Installing a new lock is a relatively straightforward task that can be completed by most homeowners with the proper tools and some basic knowledge. Here is a step-by-step guide to installing a deadbolt lock:
You will need the following tools and materials:
Determine the location where you want to install the deadbolt lock. It is typically installed on the door frame, about 36 inches above the floor.
Using the hole saw, drill a hole through the door frame that is slightly larger than the diameter of the deadbolt.
Using the chisel and hammer, create a mortise in the door frame that is wide enough to accommodate the lock body.
Insert the lock body into the mortise and secure it with screws.
On the door jamb, mark the location where the strike plate will be installed. Drill three pilot holes and secure the strike plate with screws.
Insert the key into the lock and turn it. The deadbolt should extend and retract smoothly.
