Hello team, I am about to change my BCM - I know it need to be a compatible code, key change etc, when I purchased the car it came with one key, I purchased a second key that learnt the code for the current BCM. Can this same key relearn the code for the replacement BCM or is it a case of once it learns a code that is it and it cant be changed.

Checking the s/h market it would appear BCM's for all cars die on a regular basis, does any smart IT person repair them?
