Mini Roadster immobilizer problem

My 2014 Mini Roadster is presenting an immobilizer problem. The engine either doesn't start at all, or it starts briefly and then cuts out. There's an error stored in the error memory pointing towards this immobilizer fault. From what I've gathered, the most likely cause is an incorrect key programming. Has anyone experienced something similar, and what steps did you take to resolve it? I'm not looking for an immobilizer bypass solution.

I had a similar issue with my Mini Roadster some time ago. The security light was flashing, and the engine would start for a second then cut out. The car immobilizer seemed to be the culprit. Did you check the error codes? It might give you a clue. It's like a digital handshake failing between the key and the car.

The error memory does point towards an immobilizer fault. You mentioned the security light flashing; was that the only symptom you experienced, or were there any other telltale signs before the car refused to start properly?

Yes, the flashing security light was the main symptom before it completely refused to start. If the error memory indicates an immobilizer fault and you suspect key programming, it might be best to take it to a workshop with the necessary diagnostic equipment. They can confirm the key's programming and reprogram it if necessary. Hopefully, it's a simple fix.

Just an update: it was indeed a programming issue with the key, like a software glitch. A quick re-programming at the workshop and 45€ later, and the Mini Roadster is back on the road. Thanks for the advice; it pointed me in the right direction.
