Twingo immobilizer issue

Alright, I'm at my wit's end. My 2023 Renault Twingo (electric engine) is giving me fits. It's got around 158975 km on the clock. The engine either doesn't start at all, or starts for a second then dies. I'm getting an error code, but I suspect it's the immobilizer. Maybe the key signal is faulty? Anyone else had issues with the anti-theft system?

Could be a few things. Is the security light on the dash behaving normally? Does it go out after you insert the key? Have you tried your spare key to rule out a problem with the remote?

The security light flashes constantly. I've only got the one key, unfortunately. Is there a way to check the key's programming myself, or am I stuck taking it to a professional?

Flashing security light usually means the immobilizer isn't recognizing the key. Since you only have one key, it's difficult to diagnose further. The key programming is most likely incorrect. While there are some DIY methods floating around online, messing with the immobilizer can brick your car. Best to take it to someone who knows Renault systems.

Okay, thanks for confirming my fears! I bit the bullet and took it in. Turns out the key needed re-programming, just as you suspected. Cost me 45€, which isn't too bad. Thanks for the advice!
