Mercedes-Benz Key Replacement

Mercedes-Benz uses a proprietary immobilizer system centered around the Electronic Ignition Switch (EIS) and the Engine Control Module. Mercedes keys use infrared communication in older models and encrypted proximity signals in newer ones. The key must be registered with both the EIS and the ECU to start the vehicle.

Our technicians program Mercedes-Benz keys using professional diagnostic equipment that communicates with the EIS module. We handle chrome keys for older models and Keyless Go smart fobs for current vehicles. We offer multiple key options for most Mercedes models. The cost depends on your vehicle's year, model, and key type — contact us for a free, accurate quote.

The C-Class, GLC, and E-Class are the Mercedes models we see most in Atlanta. We also service the GLE, GLS, S-Class, Sprinter, and the full lineup.

Models we cover: Mercedes-Benz C-Class · Mercedes-Benz E-Class · Mercedes-Benz S-Class · Mercedes-Benz GLA · Mercedes-Benz GLB · Mercedes-Benz GLC · Mercedes-Benz GLE · Mercedes-Benz GLS · Mercedes-Benz A-Class · Mercedes-Benz CLA · Mercedes-Benz CLS · Mercedes-Benz AMG GT · Mercedes-Benz EQS · Mercedes-Benz EQE · Mercedes-Benz Sprinter · Mercedes-Benz Metris

Mercedes-Benz Car Lockout Service

Mercedes-Benz vehicles use advanced central locking with multiple locking stages, including comfort closing that seals all windows and the sunroof when locking. The precision engineering of Mercedes door assemblies requires a careful approach.

We use non-destructive entry methods with extra care for Mercedes-Benz finishes, trim, and seals. Our technicians understand the specific door geometry across the C, E, S, GLC, and GLE platforms.

Mercedes-Benz Key Fob Programming

Mercedes-Benz key fobs feature the Keyless Go system with proximity entry and start. The fob communicates through encrypted signals with antenna modules in the doors, trunk, and center console. Some models support Mercedes me connect features through the fob as well.

We program Mercedes Keyless Go fobs and standard chrome keys on-site. Each key is registered with the EIS module and verified for all functions, including proximity unlock, push-button start, and trunk release.

Pro Tip: Mercedes Keyless Go fobs have an emergency key blade concealed inside the fob. The driver's door handle also has a hidden keyhole behind a removable cover for manual entry when the fob battery is dead.

Mercedes-Benz Ignition Repair

Mercedes ignition problems often involve the Electronic Ignition Switch (EIS), which can develop internal faults that prevent key recognition. On older models, the EIS may fail to read the key's infrared signal. Push-button start models can have antenna ring or EIS module issues.

We diagnose Mercedes EIS and ignition faults at your location. Our equipment communicates with the EIS module to determine whether the issue is the key, the switch, or the module communication, and we repair what we can on-site.
