Thanks for your reply.

So if a key that was erased from my car is later located, i can copy the key id / remote id of that key from any previously saved key.bin file, and paste it into my current key file, in any of the 10 slots which are unused?

Cause thats what I did, and the key works(starts engine), but the remote unlock/lock does not work, and when i attempt to perform dme cas sync operation, it fails to complete
