The key is purchased through the Vehicle Identification Number (VIN) and is programmed at a main center before being shipped to the dealer.
The Professional Locksmith Route
Not all locksmith professionals can manage Mercedes-Benz keys. Just those with specialized diagnostic devices and software application licenses can program keys for these automobiles. This is generally limited to designs utilizing the FBS3 system; FBS4 designs (usually 2015 and newer) almost specifically need dealership intervention.

Q: Can I set a Mercedes key myself?A: No. Unlike some domestic lorries that permit "onboard programming" utilizing two existing secrets, Mercedes-Benz needs proprietary diagnostic tools (like Xentry or specialized locksmith professional software application) to interface with the car's computer system.

Q: How long does it take to get a new key?A: If purchased through a dealer, it normally takes 2 to 5 business days as the key is shipped from a central warehouse in New Jersey (for the US market). A specialized locksmith can typically do it in 1 to 2 hours if they have the blank in stock.

Q: My key turns in the ignition but the car won't start. Do I need a new key?A: Not necessarily. This could be a problem with the Electronic Steering Lock (ESL) or the Electronic Ignition Switch (EIS). A diagnostic scan is needed to figure out if the fault lies with the key or the lorry's hardware.
