Terry Shirley has a deadbolt lock in his Asheboro, NC  home that's hard to turn. Here's his story and he's sticking to it:

"I have a sticky deadbolt on my front door and I know it's not the catch plate, because it's sticky with the door open.

I have tried WD-40 and graphite. Neither worked.

I have also watched your videos on the subject. Short of calling a locksmith, I don't know what else to do. Is there any hope for me to fix this myself?"

Here's my answer:

Terry, good news! There's a great chance you can fix this yourself.

When a deadbolt is hard to turn as you describe and it's not even near the striker plate in the door jamb, it's almost always an issue of the two holes that were drilled in the door.

It's usually easy to remove the deadbolt from the door. That's what you need to do to diagnose the problem.

On the inside of the door, there may be two screws in the face of the deadbolt that will allow you to disengage the lock from the latch mechanism. On the edge of the door you'll see the two screws that hold the latch in. You can't remove the latch until you take the two halves of the deadbolt off the door.

Once the lock is off the door, put it back together as best you can. What you want to do is have a helper hold it while you try to operate it. If it moves smoothly, then you know it's the holes in the door.

Look at the image here to see what you'll have once you remove the parts and reassemble them.

You should start with the smaller hole in the edge of the door. Ninety-five percent of the time this hole is causing the binding. You may just have to enlarge it a very small amount to get the latch to go back and forth with ease.
