Keyfirst holds an exclusive contract with OBDSTAR as well as with OBDSTAR UK, the result of a trusted partnership for more than 20 years.

Unlike some competitors, OBDSTAR develops its own solutions on its own servers, guaranteeing continuous monitoring, no risk of blocking, and full service continuity.

OBDSTAR is a globally recognised leader in diagnostics and key programming. Its tools are praised for reliability, speed, and multi‑brand compatibility. Today, more than 1,300 UK professionals already use the G3, chosen by major national auto‑centre chains. The X300 Classic Key Master G3 has therefore become the reference tool in the UK for key programming and IMMO.
