Keys with electronics for Mercedes-Benz

The page is filtered to Mercedes-Benz only — every listing is a remote key matched to Mercedes-Benz models, with button layouts, frequencies, and blade profiles corresponding to Mercedes-Benz vehicles.

The part number is usually printed or engraved on the back of the Mercedes-Benz key housing, on a label under the battery, or on the circuit board once opened. The frequency — such as 433, 434, or 868 MHz — may be printed alongside it or determined from the Mercedes-Benz part number, which is the most reliable identifier.

We cut the Mercedes-Benz blade from a clear photo of your original key for €5. We do not program — programming a Mercedes-Benz key requires a direct connection to your vehicle and must be done locally by an independent garage, auto electrician, or professional vehicle locksmith.
