First, you must find out if the door has a hole that is suitable for a deadbolt, or if you have to drill it out. With the template included with the lock installation kit mark the location of the deadbolt hole on the door's surface. Then, use your tape measure to determine the height the deadbolt needs to be. Then, mark this high point on the outside of the door. You can then use a speed square to draw an even line across the mark you made for the bolt hole.

Install the new knob. It is important to first look over the two knobs in order to make sure that you are choosing the right one for the door. You'll want to pick one with an extending rod designed to interlock with the rod mechanism on the second knob. Once you've put the new knob over the hole in the composite door replacement lock carefully slide it into the latch.

Install the second knob, and lock it to the rod mechanism of the first knob. Thread the long screws of the interior doorknob into the holes for cylinders on the exterior knob and fix it in the knob's position.

Latch

A latch is a piece metal that extends into the doorjamb to secure it closed. The latch is operated either by a handle or knob located inside the door, or by a thumb-turn on the exterior. A latch can be secured with deadbolts to prevent intrusions from piercing the door's glass. It can also guard against intentional or accidental closing by animals or children. A latch can be installed with one cylinder deadbolt or double cylinder deadbolts based on the level of security you prefer.

Installing a deadbolt can be the same as installing a latch, however there are some differences. First, measure the setback of the doorjamb using a tape measure to make sure that the new lock will fit. The setback is measured from the edge of doorjamb all the way 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 greater than that, you might need to purchase an extra-long latch from a locksmith or hardware store.

The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Utilize a chisel to smooth out the mortise for the latch making sure it's large enough to allow the faceplate of the new latch to sit flush with the doorjamb. Tape the strike plate in place to make sure it is positioned correctly.

Strike

The piece of metal that is inserted between the latch and deadbolt when the door is shut is an electric strike. It is an essential component of the lock's overall safety, as it prevents the door from opening, and also provides additional resistance to force or kick. If a door comes with an electronic strike, it can be opened only with keys and the control unit that regulates the electrical impulses.

Traditionally the installation of an electric strike involved cutting a section of the doorjamb to release the latchbolt of a cylindrical lock from the pocket of the strike. This is not only undesirable, but also exposes the mechanism for the latchbolt and the keeper to intruders.

Recently, a number of electric strike manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout in order to operate. These strikes utilize a special design that allows the latchbolt and keeper to slide into the strike pocket without damaging the faceplate of the doorjamb.

The strike has an internal ramp that raises the latchbolt and keeper when it receives an electrical signal from a controller or reader. The keeper and latchbolt are pushed up the ramp due to retract. When the door is closed 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 a upvc door lock a strike on an existing door. If you're planning to upgrade an existing access control system to an electric strike, you need to ensure that the new system is compatible. It is also necessary to ensure that the strike is properly connected to your access control system and that it is set up for fail-safe operation.

One method to guard against unauthorized access is to upgrade the strike on your doors to a high-quality strike plate. These plates use four to six three-inch screws instead of the two, three-fourth inch screws that are typically used in regular strikes. The longer screws make it harder for people to break the frame and reach inside to turn the thumb turn piece of a single cylinder deadbolt.
