Mini Countryman immobilizer issue

Ugh, my 2020 Mini Countryman is being a total pain. Won't start! Sometimes it'll fire up for a sec and then dies. Error memory's showing something about the immobilizer. Think the key's gone wonky somehow?

A 2020 Mini Countryman was experiencing starting issues, with the engine dying shortly after ignition and an error memory indicating an immobilizer fault. The problem was suspected to be related to the key's coded signal, possibly due to a malfunctioning chip. The solution involved checking and reprogramming the key, which resolved the issue.

Did this summary help you solve your problem?

I had a similar issue with my Countryman. It sounds like an immobilizer fault. The immobilizer is part of the car's anti-theft system. It uses a coded signal to verify that the correct key is in the ignition. If the signal is wrong or missing, the ignition control is disabled and the car won't start. Was the error memory read and the immobilizer fault confirmed?

Error memory was indeed read and it showed an immobilizer fault. When you say 'coded signal', do you mean like, the chip in the key is messed up or something?

Yes, the coded signal comes from a chip in the key. If the car electronics can't read it properly, due to damage or a programming error, it can cause an immobilizer fault and prevent the engine from starting. It is best to visit the workshop.

Dude, you nailed it. Got the programming on the key checked and boom, fixed. All in, 45€! Thanks a million!
