Latch
A latch is a piece metal that extends through the door jamb to keep it closed. It is operated by a handle or knob on the inside of the door or by a thumb turn on the outside side of the door. A deadbolt can be used to secure a latch and stop intruders from breaking through the glass of the door. It also offers protection from accidental or intentional closing of the door by pets or children. A latch can be installed with single cylinder deadbolts or a double cylinder deadbolt, according to the security level you prefer.
Installing a latch involves the same steps like installing a deadbolt however, there are a few variations. First, measure the setback of the doorjamb by using 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 for the latch faceplate. The standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you might need to purchase a longer latch from a hardware store or locksmith.
Next, make a hole for a latch plate in the edge of the doorjamb. Use a chisel to chisel out the mortise for the latch, making sure it's deep enough for the faceplate of the new latch to sit close to the doorjamb. Place the strikeplate on the floor to ensure it's placed correctly.

Installing the new strike plate is the last step. This can be done by fixing the new plate to the existing screw holes. Utilize wood putty to fill in any existing holes for screws or bolts that won't be used. After the putty has dried you can sand it until it has an even finish.
Strike

It is an important part of a lock's overall security, as it keeps the door shut and also provides additional resistance to kicking or force applied to the door. If a door has been equipped with an electric strike, it can be opened with keys or the control unit that controls the electrical impulses.
Traditionally the installation of an electric strike required cutting a small portion of the doorjamb to remotely remove the latchbolt of a cylindrical lock from the pocket within the strike. This modification is not just ugly, but also exposes the mechanism for the latchbolt and keeper to unauthorized users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout for operation. The strikes have a unique 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 the signal of the reader. The latchbolt and keeper are pushed up the ramp by the retract. When the door is closed the deadbolt remains in retracted and the latchbolt retracts into the keeper.

It is also necessary to make sure that the strike is connected to your access-control system and set up to operate in a fail-safe manner.
Upgrade your strike plates to high duty strike plates to stop unauthorised entry. The plates are made of up to six screws of three inches instead of the usual two screws of three-fourths inches. These screws are longer, making it more difficult for anyone to break the frame and then reach inside to turn the thumb turn piece of a single cylinder deadbolt.
