Mobile Mercedes-Benz key replacement near you
Mercedes-Benz keys are some of the most secure on the road. We help Mercedes owners across Oakland and Macomb County with key diagnostics, spare keys, emergency blades and Sprinter van keys, and we'll tell you honestly when a dealer-ordered key is the best route.
Many Mercedes keys are made for your specific vehicle using its VIN. In those cases the process is to verify ownership, order the key, then complete setup. We handle that process so you don't have to tow the car anywhere.

Mercedes-Benz keys and fobs we replace
Chrome SmartKeys
The classic Mercedes key used on many 2000s and 2010s models, with a hidden emergency blade.
Keyless-Go fobs
Keyless entry and start fobs for newer C-Class, E-Class, GLC and GLE models.
Sprinter van keys

Why some Mercedes keys take a few days
Many Mercedes keys are produced to match your car's VIN and security data rather than cut and programmed from a blank. If your car uses this system, plan a few days for the key to arrive. That's another reason to replace a lost spare right away.

Mercedes-Benz key replacement FAQs
Can a locksmith make a Mercedes-Benz key?
It depends on the model and year. Some keys can be done on site; many newer keys must be made to the VIN, which takes a few days. Call with your VIN and we will tell you exactly what is involved.
Do you make keys for Sprinter vans?
Yes. We help with Sprinter van keys and spares for owners and business fleets.
My Mercedes key stopped working. Is it the battery?
Often, yes. Replace the battery first. If the car still does not respond, the key may need diagnosis or replacement.
How much does Mercedes-Benz key replacement cost?
It depends on the model, year and key type. A basic Mercedes-Benz transponder key costs less than a push-to-start smart key, and making a spare costs less than replacing every lost key. Call (586) 623-2403 with your year, model and VIN for a firm quote before any work starts.
