I didn't understand what you mean, the main deadbolt of the anti-theft door is locked and unlocked with a key, the main deadbolt is divided into two (rotating) completely open or closed, first try to see if the key is flexible under the condition of the door open, if it is flexible, it means that the position of the door frame and the deadbolt is deviated, and the problem needs to be found. If it is not flexible when it is opened, it should be that there is a problem with the lock, and you can remove it and reinstall it to see if it can be solved.
