SERMI Accredited Locksmith in Kettering
Matt is a fully SERMI accredited auto locksmith — one of very few in the East Midlands. This authorises him to programme replacement keys for the latest BMW, Mercedes, Audi, Land Rover and Volkswagen Group vehicles using manufacturer-level security data. If your locksmith isn't SERMI accredited, they may not be able to do your key at all.
What Is SERMI Accreditation?
SERMI stands for Security-related Repair and Maintenance Information. It's a European scheme, recognised in the UK, that controls who can access the security-related data needed to programme keys and work on the immobiliser systems of modern vehicles.
Since 2022, vehicle manufacturers have been permitted to lock this data behind SERMI authorisation. In practice, that means an independent locksmith can only programme a replacement key for many modern cars if they hold full SERMI accreditation — backed by formal background checks, insurance verification and manufacturer approval.
Matt obtained full SERMI accreditation in 2025, becoming one of the first locksmiths in the UK to do so. For Kettering drivers, that means a genuine local alternative to the main dealer — usually faster, usually cheaper, and carried out at your location.
Without SERMI, Many Modern Keys Simply Can't Be Done
Here's the real-world difference SERMI accreditation makes when you're stuck.
- ✕Can't access manufacturer key data for many post-2022 cars
- ✕All-keys-lost on a modern BMW or Audi often impossible
- ✕Customer forced to recover the car to a main dealer
- ✕Days of waiting and higher dealer costs
- Full access to manufacturer security data
- All-keys-lost handled on-site for the latest models
- No recovery to a dealer — Matt comes to you
- Usually same day, usually cheaper than the dealer
Which Cars Require a SERMI Accredited Locksmith?
SERMI restrictions mainly affect modern European premium and group vehicles. If you drive one of these, you need a SERMI accredited locksmith for key programming on newer models.
How Matt Programmes a Key Under SERMI
A transparent look at exactly what happens when you've lost all keys to a modern vehicle.
Confirm Vehicle & Identity
Matt confirms your vehicle details and ownership — SERMI work requires verified authorisation for security reasons.
Read the ECU / Immobiliser PIN
Using SERMI-authorised manufacturer data via AVDI (Abrites) or Autel IM608 Pro, Matt reads the security PIN from the vehicle's ECU.
Delete Lost Key Codes
All previously coded keys are deleted from the immobiliser so a lost or stolen key can never start the car again.
Cut & Programme New Key
A new key blade is cut and the transponder programmed to the vehicle on-site. You drive away the same visit.
SERMI Is More Than a Badge
SERMI accreditation isn't something a locksmith can simply buy. It requires a current Enhanced DBS check, verified public liability insurance, proof of qualification and ongoing manufacturer approval. It exists to make sure only properly vetted professionals can access vehicle security systems.
That's why SERMI sits alongside Matt's other credentials — and why Leicestershire and Northamptonshire Police trust him for emergency access work.

SERMI (Security-related Repair and Maintenance Information) is a regulated scheme that authorises a locksmith to access manufacturer security data for programming keys and immobilisers. Holding it requires a current DBS check, insurance verification and manufacturer approval — it cannot simply be purchased.
If your vehicle is a post-2022 BMW, Mercedes, Audi, Land Rover, Volkswagen, SEAT, Škoda or Jaguar, key programming often requires SERMI authorisation. For older vehicles and many other makes it may not be needed — Matt will confirm when you call. See our vehicle makes page.
