How we handle london-wide · pre-2015 fbs3 · ir · smart key · sprinter
StageMyCar covers every London postcode for pre-2015 FBS3 Mercedes key replacement — IR keys on older W203, W211, W164 and W639 Vito (£240-£320), and early smart keys on W204, W212 and W221 before the FBS4 switch (£320-£480). Post-2014 FBS4 platforms (most W205, W213, W222, W447, W167, EQ EV and current AMG) are dealer-only — we don't take those jobs. Dealer pricing in London routinely exceeds £600-£950. We attend driveways in Hampstead, underground bays in Mayfair, City of London office car parks, Canary Wharf reserved bays, and every postcode from W1 to NW10. Engineers carry dealer-grade FBS3 hardware and OEM-spec blanks for the pre-2015 generation.
