Mark the location of the hole for the deadbolt on top of the door by using the template supplied with the lock installation set. Use your tape measure to determine the height of the deadbolt. Mark this measurement on the door lock replacement's edge, and then use a speedsquare to draw a straightline across the mark that you made for the bolt hole.

Latch

A latch is a piece metal that extends through the doorjamb to hold it shut. It is operated by a handle or knob on the inside of the door, or a thumb turn on the exterior side of the door. A deadbolt is a device used to secure a latch and stop intrusions from breaking through the glass of the door. It can also protect against the accidental or deliberate closing by animals or children. A latch can be set with single cylinder deadbolts or double cylinder deadbolts, based on the level of security you prefer.

Installing a deadbolt is exactly the same as installing a latch but there are some differences. To make sure that the new lock will fit, first measure the setback on the doorjamb using the tape measure. The setback is the distance between the edge of the doorjamb to the center of the hole that will be used for the latch faceplate. The standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you may need to purchase a more substantial latch at a hardware store or locksmith.

Strike

An electric strike is the metallic part where the deadbolt and latch are engaged when the door is closed. It is an essential part of the lock's overall safety, as it prevents the door from opening and gives an additional barrier to force or kick. If a door is equipped with an electric strike, it can only be opened with a key or the control unit that controls its electrical impulses.

In the past, putting in an electronic strike required cutting a piece of a doorjamb in order to release the latchbolt of a cylindrical lock from the pocket that is inside the strike. This modification is not just ugly, but also exposes the mechanism for the latchbolt and keeper to unauthorized users.

Recently, a number of electric strike manufacturers have developed a brand new electric strike dubbed the "No Cut" strike that doesn't require an opening in the doorjamb to operate. They use a specific design that allows the latchbolt and keeper to slide into the pocket without damaging the faceplate of the doorjamb.

The strike is equipped with an internal ramp that lifts the latchbolt and keeper whenever it receives the signal of the reader.
