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.
Step 1: Remove the strike plate Using the screwdriver, remove the metal strike plate attached to the doorjamb that the deadbolt slides into.
TIP: The doorjamb is the vertical post that forms the side of the door. The doorjamb is the vertical post that forms the side of the door.
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.
TIP: Make sure the hole is aligned with the deadbolt. Otherwise you will have to adjust the door later.
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.
FACT: Crime prevention experts recommend that all exterior doors in your home be equipped with deadbolt locks.
