BMW X4 Locksmith Hamilton

X4 F26 (2014–2018): The first-generation X4 runs BMW's CAS4/FEM key system, shared with the F25 X3 of the same era. Comfort Access is standard on most NZ trims. All-keys-lost recovery depends on whether your specific build has CAS4 (usually an OBD write) or FEM (a module bench read in the van) — we confirm which before travelling.

X4 G02 (2018–present): Current generation uses BDC, BMW's most integrated body/key architecture. Falls mostly outside our coverage window; see the FAQ below on the 2021-onward cutoff.

Comfort Access fob battery failure: The most common X4 callout — a flat CR2032 causes intermittent proximity detection. We carry the correct cell and re-pair on site.

All keys lost: Genuinely urgent for an X4 owner with no spare. We attend across Hamilton and the Waikato and complete the job at your vehicle — no towing.

A Hamilton East owner locked their only Comfort Access key inside the X4 along with their phone after a gym session — the fob's proximity function wouldn't override the lock from outside.

We arrived within 30 minutes, got the vehicle open without any damage to the paint or trim, and confirmed the key and battery were both fine — no programming needed, just entry. Total time on site: 15 minutes.
