How to fix a misaligned interior door lock

The lock won't latch because the strike plate is mounted slightly less than a quarter-inch too high. Sloppy work by whoever installed it. If I extend the strike plate indentation and remount it, the new screw holes will be right next to the old ones. Would filling in the old holes with something work?

A solution occurred to me: find some dowel the right diameter and wood-glue it into the old screw holes. I don't know whether or not dowel that size exists. Another idea is to countersink the old wood screws and run them in deep enough to have the strike plate sit over them. Suggestions are welcome.

I often grind the strike plate hole bigger rather than move the strike plate, since moving it not only means holes next to holes but it leaves an ugly mortise to fill and paint.

Good idea but it won't work in this case. I measured the distance between the top of the latch bolt and the opening in the strike plate. It's almost exactly a quarter-inch. Enlarging the opening would run well into the screw hole.

Yes, this is the same way to fix loose hinge screws, assuming you tried the soon to fail tooth pick hack.

Use these 3/8" serrated dowel, you will have to drill the hole out, cut in half, glue them up tap them in flush then the next day your good to drill new holes.

Agree that the wood dowels are the best fix.

Cut in half? Shouldn't I cut them to the exact depth of the drilled-out hole?

You generally just drill a hole, tap them in with glue and then after they are dry, then cut them flush.

Most likly it's a hollow core door so there is only an inch or so of wood around the perimeter so when you drill it goes all the way through so there really is no "depth" to deal with, just tap them in till flush.

That's what I thought. Moving the strike plate up a quarter-inch is easier than moving the doorknob. I have an oscillating tool so I can extend the strike plate indentation, then fill in and paint the gap under it.

The wood screws that were holding the strike plate on are an inch and half so I'll need two of those little wooden dowels for each hole. Fortunately Amazon has a 72-pack for $2.97 so I don't have to go to Home Depot.

I think I have a plan now. Thanks to everyone who responded. Sometimes it's amazing how a little knowledge of how to do your own home repairs can save you a lot of money.

The project is finished. The door locks now, which makes everyone happy because the room it protects is a bathroom with a shower. No one wants other people walking in while it's in use. I just have to spackle and paint around the edges of the strike plate.

Thanks again to those who responded.
