emit a radio frequency with a designated, distinct digital identity code. In general, the procedure is to put the car computer in ‘programming mode’. This usually entails engaging the power in the car several times while holding a button or lever. It may also include opening doors, or removing fuses. The procedure varies amongst various makes, models, and years. Once in ‘programming mode’ one or more of the fob buttons is depressed to send the digital identity code to the car’s onboard computer. The computer saves the code and the car is then taken out of ‘programming mode’. Here at AutoKeys-R-us, we can program approx 90% of all vehicles on the road.
