Deadbolt
Installing a deadbolt can be a ideal way to secure your door from burglars. The bolt extends into the strike plate on the doorframe when locked, making it much more difficult for a burglar to break in through the door. A single cylinder deadbolt can be activated using a key on the exterior side and a thumb turn part on the inside. A deadbolt is only effective when it's properly installed, though.
First, you'll need to find out if the door has a hole for a deadbolt or if it requires drilling. Mark the position of the hole for the deadbolt on the exterior of the door using the template that came with your lock installation kit. Use a tape measure to determine the height of the deadbolt. Mark this height on the door edge, and then use a speedsquare to draw a straight line across the mark that you made for the bolt hole.
Then, use a power drill to drill this area until the hole extends to the other side of the door. This may take a while. Then, sand the hole and the edge of the door until it is smooth. It's also recommended to stain or paint the door at this point.
Remove any visible screws from the deadbolt. This will reveal both the front and rear assemblies of the deadbolt as well as its internal bolt. Then, remove the bolt and replace it by a new one to match the door hardware. The bolt is often attached to a set plate which you'll have to remove. After this, you'll need to chisel the door frame to accommodate the strike plate.
If your strike plate is out of alignment it could be because the previous installer did not mortise it properly or that an installation of a weatherstripping altered the strike position. You'll need to re-mortise the strikeplate and possibly even the deadbolt to correct this problem. Once this is completed Test the deadbolt by closing it and locking it. Make sure the bolt extends into the strike plate and then test the key to make sure it opens and closes smoothly.

Before you begin the replacement, look over the knob you replaced to determine which screws are that are holding it in place. If there are no screws to hold it in place, you can use a screwdriver to insert the cover plate in between the screws plate that is hidden.
Once you've removed the old knob, examine it for any signs of damage or rust. If the knob has any marks or scratches it's time to clean it. Otherwise it shouldn't need any major work.
It's time to install the new one. You must first study the two knobs to make sure that you've selected the right one for the door. upvc door locks replacement should select one that has an extending rod that's designed to lock into the rod mechanism of the second knob. After you've placed the new knob in the hole then slide it into the latch.
Thread the latch plate screws down and then test the spring by pressing down on it several times. The latch should rise each time. Next, install the other new knob and interlock it to the rod mechanism on the previous knob. Thread the long screws of the interior doorknob into the cylinder holes on the exterior knob and secure it in its place.
Latch
A latch is a piece of metal that extends into the doorjamb to hold it closed. The latch is operated by a knob or handle on the inside of the door, or a thumb-turn on the exterior. A latch can be secured using a deadbolt to keep intruders from breaking in through the glass. It also offers protection from the accidental or deliberate closing of the door by pets or children. You can install the latch using either a single-cylinder or double-cylinder deadbolt depending on the level of security.
Installing a latch follows the same steps as installing a deadbolt, however there are some variations. First, you must measure the setback of the doorjamb using a tape measure to be sure that the new lock will fit. The setback is the distance between the edge of the doorjamb to the middle of the hole to accommodate the faceplate for the latch. A typical setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you may have to purchase a more substantial latch from a hardware shop or locksmith.
Next, make a hole for the latch plate into the doorjamb's edge. Use a chisel to chisel out the mortise for the latch and ensure it's deep enough to allow the faceplate of the new latch to be flush with the doorjamb. Place the strike plate in place to ensure that 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 can also cause the doorjamb to break. To fix this issue, the strike can be reduced by drilling a second hole in the doorjamb and chiseling out the center of the previous hole.
Installing the new strike plate is the final step. This can be done by screwing the new plate over the existing screwholes. Then apply wood putty to cover the screw holes that were previously used and the bolt hole that will not be used. After the putty is dry, sand it to an even finish.
Strike
The piece of metal that connects the latch and deadbolt when the door is shut is an electric strike. It is a crucial component of a lock's overall security, as it seals the door and also provides additional resistance to kicking or force applied to the door. If a door is equipped with an electric strike, it can only be opened using keys or the control unit that governs its electrical impulses.
Traditionally the installation of an electric strike involved cutting out a portion of the doorjamb in order to release the latchbolt of a circular lock from the pocket of the strike. This is an inconvenience when it comes to the appearance of openings, and it also exposes the keeper mechanism and latchbolt to unintentional users.
Recently, a variety of electric strike manufacturers have developed a "No Cut" kind of strike that does not require a cutout for operation. These strikes use a special 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 and keeper whenever it receives an electrical impulse from a reader or controller. The keeper and latchbolt are lifted higher on the ramp thanks to the retraction. When the door is closed the deadbolt remains retracted, and the latchbolt retracts into the keeper.
Installing an electric strike is a simple process, especially in the case of replacing an existing strike door. If you're upgrading an existing access control system to an electric strike, you need to make sure that the new system is compatible. It is also necessary to ensure that the strike is properly connected to your access-control system and is configured to operate in a fail-safe manner.
One method to guard against intrusions by thieves is to upgrade the strike on your doors to a heavy-duty strike plate. These plates use up to six screws of three inches instead of the usual two screws of three-fourths inches. These screws are longer, making it harder for anyone to break the frame and then reach inside to turn the thumb turn piece of a single deadbolt cylinder.
