automotive key programming are a standard feature in modern cars and are designed to stop car theft.

This makes it more difficult for novice car thieves to hot wire a vehicle and then start it.


A circuit board equipped with an induction coil that connects the key to the chip. When the key is inserted into the ignition, it creates an electric field around the transponder. This creates a signal which is taken up by the coil and sent to the key identification number. The key's ID number is then sent back to the vehicle and if it matches, the engine will begin to run.
