Using the template that comes with your lock installation kit, mark the location of the hole for the deadbolt on the door's surface. Use a tape measure to determine the height of the deadbolt. Then, mark this height on the edge of the door. You can then use a speed square to draw an even line across the mark you made for the bolt hole.

Latch

A latch is a metal piece that extends into the doorjamb to keep it closed. It is operated with a knob or handle on the inside of the door or a thumb turn on the exterior side of the door. Deadbolts can be used to secure a latch and prevent intrusions from breaking through the glass of the door. It also offers protection from the accidental or deliberate closing of the door by pets or children. You can install a latch with either a single-cylinder or double-cylinder deadbolt, depending on your preferred level of security.

Installing a latch follows the same steps similar to installing a deadbolt however there are some differences. First, measure the setback of the doorjamb with an instrument to make sure that the new lock will fit. The setback is the distance between the edge of the doorjamb to the middle of the hole that will be used for the latch faceplate. A typical setback is 2 3/8 to 2 3/4 inches. If you have a higher setback, you might need to purchase a larger latch at a hardware store or locksmith.

Strike

An electric strike is a metal part where the deadbolt and latch engage when the door is closed. It is a vital component of the security of a lock, because it seals the door and provides extra resistance to force or kicks applied to the door. If a door has been equipped with an electric strike, it can be opened using a key or the control unit that governs its electrical impulses.

In the past, putting in an electronic strike required cutting off a part of a doorjamb, which would release the latchbolt of a cylindrical lock from the pocket inside the strike. This modification is not only undesirable, but also exposes the mechanism of the latchbolt and keeper to unauthorized users.

Recently, several electric strikes manufacturers have created a "No Cut" type of strike that doesn't require a cutout to operate. These strikes have a unique design that allows the latchbolt and keeper to slide into the strike pocket without marring the doorjamb faceplate.

The strike has an internal ramp that lifts the latchbolt and keeper when it receives an electrical impulse from a reader or controller. The retracting of the keeper and latchbolt raises them on the ramp, thereby locking the door. When the door is closed, the deadbolt remains retracted, and the latchbolt retracts into the keeper.

Installing an electric strike is a simple process, especially when you are replacing the strike on a previous door. If, however, you are upgrading to an electric strike for an access control system, you'll be required to ensure that the new system is compatible with the kind of lock you've installed. Also, you must ensure that the strike is properly connected to your access control system and that it is configured for fail-safe operation.

Upgrade your strike plates to high duty strike plates to stop unauthorized entry. These plates are fitted with four to six three-inch screws instead of the two three-fourth inch screws typically used in standard strikes. The longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt for a cylinder more difficult.
