How to Increase the Stability of a Deadbolt

A deadbolt strengthens a door because it bolts deep into a vertical post that forms the side of the door. Strengthen the lock with the following method.

You will need

  • Screwdriver
  • Metal pipe
  • Hacksaw
  • Drill with a paddle bit
  • Construction glue

Step 1 Remove the strike plate Using the screwdriver, remove the metal strike plate attached to the doorjamb that the deadbolt slides into.

Step 2 Cut a piece of metal pipe Cut a piece of rigid metal pipe with the hacksaw so that it is about 6 inches long. The diameter of the pipe should be large enough to accommodate the deadbolt.

Step 3 Drill a hole Extend the hole for the deadbolt by drilling through the doorjamb and into the 2-by-4 framing studs that support the wall. Use a paddle bit with the same size outer diameter as the metal pipe.

Step 4 Apply glue Apply construction glue to the inside of the hole.

Step 5 Insert the pipe Insert the metal pipe into the hole until it’s flush with the doorjamb.

Step 6 Reattach the strike plate Screw the strike plate back on. When the deadbolt is fastened, it will now have the additional support of the framing studs.
