The keys have a chip inside. The chip included is a 48 chip. This chip must match the engine computer in order to start the vehicle, so professional programming is required. This ignition switch comes with 2 keys. The chip is not pre-programmed. To resolve this, you can: - Have a local locksmith duplicate the key from your original, programming the chip to match your vehicle's existing key. - If you do not have the original key, a locksmith can use a programming device connected to the OBD2 port to program the vehicle to accept the new key.
