![]() ![]() ![]() We have the equipment and ability to program the majority of cars using transponder keys. ![]() On some makes and models you can add an additional key if you have 2 existing operational keys and on a few only 1 key is necessary to add a duplicate or program a new key. Programming a duplicate or replacing a lost key usually requires special programming equipment, there are some exceptions. The key then sends a signal back to the car, if the signature matches the the car will start. The key then powers up using power from the antenna ring (there is no battery in the key on standard transponder keys and the battery in smart keys isn't necessay for the transponder to work). PCM repair will focus on the coordination of all of these modules. When the key is turned in the lock or the smart key is present the vehicle sends a signal to the key. The PCM governs the ECU and TCU, along with close to 100 other functions of the vehicle. ![]() There is a chip embedded in the head of the key that has a unique code. The basic system consists of a transciever ring (antenna) a immobilizer module (some manufacturers) connected to the PCM (computer) and a transponder key. Car immobilizer systems have been used since the mid 1990's and now are used on about 90% of the cars on the road. ![]()
