Mercedes B-Class Locksmith Hamilton

The Mercedes-Benz B-Class is a practical compact MPV that has quietly built a loyal following in Hamilton among owners who want Mercedes build quality without the premium-hatch price tag. The W246 generation, built from 2011 through to the 2015 FBS4 changeover, runs the older FBS3 immobiliser — which means most B-Class vehicles on Waikato roads are squarely within what we can service.

“Lost the only key to my Hilux on a Friday afternoon. New key cut and programmed in my driveway by Saturday morning — and it cost half what the dealer quoted. Will absolutely call again.”

Mercedes B-Class Key Systems

W246 (2011–2014, FBS3): EIS transponder key, remote central locking on most NZ trims. This is the bulk of the B-Class population in Hamilton and we program keys for it in full — standard key and remote replacement, all-keys-lost recovery, and lost-key deletion.

W246 from the FBS4 changeover (2015 onward): Later-build W246 models moved onto FBS4, Mercedes' closed system. These need the Mercedes dealer network. We confirm your build date by VIN before quoting so there is no guesswork.

Common B-Class Key Problems in Hamilton

Remote not locking/unlocking: Usually a flat CR2032 battery in the fob — a quick fix we carry the parts for on every job.

All keys lost: EIS OBD recovery for FBS3 W246 models — generates a new key from the vehicle without needing the original.

Worn ignition barrel: On higher-mileage W246s, a key that needs extra wiggling to turn is worth having looked at before it fails completely.
