433MHz frequency and non-OEM design

The remote transmits on a 433MHz frequency and is a non-OEM accessory rather than an original Mercedes Benz part. Compatibility depends on matching the FCC ID and part numbers of your existing remote exactly. Vehicles that use a different frequency or have a different remote layout will not work with this fob.

Programming requires a locksmith or dealer

The fob arrives with a CR2032 battery installed and a complete internal circuit board, but it must be programmed and the key blade cut by a qualified locksmith or dealership. Programming takes only a few minutes once the correct equipment is available. Owners who cannot access a locksmith or dealer able to program this specific remote will not be able to use it.
