How Mercedes Key Replacement and Programming Works
We bring the workshop to you. Our process is designed to get you moving again with minimal hassle:
- Diagnose and verify
- We confirm the fault: lost key, fob not responding, no start, or lockout.
- We run OBD2 diagnostics to check immobiliser data, steering lock status, and key recognition. For some models, EEPROM/ECU work may be required, which we carry out carefully with specialist tools.
- Non-destructive entry wherever possible
- If you’re locked out, we use non-destructive entry techniques to open the vehicle without damage. In rare cases where drilling or component removal is unavoidable (for example, failed locks or damaged ELV/ESL units), we explain the reasons clearly and get your approval before proceeding.
- Key cutting and coding
- We cut laser/high-security key blades to OEM specification and then pair the key or fob to your Mercedes immobiliser system using dealer-level equipment.
- For smart/proximity keys, we perform smart key programming and Keyless-Go synchronisation, ensuring both remote and start functions work correctly.
- Final checks and handover
- We test remote locking/unlocking, emergency blade operation, and engine start.
- We provide guidance on caring for your keys and back everything with our workmanship guarantee and key warranties where applicable.

FAQs: Mercedes-Benz Keys And Locks
Can you replace a lost Mercedes key without the original?
Yes. We can create and program a new key without the original by accessing your Mercedes immobiliser data via OBD2, and when necessary through EEPROM/ECU methods. We’ll verify ownership first and complete key coding on-site.
My Mercedes says “Key Not Detected.” What should I do?
First, try a fresh key fob battery and use the emergency start position (often the key slot or a marked area on the steering column/console). If it still won’t start, the transponder or smart key pairing may have failed. We can test and re-synchronise or program a new key if required.
Can you program Mercedes smart keys and Keyless-Go fobs?
Yes. We offer smart key programming and Keyless-Go synchronisation for many Mercedes models. Our dealer-level tools allow us to add or replace keys, and we’ll test remote and start functions before handover.
Do you provide non-destructive entry for Mercedes lockouts?
Wherever possible, yes. We use specialist tools and techniques to open your Mercedes without damage. If a component has failed and non-destructive entry isn’t feasible, we’ll explain your options and get approval before any invasive work.
How long does Mercedes key replacement take?
It varies by model and system. Standard jobs can be completed the same visit, often within an appointment window on the day. More complex cases involving EEPROM/ECU work can take longer, but we’ll advise you clearly before starting.
Can you disable a lost or stolen Mercedes key?
On supported systems, we can erase lost keys from the vehicle’s memory and program new ones, helping to protect your car from unauthorised use.
