Latch
A latch is a piece of metal that extends into the doorjamb to hold it shut. It is operated by a knob or handle on the interior side of the door or a thumb turn on the outside side of the door. A deadbolt can be used to secure a latch and stop intrusions from breaking through the glass of the door. It can also protect against intentional or accidental closing by pets or children. It is possible to install an entry point with either a single-cylinder deadbolt, or a double-cylinder deadbolt depending on the level of security.
Installing a deadbolt is the same as installing a latch however, there are some distinctions. First, determine the setback of the doorjamb using a tape measure to make sure the new lock will fit. The setback is measured from the edge of the doorjamb all the way to the center of hole for the latch plate. Standard setbacks are 2 3/8 to 2. 3/4 inches. If your setback is larger it is possible to purchase a latch that is longer from a hardware or locksmith store.
The next step is to drill an edge bore hole in the doorjamb to accommodate the latch plate. Use a chisel to chisel out the mortise for the latch, making sure it's deep enough to allow the faceplate of the new latch to sit in a flush position with the doorjamb. Tape the strikeplate in place to ensure it is positioned correctly.
If the strike is set too high, the door may be pushed in or pressure put on it with a crowbar or tire iron. This could cause the doorjamb to crack. To remedy this, the strike can be lowered by drilling another hole into the doorjamb and chiseling out the core of the previous hole.
The final step is to mount the new strike plate, which can be done by screwing it in place over the existing screw holes. Then apply wood putty to fill in the old screw holes and the bolt hole that will not be used. After the putty has dried, sand it smooth for professional results.
Strike
The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is an essential part of the lock's overall security because it prevents the door from opening and gives an additional barrier to force or kick. If a door comes with an electronic strike, it can be opened by using a key and the control unit that regulates the electrical impulses.
Traditionally, installing an electric strike required cutting a small portion of the doorjamb in order to remotely remove the latchbolt of a circular lock from the pocket of the strike. This is not only unattractive however, it also exposes the mechanism for the latchbolt and keeper to unauthorized users.
Recently, a number of electric strike manufacturers have created a "No Cut" type of strike that does not require a cutout to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate.
The strike has an internal ramp that raises the latchbolt and keeper when it receives an electrical signal from a reader or controller. The retracting of the keeper and latchbolt pushes them up higher on the ramp, which locks the door. When the door is shut, the deadbolt remains in place and the latchbolt retracts into the keeper.
Installing an electronic strike is a simple procedure, particularly in the case of replacing an existing strike. If you are upgrading an access control system to an electric strike, it is important to make sure that the new system is compatible. It is also necessary to ensure that the strike is properly connected to your access-control system and set up to function in a fail-safe way.

These plates use up to six screws of three inches instead of the standard two screws of three-fourths of an inch. These screws are longer, making it difficult for anyone to break the frame and reach inside to turn the thumb turn piece of a single cylinder deadbolt.
