When You Need A Mercedes Auto Locksmith
Mercedes vehicles use advanced immobiliser and key systems. When something goes wrong, it’s stressful—especially if you’re stranded. Common scenarios we help with include:
- Lost or stolen Mercedes keys and urgent key replacement
- Locked keys in the car or boot, including estate and SUV tailgates
- Key fob not responding, intermittent locking, or no start
- Key won’t turn or “Key Not Detected” on push-to-start models
- Broken or snapped key blades and worn keys that won’t operate locks
- Faults after a battery change or jump-start, including steering lock or ESL issues
- Ignition and lock problems on older models and commercial vans
If your situation sounds familiar, our team can advise quickly and usually resolve it on the spot. For specific lost or theft situations, see our guidance on lost or stolen car keys.
Mercedes Models We Regularly Support
We work with most Mercedes-Benz passenger and commercial vehicles, including:
- A-Class, B-Class, C-Class, E-Class, S-Class, CLA, CLS
- GLA, GLB, GLC, GLE, GLS, G-Class
- SLK/SLC, SL, AMG variants

How Our Mercedes Key Services Work
We use dealer-level equipment and processes tailored to Mercedes-Benz systems to keep your vehicle secure and get you moving efficiently.
-
Diagnostics and security access
- We connect via OBD2 to read immobiliser/ECU data and confirm the correct path (key programming, ESL reset, or module adaptation).
- For some models and situations, we may use EEPROM techniques to extract data directly from the immobiliser or ECU. This is common where OBD access is restricted or modules are locked.
-
Mercedes key replacement and programming
- Lost all keys: We can create new keys from scratch, pair them with your immobiliser, and synchronise remote locking. Where required, we’ll disable missing keys to protect your vehicle.
- Spare keys: We cut and program additional keys (remote or smart/proximity) so you’re covered in future.
- Smart key programming: For push-to-start vehicles, we match a new key to your car’s immobiliser and perform any necessary personalisation and coding steps.
-
Key fob repair and restoration
- Replacement housings, key blade replacement, and battery service
- Repair of worn buttons and re-soldering of damaged components where viable
- Full key fob replacement when repair isn’t reliable
-
Non-destructive vehicle unlocking
- Locked out? We use specialist tools and techniques to gain entry without damage wherever possible. We’ll explain any rare exceptions (e.g., severely damaged locks) before work begins.
-
Lock and ignition support
- Car lock repair, rekeying to new keys when necessary, and alignment fixes
- Ignition and steering lock (ESL) diagnosis and repair on applicable models
- Advice on common Mercedes steering lock faults and safe remedies

FAQs: Mercedes-Benz Auto Locksmith Twickenham
Can you replace a lost Mercedes key without the original?
Yes. We can create a new Mercedes key without the original by accessing immobiliser data through OBD2 or, where necessary, EEPROM methods. We then program the new key and can deactivate lost keys to protect your car.
Will you damage my Mercedes when unlocking it?
We use non-destructive entry techniques wherever possible. In very rare situations—such as severely damaged locks—we’ll explain the options and get your approval before any work that risks minor cosmetic impact.
Can you program smart keys and keyless entry fobs for Mercedes?
Absolutely. We handle smart key programming for most Mercedes models, synchronising remote locking and the immobiliser so push-to-start works as intended.
My Mercedes shows “Key Not Detected”. What should I do?
Check the key battery first. If the message persists, it could be a key fault, antenna/receiver issue, or immobiliser sync problem. We can diagnose on-site and resolve with key programming, repairs, or module adaptation as required.
Do you cover Mercedes vans like Vito and Sprinter?
Yes. We support Vito, V-Class and Sprinter fleets, including spare keys, lost key situations, vehicle unlocking, and door/ignition lock repairs for commercial users.
How long does Mercedes key replacement take?
In many cases, we can supply, cut, and program a key during a single visit. Exact timing varies by model and whether all keys are lost, but our mobile service avoids dealer wait times.
Is your team insured and checked?
Yes. We hold public liability insurance, and all technicians are DBS-checked. We also provide warranties on workmanship and keys we supply.
