Mercedes-Benz keys, spares and no-start problems

Mercedes-Benz keys I can help with

Most Mercedes from the late 1990s onwards use a remote key fob with an emergency blade tucked inside, rather than a traditional key that turns in a barrel. The fob slots into the ignition, and many newer models use Keyless-Go with push-button start instead.

Mercedes keys are tightly matched to the car, so they can’t simply be cut and copied. When you call, give me the model, year and registration and I’ll tell you what’s possible for your car.

Common Mercedes-Benz key problems

• Remote buttons still work, but the key does nothing in the ignition — see the steering lock note below.
• Key fob case cracked or the hidden blade lost.
• Remote stopped locking and unlocking the doors.
• Only one key left.
• Sprinter or Vito key lost on a busy work day.

Not sure which applies? Call and describe what’s happening, or send a WhatsApp with a photo of your key and your reg.

Mercedes-Benz models I’m often asked about

• A-Class and B-Class
• C-Class
• E-Class
• CLA, GLA and GLC
• ML and GLE
• Sprinter, Vito and Viano

Not listed? I work on most Mercedes-Benz models, so call with the year and registration and I’ll confirm.

Buttons work, but the ignition does nothing?

On many older Mercedes — especially C-Class (W204), E-Class (W212 and W207), Sprinter (W906), Vito and Viano — a failed electronic steering lock (ELV) can stop the car starting even though the key is fine. I’ve written a separate page about it: Mercedes ELV repair.

What happens when you call

Tell me the model, year and registration of your Mercedes-Benz, and whether you still have a working key. I’ll confirm the price by phone, then come out to the car — at home, at work or at the roadside. The new key is cut where needed, programmed to the car and tested on the doors, remote and engine before I leave.

Price

I quote each job individually because the key type and the car make a difference. You’ll know the price before anything is booked, and work comes with a 1-year guarantee.
