Installing a Deadbolt

One of the finest methods to safeguard your house, property, and the safety of your family is to install a single-cylinder deadbolt lock on your outside doors. Home security professionals and local law enforcement organisations often recommend that homeowners install a lock as an effective barrier against burglars who manipulate entrance doorknobs.

Deadbolts prevent jimmying since the bolt can only be removed from the striking plate by twisting a knob from within the home. Deadbolts feature powerful bolts that reach deep into the door frame as well. It is exceedingly difficult for an attacker to gain entrance to your house via an engaged deadbolt, even with drills, saws, picks, or pry bars, as long as the door frame and strike plate are in excellent condition.

Begin with the first step if this is a new door with no cut-out for a lock.


Stick the Template on the Door.

Look for the paper template needed for drilling holes in the door when packaging the lock. The template might be part of the instruction page or printed on the inside of the product’s box. Unfold the template and use scissors to cut where specified. Using painter’s tape, secure the template to the door. The template is typically draped over two sides of the door: the door face and the door edge.

Drill the Bolt Mechanism Holes

Incorporate the hole saw into the cordless drill. Use a hole saw with a 2 1/8-inch diameter or the size recommended in the instructions. Close the door. Drill the huge hole for the lock mechanism on the face of the door slowly.

Make a hole for the bolt.

Move to the door’s edge. The other part of the template should be still present. This part denotes the location of the second hole in the door—the hole that allows the deadbolt to go in and out.

In the drill, insert the 1-inch spade bit (or the size specified in the instructions). Place the sharp end of the spade bit precisely on the template’s centre dot. Check that the door is supported. Slowly turn on the drill and auger through the paper, then into the door’s wood. Continue augering until this hole reaches the 2 1/8-inch hole made in the previous phase.

Strike Plate and Bolt Chisel Spaces

An inserted metal striking plate supports the door jamb and allows the deadbolt to slide more smoothly. Outline the inset region on the door jamb with the plate and a pencil. Gently chisel down approximately 1/8-inch and cut off the desired area with the chisel and hammer.

A similar inset will be seen on the bolt. Insert the bolt into the 1-inch hole and trace the plate’s shape. Remove the area, then chisel it down to 1/8-inch.

Bolt the Door Jamb Strike Plate into place.

Screw the striking plate to the door jamb with two screws using a Phillips screwdriver and the provided screws. Similarly, put the lock into the 1-inch hole, carefully tap it into the carved-out region, and screw it into place.
