(Many cheap aftermarket keys only work when inserted into the slot).Regularly Asked Questions (FAQ)1. Can I purchase an utilized Mercedes key on eBay and program it myself?
No. As soon as a Mercedes key is programmed to a car, it is "locked" to that VIN. It can not be reprogrammed to another car utilizing standard tools. In addition, Mercedes keys need specific software and hardware to program; there is no manual onboard sequence to do it yourself.
2. For how long does the programming process take?

Keyless-Go allows the chauffeur to stroll up to the car, unlock, and begin the engine with a button without ever getting rid of the key from their pocket. These keys consist of more sophisticated proximity sensors and radio frequency transmitters, making the hardware and the programming more costly than basic "SmartKeys."

Programming a replacement key through a certified locksmith professional does not void the automobile's general service warranty. However, the dealer will not cover the expense if the aftermarket key itself fails.
