Best automotive key programmers

Top pick: Autel MaxiIM IM608 Pro II — the closest thing to a do-everything shop tool: reads, writes and programs keys and immobilizers across a huge range of makes, with a big touchscreen and Android interface that make guided jobs easy to follow. It's the one to buy if you're doing this for money.

Who the others suit:

• Autel IM508S — same Autel ecosystem and coverage, smaller screen and lighter on the wallet; the sensible step down for a part-time locksmith.
• Lonsdor K518 PRO (full version) — all-in-one coverage with a big battery; a good alternative if you work on a lot of Asian and European models.
• Xhorse VVDI Key Tool MAX PRO — remote/key generation and cloning rather than full vehicle programming; ideal as a second tool beside a programmer.
• Autel MaxiIM KM100 — quick universal key generation for common makes; great starter kit.
• Budget OBD dongles (Auto Key Max Pro, POPLIS X431, Falleo V87) — fine for simple self-pairing on older, basic keys; expect thin coverage and little support.

Check the coverage list for the exact makes and years you work on before buying — that matters more than any spec.
