To begin the replacement process, first examine the old knob or handle to see what screws are holding it in place. If there aren't any screws, you can make use of a screwdriver and wedge it between the cover plate and the plate with hidden screws and remove it.
Once you've removed the knob that was previously used, look it over for any signs of damage or rust. If the knob is damaged or has marks or scratches, you'll have clean it. Otherwise, it shouldn't require any major work.
Install the new knob. You must first study the two knobs to make sure that you've selected the right one for the door.

Latch
A latch is a steel piece that extends into the doorjamb to secure it closed. The latch is operated either via a knob or handle on the inside of the door, or by a thumb-turn on the outside. The latch can be secured using deadbolts to prevent intruders from breaking in through the glass of the door. It also protects against accidental or intentional closing of the door by children or pets. You can install an entry point with either a single-cylinder deadbolt or double-cylinder deadbolt, depending on the level of security.
Installing a deadbolt can be the same as installing a latch but there are some differences. To make sure that the new lock will fit, first take a measurement of the setback on the doorjamb using an instrument such as a tape measure. 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 you have a higher setback, you might need to purchase a longer latch from a hardware store or locksmith.

Installing the new strike plate is the final step. This can be accomplished by screwing the new plate over the existing screwholes. Use wood putty afterwards to fill in any existing holes for screws or bolts that aren't being used. After the putty is dry then sand it to an even finish.
Strike
The piece of metal that is inserted between the deadbolt and latch when the door is closed is an electric strike. It is an essential part of the lock's overall safety because it stops the door from opening and gives an additional level of resistance to force or kicking. If a door has been equipped with an electric strike, it can be opened using a key or the control unit which controls the electrical impulses.
In the past, putting in an electronic strike required cutting a portion of a doorjamb, which would remove the latchbolt on a cylindrical lock from the pocket within the strike. This modification can be an inconvenience in regards to the aesthetics of an opening as well as exposing the keeper mechanism and latchbolt to unauthorized users.
Recently, a number of electric strike manufacturers have created a "No Cut" type of strike that doesn't require a cutout for operation. They use a specific design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.
The strike is equipped with an internal ramp that lifts the latchbolt as well as the keeper when it receives the signal of a reader. The keeper and latchbolt are pushed higher on the ramp thanks to the retraction. When the door is shut, the deadbolt stays extended and the latchbolt is retracted into the keeper.
Installing an electric strike can be a simple process, especially if you are replacing an existing strike door. If you're planning to upgrade an existing access control system to an electric strike, you need to ensure that your new system is compatible. You will also need to make sure that the strike is properly connected to your access control system and that it is designed to operate in a fail-safe manner.
One way to protect against intrusions by thieves is to upgrade the strike on your doors to a robust strike plate. These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws commonly used in regular strikes. These longer screws make it difficult for someone to break the frame and reach inside to turn the thumb turn piece of a single cylinder deadbolt.
