Why Your Car's Make Changes Everything About the Key
Most people assume a car key is just a key. In reality, every modern car key contains an electronic transponder chip — and every manufacturer uses a different chip family, communication protocol and immobiliser system. A Ford key cannot be programmed using BMW tools. A Vauxhall key blank won't fit a Land Rover barrel. The equipment, blanks, software and authorisation required change completely depending on what you drive.
This is why Michael carries make-specific equipment for the vehicles most commonly encountered on Anglesey and Gwynedd — not a one-size-fits-all generic reader. Dealer-level access to manufacturer programming protocols means the key he cuts and programs on site is the same quality as one from the main dealer, at a fraction of the price and with no garage visit required.
The table opposite shows the primary transponder system used by each of the most common makes on Anglesey. Your make's dedicated page gives full model-by-model detail, including which services are available and what equipment Michael uses.
For Mercedes vehicles built from approximately 2019 onwards (FBS4 system), some jobs require dealer-only tools not available to independent locksmiths. Michael confirms compatibility for every Mercedes enquiry before attending — no wasted visits. See also the ECU diagnostics service if warning lights are present alongside a key fault, and the SERMI information page for authorisation requirements on all-keys-lost jobs.

Not every auto locksmith can program every key. The equipment, software access and manufacturer authorisation required to program a BMW CAS module are completely different from those needed for a Ford PATS key. Michael invests in the tools and authorisation for every make he regularly attends.
- SERMI registered — legally authorised to access manufacturer immobiliser and security data. Required for all-keys-lost jobs on most modern makes. See the SERMI information page.
- Dealer-level OBD equipment — reads manufacturer-specific fault codes and accesses immobiliser modules via OBD-II that generic readers cannot reach.
- Make-specific key blanks on board — Michael carries transponder blanks, remote fob housings and blade profiles for all priority makes. Most jobs completed from van stock without ordering parts.
- Fixed price before visiting — confirmed by phone for your specific make, model and fault before Michael sets off. No call-out fee.
- Honest limitations declared upfront — for makes or models where on-site work isn't possible (Mercedes FBS4, some 2024+ models), Michael tells you before visiting — not on arrival.
