Hello

Tried to program keys with autel when going by procedure immo sign gets of on dash but as soon you finish programming and turn ignition n same sign there.
What other options are to program keys?

maybe this old thread will help https://www.digital-kaos.co.uk/forum...cra-2004-P1611 i suspect there will be many more threads on this on the forum , the search function will find and list them so you can view how other members have solved this issue.

this fault is common after low voltage cranking or changing of parts , check fuses and relays , try battery reset , delete fault codes in ecm and all modules . reinitialise ecm and nats.

of course you dont know if the customer has caused other issues when changing battery , cross polarity , changing battery with ignition switched on etc , may have corrupted something or blown some fuses.

Try this always works for me, switch ignition on remove either battery terminal and live ignition on for 2min while battery off, replace battery terminal start vehicle from where you left ignition on tell us the good news.
