Key fob failures and immobiliser faults sit between mechanical and electronic — most are battery, signal or coding issues rather than a 'broken' key. Drova diagnoses on your driveway, programs replacement fobs and resets immobiliser codes for most makes.
If the car cranks but won't fire and the immobiliser/key symbol stays on the dash, the key isn't being recognised. If the central locking doesn't respond to the fob, the fob battery, the transmitter or the body control module is the culprit.
Drova programs key fobs and immobiliser resets for Ford, Vauxhall, VW group, BMW, Mercedes and most Japanese makes. Some premium and Stellantis models need main-dealer access — we'll tell you straight when that's the case.
Diagnostic & fob battery — £49 · Key re-pair from £79. New replacement key with programming from £140 (transponder-only) to £290 (full proximity fob). Dealer-only jobs identified before any charge.
The immobiliser isn't recognising the key. Most common causes: a flat fob battery (replace it and try), a key that's lost its pairing (re-pair on the OBD port), or a failing key transponder (program a new one). All diagnosable in 30 minutes on the driveway.
Yes — for most Ford, Vauxhall, VW, BMW, Mercedes and Japanese cars. Some premium and Stellantis models are still dealer-only and we'll tell you straight.
Usually a flat fob battery (£5 fix) or a worn transmitter (£25 shell). Drova confirms in 5 minutes before quoting anything bigger.
Aftermarket transponder-only keys from £140 programmed. Proximity / keyless fobs £190-£290 fitted. Always cheaper than the main dealer.
