Latch
A latch is a piece of metal that extends into the doorjamb to hold it shut. The latch can be operated by a knob or handle located inside the door, or by a thumb-turn on the outside.

You can install a latch with either a single-cylinder or double-cylinder deadbolt, depending on the level you prefer for security.
Installing a deadbolt can be the same as installing a latch however there are some differences. First, determine the setback of the doorjamb by using a tape measure to be sure that the new lock will fit. The setback is the distance from the edge of the doorjamb to the center of the hole that will be used for the latch faceplate. A standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you may need to purchase a longer latch from a hardware store or locksmith.

If a door comes with an electronic strike, it will be opened only with keys and the control unit that regulates its electrical impulses.
Traditionally, installing an electric strike involved cutting out a portion of the doorjamb to remotely remove a cylindrical lock's latchbolt from the pocket in the strike. This is not only undesirable, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.
Recently, several electric strike makers have come up with a brand new electric strike dubbed the "No Cut" strike that doesn't require cutouts in the doorjamb to function. These strikes use a special design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.
The strike is fitted with an internal ramp that lifts the latchbolt as well as the keeper when it receives an indication from the reader.
