Keys

Nearly all modern vehicles require some kind of transponder fob or transponder keys to operate, ensuring security and anti-theft protection.

If you want to program a new key, the first step is to ensure that your car is operating. Insert the key you wish to reprogram into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets the commands and exits programming mode. It is crucial to move quickly and do not wait between each step. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a sound that indicates that the process was successful.

This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.

A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition, a magnetic field is created around the transponder. This produces a signal which is taken up by the coil, which sends it to the key's identification number. The ID number of the key is transmitted back to the vehicle and if it matches the engine will start.
