How to Secure an Interior Door

A closed door provides security from unwanted intrusion, like a burglar who attempts to enter your home.

Protect Door Edge

To secure an inside door from being forcibly opened, employ different means beforehand to make the door a more formidable barrier. Supplies from a hardware store will be needed, along with tools found in most households.

Open the door. Mount a metal door strip against the inside edge of the door frame facing the door -- use metal screws and a Phillips screwdriver to do this.

Mount a metal door strip against the edge of the door facing the door frame in the same manner as was just done with the door frame.

Close the door. Mount a metal door strip across the bottom of the door using metal screws and a Phillips screwdriver.

Prevent Door Removal

Open the door and make a mark in the door frame facing the back of the door 10 inches down from the top and 10 inches up from the bottom.

Place a mark on the back of the door opposite the marks on the door frame.

Drill a hole in each mark on the door frame with a portable drill.

Mount a locking bolt plate on each mark on the back of the door using wood screws and a Phillips screwdriver.

Close the door so that the extruding bolts on the locking bolt plates go inside the holes on the door frame.

Furniture To Secure Door

Place a metal folding chair against the door.

Rotate the chair so that the seat faces you.

Angle the top of the chair towards the door knob.

Wedge the top of the chair beneath the door knob.

Place a heavy object -- for example, a laundry basket filled with dirty clothes -- against the front legs of the chair.
