DS3 Immobilizer Errors

My 2018 Citroen DS3 with a gasoline engine is giving me grief. Keeps throwing immobilizer errors. Engine won't start, or starts then dies. Error memory isn't exactly empty. Any ideas?

I had similar issues with my DS3. Is the anti-theft system light doing anything weird? Was your key signal acting up?

Yeah, the anti-theft light flashes rapidly. Key fob seems fine, though. You think it's just the immobilizer being a pain?

Sounds like it. Honestly, I chased my tail for a week trying to bypass the immobilizer. Best bet is get it to a workshop; probably just needs a re-program.

Cheers. Workshop re-programmed the key; cost me 45€, and now it's running great again.
