Answer to: Why won't my Kwikset 6WAL Front Door Lock open?To get it open, you need to slide a sharp knife on top of the bolt. While pulling the door hard enough to prevent the bolt from springing back, use the blade to slide the bolt into the lockset.It will take 2 or 3 turns of the knife to slowly back the bolt into the lockset. By pulling the door tight against the bolt, that should keep the bolt from sliding back into the bolt socket. Eventually, the bolt should clear the strikeplate enough to open the door. It's best to replace the bolt mechanism. It sounds like a worn out mechanism in the latchset.
