Mercedes Key Programming West London — FBS3 & FBS4

Professional. Mobile. Trusted.

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.

  • FBS3 and FBS4 systems both fully supported on-site
  • Spare keys from £220 — programmed on your driveway
  • All-keys-lost recovery without towing to the dealer
  • A, B, C, E, S, CLA, CLS, GL-series, AMG and EQ supported
  • Sprinter, Vito and V-Class commercial keys included
  • 40-60% cheaper than the Mercedes main dealer

Frequently Asked Questions

Which Mercedes-Benz models do you cover?+

Every Mercedes from 2000 onwards — A, B, C, E, S, CLA, CLS, GLA, GLB, GLC, GLE, GLS, G-Wagon, V-Class, Vito, Sprinter, EQ-series and all AMG variants. FBS3 and FBS4 systems supported on-site.

Can you program a Mercedes key without the original?+

Yes — all-keys-lost is fully supported. We read the EIS/EZS data on-site (or via instrument cluster on newer FBS4 cars), cut the blade, calculate the key file and program a brand-new fob on the driveway. Typical turnaround is 90–180 minutes depending on the model.

Do you cover FBS4 (latest A-Class, C-Class, GLE, EQS)?+

Yes — FBS4 systems on the latest Mercedes generation are supported with our up-to-date AutoTuner and Autel toolchain. This is one of the few systems most independent locksmiths cannot do — we can.

How much does a Mercedes spare key cost?+

Spare keys typically start from £220 (older NEC/Infrared) and £280–£450 for FBS3, with FBS4 quoted per case. We confirm a fixed price on WhatsApp once you share the reg and VIN — usually 40–60% cheaper than Mercedes main dealer.

Will the original keys still work after programming a new one?+

Yes — all existing working keys remain active and synchronised. We only disable a key from the immobiliser if you specifically request it (e.g. stolen key scenario).
