So basically you're saying one of the two keys still remains correct? And 1 of the 2 original keys programmed to car remains so you Want to program that so the other key is locked out correct?
If this is the case "All Keys Lost" sounds like the way to go unless there's a way to go into the menu and delete each key individually then if so you could just delete the key that's missing.
I state it this way as some are viewing it differently.
Myself I have some keys, 2 given to me by 2 different customers from vehicles they had totalled out. One is from a Hyundai and one a Jeep. I know they need to be unlocked so I need to figure out how.
