Today I was unable to turn the key to the left when inside the lock to unlock the doors. The key wil not turn to the left. It will oddly turn to the right and I can lock the doors but not unlock them. I oiled the lock and actually I had oiled it about 3 weeks ago so I am surprised I am having this issue. Has anyone run into this problem? It feels like a mechanical issue as I don't think there's any electronics that would prevent the key from turning left, correct?
