The key must be compatible with the onboard computer of the vehicle and include an appropriate keyring positioned around the ignition barrel. This type of reprogramming typically performed using a transponder cloning machine, which can copy a specific circuit board or transponder. This equipment is available from some major blank manufacturers as well as experts in reprogramming.
