The key should be compatible with the on-board computer of the vehicle, and also have an appropriate keyring positioned around the ignition barrel. In most cases, this type of reprogramming requires the use of a transponder cloning machine, which is able to copy a specific transponder, or circuit board. This equipment is available from some major blank manufacturers as well as experts in reprogramming.
