How Our Mercedes Key Replacement and Programming Works
Mercedes immobiliser systems are sophisticated, so the right process and equipment matter. Here’s our step-by-step approach:
-
Assessment
We confirm your vehicle model, year, and symptoms. Common models we support include A-Class, B-Class, C-Class, E-Class, S-Class, GLA, GLC, GLE, GLS, CLA, CLC, CL, SLK/SLC, Vito and Sprinter. We also verify ownership and advise on the fastest solution. -
Non-Destructive Entry (If Locked Out)
Using professional lock-picking and air-wedge tools designed for Mercedes, we attempt non-destructive entry first. Only in rare cases—such as severely damaged locks—might minor invasive techniques be required, and we will explain options before proceeding. -
Key Cutting
We cut laser cut car keys and high-security blades to code using precision key machines for an exact fit. Where needed, we can cut from your existing key, lock, or VIN with appropriate proof. -
Car Key Programming
We use dealer-level diagnostics alongside OBD2 key programming and, when necessary on certain model years, EEPROM/ECU immobiliser programming to match the new key to your car’s security system. This includes smart key programming for keyless start vehicles. -
Testing and Handover
We test remote locking, immobiliser start, boot release and, on vans, sliding-door responses. You’ll receive guidance on battery replacement, key care, and options for a spare.
Our vans carry advanced tools for Mercedes, including:
- Dealer-level diagnostic platforms compatible with Mercedes immobilisers
- OBD2 programmers for transponder and remote key coding
- EEPROM tools for ECU/immobiliser programming on applicable models
- High-precision laser key cutting equipment

FAQs: Mercedes Auto Locksmith North West London
Can you program a Mercedes key without the original?
Yes. We can create and program a new key without the original using dealer-level diagnostics, OBD2, and when required, EEPROM/ECU immobiliser programming. Proof of ownership is required.
How long does Mercedes key replacement take?
Most jobs are completed in a single mobile visit. Time varies by model, year, and whether EEPROM/ECU work is required, but many replacements are done the same day.
Will you damage my Mercedes when unlocking it?
Our vehicle entry is non-destructive wherever possible. On rare occasions where a component is already damaged or inaccessible, we’ll explain options and get your approval before any work.
My Mercedes says “Key Not Detected”. What should I do?
First, try your spare key battery and hold the key near the start button. If it still fails, the key or car’s antenna/immobiliser may need programming or repair. We can diagnose and fix this on-site.
Do you cover Mercedes vans like Sprinter and Vito?
Absolutely. We handle van key replacement, programming, lock and ignition issues, and fleet support across the NW postcode area.
Is it cheaper to use a locksmith than a dealer for Mercedes keys?
In many cases, yes—especially when considering recovery, waiting times, and convenience. Our mobile service comes to you and uses dealer-level tools. For an accurate comparison, request a quote. You can also review our approach to value on our auto locksmith prices in North West London.
