Wot a bummer!
Bet your missus ain't happy.
Can't see how having a bust key can have done this.
Did it accidentally short summat in/under the steering column or near the ignition switch?
If it won't start I'd a thort even a normal old skool OBD11 reader would have told you.
I suppose you have already checked all the fuses and relays, and that the batt is fully charged?
Maybe time to join a MINI forum?
(I had to with the Pluriel)

Ive got the following of the diagnostics......I will have a look at mini forums, she aint pleased and now
just asked me to go & get her a car. Battery fully charged all fuses ect all good I also had the jump leeds
on it to see if its a low voltage thing but battery was 12.64v with a starting capacity of 87%.

Looks like batt's OK then.
So it's looking for key 2, key three has gone missing and you have keys 4 and 5.
Does it just need telling to look for either key 4 or key 5 or either? Maybe it needs to be told to cancel key 2 or summat?
I REELY don't know, feckin electrickery, and I suspect they are all different. But I did suspect it would need some friggin around through diagnostics to make the ffin car recognisse the ffin key.
I know that BMW garages charge a king's ransom per hour, but it might be worth giving em a ring?
I do know you are fast getting into the realms of paying more for this than you paid for the car.:mad::mad::mad:
You need the equivalent of sierrafery on a BMW/MINI forum.:rolleyes:
i'm having a look to see if i can find anything that might halep, but I expect you have already done this.
so bear with me as I chuck links at you, some more specific than others.
course I don't know what year the car is or if the MINI Cooper is different in any way when it comes tyo keys than the more ornery MINI
