SVAutobiography &Passive entry on most L405 cars. Proximity unlocks, start button works without inserting key. All keyless functions tested before we leave.
Keyless entry/start checksL405 KVM faults are reasonably common after battery jump events or water ingress in the spare wheel well. We diagnose first, then decide between repair or used-KVM adaptation.
KVM module faultsLate L405 cars may have Ultra-Wideband smart keys (more secure, anti-relay-attack). Different programming procedure to early L405. We have the tooling for both.
Late L405 faceliftEvery Range Rover L405 job starts the same way — confirm the platform, read the immobiliser, then programme. We follow the manufacturer-spec procedure every time, and you see the new key working before we leave.
L405 confirmed from registration. Early L405 vs late-facelift UWB-equipped variant identified. Determines tooling.

Covering the full L405 — full-fat Range Rover range. These are the variants we work on most often:
Lost both keys to my L405 Autobiography in Switzerland. DashTech sorted it on my return — couldn't face the Swiss dealer route. Brilliant.
Spare key for my Range Rover — got it second-hand with only one. Quick on the driveway in Guildford. Same OEM smart key as Land Rover would supply.
KVM water damage — wouldn't recognise either key. DashTech diagnosed properly, sourced a used KVM, adapted to my VIN. Saved a huge dealer bill.
