Keys

Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys must be programmed to your particular car and its systems by a certified dealer or locksmith.

Do you know whether the unit has been programmed to work with a different vehicle or if yours can be programmed again?

If you're looking to program an entirely new key first, you need to ensure that your vehicle is on and running. Insert the key you wish to program into the ignition, but do not turn it. There are only a few seconds left before the system resets all commands and leaves the programming mode. For this reason, it is essential to move fast and not pause between steps. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. You should hear a sound indicating that the process was successful.

The vehicle is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for car thieves with no experience to hot wire a vehicle and then start it.

The chip and the key are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal, which is absorbed by the coil before being sent to the key's identification number. The key's identification code is transmitted back to the car, and the engine starts if the identification number matches.
