I've encountered this twice in the last two days. First, I came back from a looting trip and tried to unlock the door to my base with a lockpick after having locked it, but would not give me the option to unlock. It gave me the option to lock the door, or to open. The open option did not work, the door only rattled. The lock option also did not work, as the button would not hold for the duration of time needed to lock the door, it would hold for a second and then stop, since the door was already locked. I relogged, which did not solve the problem, but I walked away and came back and it finally let me unlock the door.
Just now, I logged in again after being away all night. I am inside my base and having the same issue. The door will not unlock, and gives me the same options, "Press 'X' to open", or "Hold 'RT' to lock" even though the door is locked and I cannot open it.
