So, I recently purchased a new house and went about changing the locks. The doorknob worked well, but not so much on the deadbolt. Installed everything but one screw which wouldn't budge. I ended up stripping it, but was able to remove it. Since it was the same model as the old deadbolt, I figure the screws on the old one would work. I ended up jamming the screw and now even a stripped screw extractor bit can't move it. Any help would be appreciated.

    Can you post a photo so we can tell which screw is giving you a problem?

    Sometimes, drilling/grinding the head off is the best option available...

    A dremel with a cut off disk can cut a slot that a straight blade screwdriver may be able to back it out.

You can try drilling the head of the screw, which will allow you to remove the cover of th lock and use a vise grip to un-tighten the old screw. Good Luck
