Why SERMI Registration Matters for Modern Car Keys
SERMI stands for Security-related Repair and Maintenance Information. In simple terms, it is a secure authorisation framework used by independent operators who need access to security-sensitive vehicle information for certain types of repair work.
For drivers, this matters because many modern vehicles cannot be handled like old mechanical keys. Lost key replacement, transponder programming, immobiliser work and some remote key procedures may require controlled access to manufacturer security data or functions.
Michael is SERMI registered, DBS checked and fully insured, so customers across Anglesey and Gwynedd can call one local mobile auto locksmith instead of automatically being forced toward a dealer.
Important: SERMI registration supports security-related work, but it does not guarantee every vehicle can be programmed. Some systems, such as certain Mercedes FBS4 security systems, may remain dealer-only. Michael will confirm what is possible before attending.
In plain English, SERMI helps with:
- 1
Secure access
Controlled access to security-related repair information where a manufacturer or scheme requires authorisation.
- 2
Customer protection
Security checks, proof of ownership and proper record keeping help prevent vehicle theft and misuse.
- 3
Professional key programming
Transponder, immobiliser and remote key jobs can be handled using the correct route instead of guesswork.
- 4
Better independent repair access
Independent auto locksmiths can support customers without every security-related key job going straight to a dealer.

Vehicle Entry →Why Michael Checks Proof Before Security Key Work
When a job involves opening a vehicle, programming a key, deleting lost keys or accessing immobiliser functions, Michael may need to confirm that you are the owner or authorised user of the vehicle.
This is not to make the process difficult. It protects the customer, the vehicle and the locksmith. It is also part of working responsibly around modern vehicle security systems.
- ✓
Vehicle proof
V5C logbook, insurance document, hire/lease agreement or another document linking you to the vehicle.
- ✓
Personal ID
Driving licence or another form of identification may be requested before security-sensitive work.
- ✓
Vehicle registration
Have the registration number ready when you call so Michael can check compatibility before attending.
What if the documents are locked inside?
If your V5C, insurance or ID is inside the locked vehicle, call Michael and explain the situation. He will advise what is possible for your specific case.
For simple vehicle entry, the proof process may differ from a full lost-key or programming job. For lost all keys, proof of ownership is especially important because new keys and immobiliser access may be involved.
Security-first approach: Michael will not complete security-sensitive work where ownership or authorisation cannot be reasonably confirmed.
Security Key Work for Common Makes
Michael works on the common makes found across Anglesey and Gwynedd. Call with the vehicle registration and issue so he can confirm the exact key, transponder or immobiliser procedure.
Mercedes note: some FBS4 systems are dealer-only for all locksmiths. Michael will be honest before attending if your vehicle falls into a restricted category.
