To program a new car key you must first verify that your car is running. Insert the key you wish to reprogramme into the ignition, but don't turn it. You have just a few minutes before the system will reset all commands and exits the programming mode. It is essential to move quickly and do not be patient between each step. Turn off the engine to prevent this. You can test the car's system by turning the key to the "on" position, then back to the "off" position.

Transponder chips

Transponder chips, which are used to prevent car theft are a standard feature of modern automobiles. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car then detects the signal and then starts the engine if it matches the original one that was programmed into the vehicle. The car is also programmed to stop when it detects an incompatible frequency. This makes it difficult for novice car thefts to hot-wire a vehicle and then start it.

A circuit board equipped with an induction coil connects the chip to the key. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is absorbed by the coil and then transmitted to the key identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will start.
