With the template included with the lock installation kit, mark the location of the hole for the deadbolt on the door's surface. Then, you can use your tape measure to determine the height the deadbolt needs to be. Then, mark the high point on the outside of the door. Use the speed square to draw straight lines across the mark you made for the bolt hole.

Latch

A latch is a piece of metal that extends through the doorjamb to secure it shut. It is operated by a knob or handle on the inside of the door or a thumb turn on the exterior side of the door. A latch can be secured using deadbolts to stop thieves from breaking through the glass. It also provides protection from the accidental or deliberate closing of the door by pets or children. You can choose to install an entry point with either a single-cylinder deadbolt, or a double-cylinder deadbolt based on the level you prefer for security.

Installing a latch involves the same steps similar to installing a deadbolt however there are some variations. To ensure that the new lock is compatible first, determine the setback of the doorjamb with an instrument such as a tape measure. The setback is measured from the edge of doorjamb up to the center of hole for the latch plate. A standard setback is 2 3/8 to 2 3/4 inches. If your setback is greater it is possible to purchase an extra-long latch from a hardware or locksmith store.

Then, you'll need to make a hole for a latch plate at the edge of the doorjamb. Use a chisel and cut the mortise of the latch. Make sure that the depth is enough for the faceplate to be in line with the doorjamb. Tape the strike plate in place to make sure it is positioned correctly.

Strike

The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is an essential component of the lock's overall security, as it prevents the door from opening and gives an additional level of resistance to force or kick. If a door has been equipped with an electric strike, it can only be opened with keys or the control unit that governs its electrical impulses.

Traditionally the installation of an electric strike involved cutting a small portion of the doorjamb to remotely release a cylindrical lock's latchbolt from the pocket of the strike. This modification is not just undesirable, but also exposes the latchbolt mechanism and keeper to unauthorized users.

Recently, a number of electric strike manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout for operation. The strikes use 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 raises the latchbolt and keeper whenever it receives an electrical impulse from a reader or controller. The latchbolt and keeper are lifted higher on the ramp thanks to the retraction. When the door is closed the deadbolt remains in place and the latchbolt is retracted into the keeper.

Also, you must ensure that the strike is properly connected to your access-control system and is configured to function in a safe manner.

Upgrade your strike plates to high duty strike plates to stop unauthorised entry. These plates use up to six screws of three inches instead of two screws of three-fourths inch. These screws are longer and make breaking the frame to reach the thumb turn piece on a single cylinder deadbolt more difficult.
