An electronic key fob is a remote control device that allows you to lock, unlock, and start your vehicle. Programming is necessary when adding a new key or replacing a lost one.
If your vehicle is equipped with FBS3 encryption technology (Most Mercedes-Benz models between 1996 and 2014), a key can be programmed by a third party such as a locksmith or module programmers like us at Mercedes Benz Specialist. We require the Electronic Ignition Switch (EIS) to program a key. It must be removed from the vehicle and shipped to us.
No. 2015+ models have FBS4 encryption. Only the Mercedes-Benz Dealers can program a key. The aftermarket technology has yet to start programming FBS4 Electronic Ignition Switches or keys.
If your key fob is not working, experiencing intermittent issues, or if you've recently replaced the fob, it may require programming. Consult your vehicle manual or reach out to our experts for guidance.
Key fob programming is not typically part of routine maintenance. It is usually performed when adding a new key fob, replacing a lost or damaged fob, or addressing issues with the existing fob.
No. If your vehicle did not come equipped with Keyless Go, programming a key or an EIS is more complex than it sounds. Keyless Go uses various modules throughout the car.
