Deadbolt

If you want to make sure your door is safe from burglars, it's a good idea to install a deadbolt. The bolt extends into the strike plate that is on the doorframe when it is locked, making it much more difficult for a burglar to gain entry into the door. A single-cylinder deadbolt is activated with a key on the exterior, and the thumb-turn mechanism that is located inside. A deadbolt is only effective if it's installed correctly however.

You will first need to determine whether the door already has an existing hole for a deadbolt, or if you need to drill it. With the template included with the lock installation kit mark the location of the hole for the deadbolt on the door's surface. Use a tape measure to determine the height of the deadbolt. Then, mark the high point on the outside of the door. Use a speed square to draw a straight line across the mark you made for the bolt hole.

Next, use a power drill to bore this spot until the hole reaches the other side of the door. This may take some time. Sand the hole and the door edge to smooth it. It's also recommended to stain or paint the door at this point.

Remove any visible screws from the deadbolt. This will reveal the front and back assemblies of the deadbolt, and also the bolt inside. Then, loosen the bolt and replace it with a brand new one that matches the door hardware. You'll need to remove the bolt from a setplate. After that, you will need to chisel out the area for the strike plate on the door frame.

If your strike plate is out of alignment It could be due to the previous installer didn't mortise it properly or that a weatherstripping has changed the strike's location. You will need to re-mortise the strikeplate and possibly even the deadbolt to correct this problem. Close and lock the deadbolt once you have completed this step. Be sure the bolt extends into the strike plate then test the key to ensure it is able to open and close smoothly.

To ensure proper operation, it's important to choose a knob and handle that match the doors you already have. If you don't have a matching doorknob and handle, you'll need to purchase a replacement upvc door locking mechanism.

Before you begin replacing the knob, look over the knob you replaced to determine which screws are holding it in place. If there aren't screws, you can use the screwdriver to insert the cover plate into the screws plate that is hidden.

After you have removed the knob examine it for indications of damage and rust. You'll have to scrub it off if there are any marks or dents however you don't need to do anything if the knob is in good shape.

Install the new knob. You must first study the two knobs in order to make sure that you've chosen the right one for the door. You'll need to select one with an extending rod that will interlock with the rod mechanism of the second knob. Once you've put the new knob in the hole in the door, carefully place it in the latch.

Test the spring by pressing down on it repeatedly. The latch should spring back up every time. Install the second knob, and lock it to the rod mechanism of the first knob. Thread the long screws from the doorknob's interior through the cylinder holes on the exterior knob, and fix it in the knob's position.

Latch

A latch is a metal piece that extends into the door jamb to keep it shut. It is operated by a handle or knob on the interior side of the door or by a thumb turn on the outside side of the door. The latch can be secured with deadbolts to prevent intruders from breaking in through the door's glass. It also offers protection from the accidental or deliberate closing of the door by pets or children. A latch can be set using one cylinder deadbolt or double cylinder deadbolts, depending on the security level you prefer.

Installing a deadbolt is the same as installing a latch, but there are some differences. First, measure the setback of the doorjamb with a tape measure to make sure that the new lock will fit. The setback is measured from the edge of the 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 larger it is possible to purchase a latch that is longer from a hardware or locksmith store.

The next step is to drill an edge bore hole in the doorjamb to accommodate the latch plate. 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 strike plate in the correct position to ensure it's in the right position.

If the strike is too high, you could kick the door in or apply pressure with the tire iron or crowbar. This could also cause cracks in the doorjamb. This can be fixed by drilling a new hole into the doorjamb and then cutting the core from the hole that was previously made.

The final step is to install the new strike plate, which is done by screwing it in place over the screw holes that are already in place. Then you can use wood putty to fill in the old screw holes and the bolt hole that will not be used. After the putty has dried then sand it to an even finish.

Strike

The piece of metal that connects the deadbolt and latch when the door is closed is an electric strike. It is an essential component of the lock's overall security, as it prevents the door from opening, and also provides additional resistance to force or kicking. If a upvc door locking mechanism replacement is fitted with an electronic strike, it will be opened by using an entry key and a control unit that regulates its electrical impulses.

In the past, installing an electronic strike was as simple as cutting off a part of a doorjamb, which would remove the latchbolt on a cylindrical lock from the pocket within the strike. This modification can be an issue in terms of the appearance of openings as well as exposing the latchbolt and keeper mechanism to any unauthorised users.

Recently, several electric strike manufacturers have created a new type of electric strike, dubbed the "No Cut" strike that doesn't need an opening in the doorjamb for operation. These strikes utilize a special design to allow the keeper and latchbolt to slide into the strike pocket without damaging the faceplate of the doorjamb.

The strike is equipped with an internal ramp that raises the latchbolt and keeper whenever it receives the signal of a reader. The retracting of the keeper as well as latchbolt pushes them up higher on the ramp, locking the door. When the door is closed the deadbolt remains in place and the latchbolt is retracted into the keeper.

Installing an electric strike can be an easy process, particularly in the case of replacing an existing strike door. If, however, you are upgrading to an electric strike in an access control system, you'll be required to ensure that the new system is compatible with the model of lock you have installed. It is also necessary to make sure that the strike is properly connected to your access-control system and is configured to operate in a fail-safe way.

Upgrade your strike plates to heavy duty strike plates to block unauthorized entry. The plates utilize four to six three-inch screws instead of the two three-fourth inch screws that are typically used in standard strikes. The longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt for a cylinder more difficult.
