Professional. Mobile. Trusted.
Mercedes-Benz key systems are widely considered the toughest in the industry — particularly FBS3 on the pre-2015 C-Class, E-Class, S-Class and GLC, 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. Pre-2015 FBS3 models are 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. Post-2014 FBS4 (EQ EV, most W205/W213/W222/W447/W167/W907) is dealer-only; we don't quote for it.

Frequently Asked Questions
Which Mercedes-Benz models do you cover?+
Pre-2015 FBS3 Mercedes only — A, B, C, E, S, CLA, CLS, GLA, GLB, GLC, GLE, GLS, G-Wagon, V-Class, Vito, Sprinter (up to the FBS4 switch) and AMG variants built before 2015. Post-2014 FBS4 (EQ-series, most W205/W213/W222/W447/W167/W907) is dealer-only.
Can you program a Mercedes key without the original?+
Yes — all-keys-lost is fully supported for pre-2015 FBS3. We read the EIS/EZS data on-site, 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.
Can you handle FBS3 on site?+
Yes — pre-2015 FBS3 systems are supported with our AutoTuner and Autel toolchain. Post-2014 FBS4 is dealer-only — we don't quote for it.
How much does a Mercedes spare key cost?+
Spare keys typically start from £220 (older NEC/Infrared) and £280–£450 for FBS3. 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).
