Keys with electronics for Smart

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

The part number is usually printed or engraved on the back of the Smart 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 Smart part number, which is the most reliable identifier.

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