Problem:
Programmed BMW CAS3+ key with Autel IM508S on bench and comfort access is not working. Customer has 1 existing key and added 2 keys to slots 3 & 4. Any idea?
Solution:
You can only have 2 keys in the system with comfort access.
Only have 2 active comfort access keys at the same time.
You need to erase one of them and put the key in the same slot.
First, you must have comfort access key.
Second, only 2 comfort access key allowed to be programmed on CAS.
Only 2 keys can be ENABLED. You need to disable other keys.
Can be more keys in CAS, no need to erase.
But all others have to be disabled.
