Deadbolt

If you're looking to ensure that your door is secure from criminals, it's a great idea to install deadbolts. When the bolt is extended into the strike plate of the doorframe it makes it more difficult for an intruder to break through the door. A single-cylinder deadbolt is activated by a key located on the exterior and the thumb-turn mechanism situated inside. A deadbolt will only work if it's installed correctly, though.

First, you must find out if the door has an existing hole for a deadbolt or if you need to bore it out. Utilizing 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. Mark this measurement on the door's edge and use the speedsquare to draw a straightline across the mark you made for the bolt hole.

Then, use a power drill to bore this hole until it reaches the other side of the door. This could take a bit of time. Sand the hole and the edge of the door to smooth it. At this point, it's a good idea also to paint or stain your door.

Once the door is ready take off any screws that are visible on the existing deadbolt. This will reveal the front and back assembly of the deadbolt, and also the internal bolt. Then, unscrew the bolt and replace it with a new one that matches the door hardware. It is necessary to remove the bolt from a setplate. After this is done it is time to chisel out the area for the strike plate on the door frame.

If your strike plate is out of alignment, it could be because the previous installer failed to mortise it properly or that a weatherstripping has changed the strike's position. To fix this issue it is necessary to remortise the strike plate as well as the deadbolt. Close and lock the deadbolt once you've completed this step. Test the deadbolt by closing and locking it after the bolt has been extended into the strike plate.

Knob

It could make your home or business less secure when the door knob is worn. It can make it more difficult to open or close the door, so it's a good idea to replace patio door lock the knob. It shouldn't take you more than 30 minutes. Use pliers or a screwdriver to take off any knobs or handles. Be cautious not to harm the other components of the door.

Before you begin you'll need to spray WD-40 or some other dry lubricant on the mechanism of the knob on your door. This will allow the new lock slide smoothly when you turn it. To ensure proper operation it is important to select the knob and handle that match your existing doors. If you don't already have a doorknob that matches then you'll have to purchase a new one.

To begin the replacement lock for composite door process, first look at the knob or handle to see what screws are holding it in place. If there aren't any screws you can use a screwdriver to insert between the cover plate and the plate with hidden screws and remove it.

After you have removed the knob examine it for signs of rust and damage. You'll need to clean it off if there are any scratches or marks however you don't need to do anything when the knob is in good working order.

Now is the time to put in the new knob. You should first examine the two knobs to make sure that you've chosen the correct one for your door. You'll need to choose one with an extended rod that is interlocked with the rod mechanism of the second knob. Once you've put the new knob into the hole then slide it into the latch.

Thread the latch plate screws down and then test the spring by pushing down several times. The latch should rise every time. Next, install the other new knob and lock it with the rod mechanism on the first knob. Thread the long screws from the interior doorknob through the holes for cylinders on the outside knob and secure it in the knob's position.

Latch

A latch is a metallic piece that extends out into the doorjamb to secure it closed. It is operated by a knob or handle on the interior side of the door or by a thumb turn on the outside side of the door. A latch can be secured by a deadbolt to keep intrusions from piercing the door's glass. It also provides protection from the accidental or deliberate closing of the door by children or pets. A latch can be set using a single cylinder deadbolt or double cylinder deadbolts, based on the level of security you prefer.

Installing a latch requires the same steps as installing a deadbolt, however there are some variations. To ensure that the new lock is compatible first, you must take a measurement of the setback on the doorjamb using an instrument such as a tape measure. The setback is the distance between the edge of the doorjamb, to the center of the hole to accommodate the faceplate for the latch. A standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you might need to purchase a larger latch from a hardware shop or locksmith.

Then, make a hole for the latch plate in the edge of the doorjamb. Use a chisel and chisel the latch mortise. Make sure the hole's depth is enough for the faceplate to be in line with the doorjamb. Put the strike plate into place to make sure it is positioned correctly.

If the strike is positioned too high, the door can be kicked in or pressure applied to it with a crowbar or tire iron. This can also cause the doorjamb's to crack. To fix this, the strike could be reduced by drilling a second hole through the doorjamb, and then chiseling out the core of the previous hole.

Installing the new strike plate is the last step. This can be accomplished by screwing the new plate into the existing screw holes. Use wood putty then to fill in any existing screw holes or bolt holes which aren't going to be used. Once the putty has dried, sand it to an even finish.

Strike

The piece of metal that is inserted between the latch and deadbolt when the door is shut is an electric strike. It is a crucial component of the overall security of a lock 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 will only be opened using an entry key or the control unit which controls its electrical impulses.

Traditionally the installation of an electric strike required cutting out a portion of the doorjamb to remotely remove the latchbolt of a circular lock from the pocket in the strike. This is an issue when it comes to the aesthetics of an opening, and it also exposes the latchbolt and keeper mechanism to unintentional users.

Recently, several electric strikes manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without causing damage to the faceplate of the doorjamb.

The strike is equipped with an internal ramp that raises the latchbolt and keeper whenever it receives an indication from an individual reader. The retracting of the keeper as well as latchbolt causes them to rise on the ramp, locking the door. When the door is closed, the deadbolt remains retracted, and the latchbolt retracts in the keeper.

Installing an electric strike is an easy process, particularly in the case of replacing a strike on an existing door. If you're upgrading an access control system to an electric strike, you need to ensure that the new system is compatible. You will also need to ensure that the strike is connected to your access control system and is set up for fail-safe operation.

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 use four to six three-inch screws instead of the two three-fourth inch screws commonly used in standard strikes. These screws are longer and make breaking the frame to reach the piece that turns the thumb on a single deadbolt cylinder more difficult.
