Then, put in the new knob and interlock it with the rod mechanism on the first knob.

Latch
A latch is a piece metal that extends through the doorjamb to hold it shut. It is operated by a knob or handle on the inside of the door or a thumb turn on the outside side of the door. Deadbolts can be used to secure a latch and stop burglars from piercing the glass of the door. It also helps protect against accidental or intentional closing by animals or children. You can 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 exactly the same as installing a latch but there are some differences. First, you must measure the setback of the doorjamb using a tape measure to make sure that the new lock will fit. The setback is the distance from the edge of the doorjamb to the center of the hole for the faceplate for the latch. A typical setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you may have to purchase a larger latch from a hardware store or locksmith.

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 important part of the security of a lock, as it keeps the door shut and offers additional resistance to force or kicking applied to the door. If a door comes with an electronic strike, it can be opened only with a key and the control unit that controls its electrical impulses.
In the past, installing an electronic strike required cutting off a part of a doorjamb to let the latchbolt of a cylindrical lock from the pocket that is inside the strike. This modification can be an issue in terms of the appearance of openings, and it also exposes the keeper mechanism and latchbolt to unauthorized users.
Recently, a number of electric strike manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout to operate. They use a specific design that allows the latchbolt and keeper to slide into the pocket without causing damage to the faceplate of the doorjamb.
The strike is fitted with an internal ramp that raises the latchbolt and keeper when it receives an indication from a reader. The latchbolt and keeper are pushed higher up the ramp due to retract. When the door is shut, the deadbolt remains retracted, and the latchbolt retracts in the keeper.
Installing an electric strike is an easy task, especially in the case of replacing an existing strike door. If you are upgrading an access control system to an electric strike, you need to ensure that your new system is compatible. Also, you must make sure that the strike is properly connected to your access control system and set up to operate in a fail-safe manner.
One method to guard against access by unauthorized persons is to upgrade the strike on your doors to a high-quality strike plate. These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws that are typically used in regular strikes. The longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt cylinder more difficult.
