Deadbolt

Installing a deadbolt is ideal way to secure your door from burglars. The bolt extends into the strike plate that is on the doorframe when locked, making it more difficult for burglars to gain entry into the door. A single-cylinder deadbolt is activated by a key located on the exterior, and a thumb-turn device located on the interior. Deadbolts are only effective only if it's correctly installed, though.

First, you must determine if the door has a hole that is suitable for a deadbolt, or if you need to bore it out. Mark the position of the hole for the deadbolt on the surface of the door using the template included with your lock installation set. Use your tape measure to determine the height of the deadbolt. Mark this height on the door edge. Use the speedsquare to draw a straight line across the mark you made to mark the bolt hole.

Then, using a power drill, bore through the hole until it is on the opposite side of the door. It may take a while. Then, sand down the hole and along the edge of the door until it is smooth. At this point, it's a good idea to stain or paint your door.

Once the door is ready, remove any screws visible on the deadbolt. This will reveal the front and back assemblies of the deadbolt and also the internal bolt. Then, loosen the bolt and replace it with a new bolt that matches the door hardware. You will need to unscrew the bolt from the setplate. After that, you'll have to chisel the area on the door frame to accommodate the strike plate.

If your strike plate isn't aligned properly it's likely that the previous installer didn't properly mortise it or a weatherstripping popped up and changed the strike's position. To fix this issue, you will need to remortise the strike plate as well as the deadbolt. Close and lock the deadbolt once you have completed this step.

Latch

A latch is a piece of metal that extends into the door jamb to keep it shut. It is operated by a handle or knob on the interior side of the door, or a thumb turn on the outside side of the door. Deadbolts can be used to secure a latch and keep intrusions from breaking through the glass of the door. It also helps protect against the accidental or deliberate closing by children or animals. You can choose to install an entry point with either a single-cylinder or double-cylinder deadbolt depending on the level of security.

Installing a deadbolt is exactly the same as installing a latch but there are some differences. First, measure the setback of the doorjamb by using an instrument to make sure that the new lock will fit. The setback is measured from the edge of the doorjamb up to the middle of the hole for the latch plate. A typical setback is 2 3/8 to 2 3/4 inches. If you have a higher setback, you may have to purchase a more substantial latch from a hardware store or locksmith.

Next, drill a hole for the latch plate in the edge of the doorjamb.

Tape the strike plate in the correct position to ensure it is positioned correctly.

Installing the new strike plate is the last step. This can be accomplished by screwing the new plate over the existing screw holes. Then apply wood putty to cover the old screw holes and the bolt hole that is not used. After the putty is dry then sand it to a smooth finish.

Strike

It is an important part of the overall security of a lock since it helps keep the door shut and offers additional resistance to force or kicking applied to the door. If a door is fitted with an electronic strike, it will be opened only with keys and the control unit that regulates its electrical impulses.

Traditionally the installation of an electric strike required cutting out a portion of the doorjamb to remotely remove the latchbolt of a cylindrical lock from the pocket of the strike. This change can be an inconvenience in regards to the appearance of openings, and it also exposes the keeper mechanism and latchbolt to unauthorized users.

Recently, a variety of electric strike manufacturers have developed a "No Cut" kind of strike that does not require a cutout in order to operate. These strikes have a unique design to allow the latchbolt and keeper to slide into the strike pocket without marring the doorjamb faceplate.

The strike is equipped with an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a reader or controller. The retraction of the keeper and latchbolt causes them to rise on the ramp, locking the door.
