Mobilio Immobilizer Problem
Summary of the thread
A 2021 Honda Mobilio diesel is experiencing an immobilizer issue at 66,488 km, where the engine either doesn't start or starts briefly before dying, with an error indicating an immobilizer fault. The suspected cause is incorrect key programming. The suggested solution is to have the key reprogrammed by a specialist, which resolved the issue.

Spare key exhibits the same behavior. Is there a way to check the key signal or is a trip to the workshop unavoidable?

In my case, the spare key didn't work either. It turned out the immobilizer module itself needed a reset and key re-programming. Save yourself the headache and take it to a specialist.

Thanks for the advice. Took it to a shop, they reprogrammed the key. Cost me 45€. Runs fine now.

Had a similar issue with my old Opel Astra. Same symptoms, immobilizer light flashing. Did you try the spare key? Could be a faulty transponder in the key itself.
