Mobile Mercedes-Benz key cutting and programming across West London — FBS3 and the latest FBS4 systems supported on-site. Spare keys from £220, all-keys-lost same day.

Mercedes-Benz key systems are widely considered the toughest in the industry — particularly FBS4 on the latest A-Class, C-Class, GLE and EQS, which most independent locksmiths simply cannot handle. We carry the full AutoTuner and Autel IM608 Pro toolchain along with genuine Mercedes key blanks, transponders and shells in the van. Every model from 2000 onwards is supported on-site at your home, workplace or roadside — typically 40 to 60 percent cheaper than main dealer pricing, with the same dealer-level result.
Real customer vehicles — keys cut and programmed on-site with professional equipment.
