Our Mercedes-Benz Key & Lock Services
Lost keys, lockouts and older metal-key barrels, plus two separate Mercedes jobs: EIS / EZS ignition and ESL / ESCL steering lock. Both are carried out at your home, workplace or roadside.
Lost Mercedes-Benz Keys
Complete replacement when every key is lost or stolen. We read the immobiliser, cut a new blade to factory spec and code the transponder to your vehicle on-site.
Mercedes-Benz Key & Fob Repair
Split case, buttons that no longer respond, or a blade snapped in the lock? Repair is often far cheaper than a full Mercedes-Benz key replacement.
Mercedes-Benz Spare Keys
Cut and programmed at your door for a fraction of an all-keys-lost job. Essential if your Mercedes-Benz is down to a single key.
Key Fob & Keyless Programming
Immobiliser light staying on or central locking gone dead? We programme Mercedes-Benz transponder chips and remotes on the models and years we cover.
Emergency Vehicle Opening
Keys locked inside your Mercedes-Benz? We open Mercedes-Benz vehicles without damage to the door, lock or glass, then get you moving.
Ignition Barrel Replacement
For older Mercedes-Benz models with a metal-bladed key that sticks, jams or spins in the lock. We repair or replace the worn mechanical barrel and match it to your existing keys.
EIS / EZS Ignition
Key will not turn, the dash stays dead or the Mercedes will not start even with a working key? That is the Electronic Ignition Switch (EIS / EZS) — a separate job from the ESL steering lock. We diagnose, repair or programme the module and sync it to your keys on the models and years we cover.
ESL / ESCL Steering Lock
Steering locked and the key will not turn on a later Mercedes? That is the electronic steering lock (ESL / ESCL) — a separate job from EIS / EZS ignition and from a worn metal key barrel. We repair, replace or programme an ESL / ESCL emulator at the vehicle.
Instrument Cluster Coding
Dash dead, a used cluster fitted after a repair, or mileage that will not sync? We code a new or used instrument cluster at the vehicle on the Mercedes-Benz models we cover. Coverage is confirmed from your registration.

Mobile Mercedes-Benz Key Replacement Across London, Surrey, Sussex & Kent
Mercedes key work is year-sensitive. We cover a defined list of older Mercedes cars and vans at your vehicle across London, Surrey, Sussex and Kent. If your registration falls within our supported years, we cut and programme the key on-site without a dealer appointment or recovery truck.
Our vans carry the blanks, cutting machinery and diagnostic equipment needed for the Mercedes models we support. You can see the whole of our coverage area on the areas we serve page. Always give us the registration first so we can confirm the year is within range before dispatching.
Lost every Mercedes key? Check the year first, then we come to you.
All-keys-lost is routine work on the Mercedes models we cover. We read the immobiliser or decode the door lock at the vehicle, cut a fresh blade, and programme a new transponder or remote so the vehicle starts and locks normally, usually inside the hour and without recovery.
Mercedes Models and Year Limits We Cover
Coverage is limited to these ranges: A-Class up to 2012, B-Class up to 2015, C-Class, CL, CLK, CLS, E-Class, M-Class, SL/SLS and SLK up to 2014, S-Class up to 2013, Sprinter up to 2016 and Vito up to 2014. Newer Mercedes models outside those years are outside our Mercedes coverage.
If you are unsure of the year, call 07921 365 247 or use the registration quote panel above. We will confirm coverage before anyone is sent.
Mercedes Sprinter and Vito Van Keys
A Sprinter or Vito off the road is lost income. Within our year limits — Sprinter up to 2016 and Vito up to 2014 — we come to the depot, yard or roadside to cut and programme van keys without recovery. If your van is down to one key, order a spare before the next emergency.
Mercedes EIS / EZS Ignition
EIS / EZS is the electronic ignition switch. If the key will not turn, the dash stays dead or a working key will not start the Mercedes, the fault is often this module, not the key and not the steering lock. We diagnose, repair or programme the EIS / EZS and sync it to your keys on the models and years we cover.
Mercedes ESL / ESCL Steering Lock
ESL / ESCL is the electronic steering lock. If the steering is locked and the key will not turn, that is a different job from EIS / EZS. We repair, replace or programme an ESL / ESCL emulator at the vehicle on the Mercedes years we cover. Confirm from the registration first.
How Our On-Site Mercedes-Benz Key Service Works

- Key cut and coded. We cut the new blade to your vehicle and programme the transponder chip or remote using our own diagnostic equipment.

"C-Class key failed on a 2012 model. They confirmed the year was covered, came to my work car park and coded a new one the same day."
"Lost the only key to my 2015 Sprinter on a job. They cut and coded a replacement at the roadside so we could finish the day."
"A-Class remote buttons worn out on an older model within their year limit. Repaired for much less than a dealer replacement."
Mercedes-Benz Key Replacement Questions
Straight answers to what Mercedes-Benz owners ask us most about keys, fobs and pricing.
Can you replace a lost Mercedes-Benz key if I have no spare key?
Yes. We replace Mercedes-Benz keys even when every key has been lost or stolen, and the vehicle does not need to be recovered to a dealer. Our technicians read the immobiliser or decode the door lock at your vehicle, cut a new blade to factory specification, and programme the transponder to your Mercedes-Benz so it starts and locks normally.
Which Mercedes years and models do you cover?
We cover Mercedes A-Class up to 2012, B-Class up to 2015, C-Class up to 2014, CL-Class up to 2014, CLK-Class up to 2014, CLS-Class up to 2014, E-Class up to 2014, M-Class up to 2014, S-Class up to 2013, SL/SLS-Class up to 2014, SLK-Class up to 2014, Sprinter up to 2016 and Vito up to 2014. Call 07921 365 247 with your registration and we will confirm whether your year is within coverage.
Do you cover Mercedes Sprinter and Vito keys?
Yes, within our year limits. We cover Sprinter up to 2016 and Vito up to 2014. We come to the depot, yard or roadside so the van does not need recovering to a dealer. Call 07921 365 247 with your registration to confirm your van year is covered.
How long does a Mercedes-Benz key replacement take?
Most Mercedes-Benz key replacements are cut and programmed on-site within 30 to 60 minutes of our technician arriving. A spare key is quicker than an all-keys-lost job, because when every key is missing the vehicle's immobiliser or door lock has to be read before a new key can be created.
How much does a Mercedes-Benz key replacement cost?
You are given a fixed price before any work begins and there is no call-out fee. The cost depends on your Mercedes-Benz model, its year, and whether you need a basic transponder key or a remote fob. Getting a spare while you still hold a working key is always cheaper than an all-keys-lost replacement. Call 07921 365 247 or use our online quote form for an exact figure.
Which areas do you cover for mobile Mercedes-Benz key replacement?
We cover London, Surrey, Sussex and Kent, 24 hours a day, seven days a week. Our fully equipped vans come to your home, workplace, car park, or roadside, typically reaching you within 25 to 60 minutes depending on your location and the time of day. See the full areas we serve list.
