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 'key not detected' or 'no key in vehicle' warning has four common root causes: a flat fob battery (especially on cars left for 2+ weeks), a desynced rolling code (common after a flat fob or jump-start), a faulty antenna ring (around the ignition barrel on traditional cars, or behind the dashboard on keyless), or an immobiliser ECU fault (BMW CAS/FEM/BDC, Mercedes FBS3, Audi/VW MQB48, JLR RFA). StageMyCar diagnoses all four kerbside using dealer-grade Autel IM608 Pro, Xtool X100 Pad Elite and AVDI equipment — typical 20–45 minute diagnostic, same-day fix in 95%+ of cases, no tow.
