When You Need A Mercedes-Benz Auto Locksmith
Mercedes owners contact us for a wide range of problems. Typical scenarios include:
- Lost or stolen Mercedes keys and needing a secure replacement
- Key fob not responding or intermittent central locking faults
- Proximity key or push‑button start not detected by the vehicle
- Broken key blade, snapped key, or key stuck in the ignition
- Damaged key after a collision or water exposure
- Old key requires reprogramming or replacement after battery changes
We work with all Mercedes models, including A‑Class, C‑Class, E‑Class, S‑Class, GLA/GLC/GLE SUVs, Vito and Sprinter vans, and the latest EQ electric range. Our technicians understand Mercedes‑Benz immobiliser systems and common model‑specific faults so we can diagnose and resolve issues without sending you to a dealer in many cases.
How We Help — Professional, Non‑Destructive Where Possible
We follow a clear, step‑by‑step approach tailored to Mercedes vehicles:
- Rapid assessment on the phone to understand the problem and confirm vehicle details and location.
- Mobile visit across Kingston upon Thames and the KT postcode area using fully equipped vans carrying laser‑cut key blanks, transponder chips, key shells and battery stock.
- Advanced diagnostics and programming using dealer‑level diagnostic tools, OBD2 key programming, EEPROM/ECU access where required, and specialist Mercedes programming equipment.
- Non‑destructive entry where possible—our technicians use air wedges, slimline unlocking tools and vehicle manufacturer‑approved methods to avoid damage. If a non‑destructive solution is not possible, we explain options and costs before any work begins.
- Key cutting, transponder/chip programming and full immobiliser synchronisation so your new or replacement Mercedes key works exactly like the original.
We routinely use dealer‑level diagnostics and tools such as OBD2 programmers and EEPROM/ECU interfaces for complex programmes. This allows us to perform tasks that previously required a main dealer visit — for example, adding new keys to a Mercedes security system or reprogramming a proximity key after a battery replacement.

FAQs
Can you make a new Mercedes key without the original?
Yes. We can create and programme a new Mercedes key without the original in most cases using OBD2/EEPROM programming and secure key erasure where required. Vehicle proof of ownership is required for security reasons.
How long does Mercedes key programming take?
Simple battery replacements and reprogramming can take 20–45 minutes. Creating a new key from scratch typically takes longer depending on the model and whether ECU access or key synchronization is needed; we’ll give a time estimate after inspection.
Will you damage my car to gain entry?
No—wherever possible we use non‑destructive entry techniques. In rare cases a damaged lock barrel may require replacement; we will discuss this fully with you before proceeding.
Do you offer a warranty on Mercedes keys and programming?
Yes. We provide a warranty on workmanship and keys/programming. We also carry public liability insurance and our technicians are DBS checked.
Can you programme Mercedes proximity keys for late model vehicles?
Yes. We have dealer‑level equipment and experience with modern proximity and push‑to‑start systems. Some late model Mercedes may require additional dealer parts; we’ll explain this during diagnosis.
