Hello can someone help me figure this out I programmed new key's because all key's lost insert them & I get a yellow key symbol with / through it & no starting

Maybe try disconnect / reconnect battery (Note this can cause issue with FRM3 data loss on some cars - but you can fix on bench with HEXPROG if this happens)
If this doesn't work you need to list the procedure you used to make keys so we can see if steps were missed.
Have you made MINI key before successfully?
Is this Flat CAS or Encrypted ?

Thank you for responding & yes I've made a key before successfully the Mini is Cas3 Encrypted I have the Autohex II BMW full & I have the Autel IM 608 programmer I used both separatley on this Mini cooper & both said key's programmed successfully test key but they wouldn't start the car both get the yellow key with / through key symbol

time to post error codes then...

Try battery reset first.
If fault still there scan complete car for codes and post result.

Ok thank you my customer replaced the battery be I made the keys but I'm going back to run a full scan today or tomorrow & will post results

..with such big tools you have key programming should never trouble you like that, especially on a CAS 😊
