Locked out at 11pm near Heathrow. They were with me in 25 minutes, no damage, cheaper than the dealer quoted. Genuine lifesavers.

Professional. Mobile. Trusted.
A replacement car key in 2026 typically costs between £120 and £550 depending on what you've lost and what you drive. A spare key for a Ford, Vauxhall or Toyota is usually £120–£200. A lost-key replacement (where the original is gone but a spare exists) sits at £180–£300 on most volume brands. All-keys-lost — where every key is missing — runs £250–£550 because the immobiliser has to be reset, and on prestige (BMW CAS4/FEM/BDC, Mercedes FBS4, JLR RFA, Porsche, Bentley) it can reach £950. StageMyCar carries every transponder, cuts to code, and programs on your driveway — same OEM-spec part as the dealer at typically 50–70% less, same day, no tow. Every quote is fixed, fully inclusive of VAT, and agreed before we attend.
