Then, you can install the new knob and lock it to the rod mechanism on the previous knob. Thread the long screws of the doorknob's interior through the holes for the cylinder on the exterior knob, and lock it into the knob's position.

Latch

A latch is a metal piece that extends into the doorjamb to keep it closed. The latch can be operated by a handle or knob on the interior of the door, or by a thumb-turn on the exterior. The latch can be secured using deadbolts to prevent intruders from breaking in through the glass. It can also guard against intentional or accidental closing by children or animals. You can install the latch using either a single-cylinder or double-cylinder deadbolt based on your preferred level of security.

Installing a latch requires the same steps like installing a deadbolt however there are some differences. First, determine the setback of the doorjamb with an instrument to make sure that the new lock will fit. The setback is measured from the edge of doorjamb up to the center of hole for the latch plate. The standard setback is 2 3/8 to 2 3/4 inches. If your setback is higher it is possible to purchase an extra-long latch from a hardware or locksmith store.

The next step is to drill an edge bore hole in the doorjamb for the latch plate. Utilize a chisel to cut the mortise of the latch. Make sure the hole's depth is enough to allow the faceplate to be flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned correctly.

If the strike is too high, you can knock the upvc door replacement lock down or apply pressure with a tire iron or crowbar. This could cause the doorjamb's to crack. This can be repaired by drilling a new hole through the doorjamb and then cutting the core from the hole that was previously made.

Strike

The metal piece that engages the deadbolt and latch when the patio door lock replacement is shut is an electric strike. It is an essential component of the lock's security because it prevents the door from opening and provides an additional barrier to force or kicking. If a door is fitted with an electronic strike, it can be opened only with a key and the control unit that regulates the electrical impulses.

Traditionally the installation of an electric strike meant cutting a section of the doorjamb to release the latchbolt of a cylindrical lock from the pocket in the strike. This is not only unattractive however, it also exposes the latchbolt mechanism and keeper to unauthorized users.

Recently, a number of electric strike manufacturers have created a brand new electric strike dubbed the "No Cut" strike that doesn't need an opening in the doorjamb to function. 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 has an internal ramp that lifts the keeper and latchbolt when it receives an electrical signal from a reader or controller. The latchbolt and keeper are pushed higher up the ramp due to retract. When the door is closed, the deadbolt stays extended and the latchbolt is retracted into the keeper.

Installing an electric strike is a simple process, especially if you are replacing a strike on an existing door. If you are upgrading an access control system to an electric strike, you must ensure that the new system is compatible. Also, you must make sure that the strike is connected to your access control system and is set up to operate in a fail-safe manner.

One way to protect against access by unauthorized persons 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 that are typically employed in regular strikes. The longer screws make it more difficult for people to break the frame and then reach inside to turn the thumb turn piece of a single deadbolt cylinder.
