Deadbolt
If you're looking to ensure that your door is secure from criminals, it's a great idea to install deadbolts. 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, and a thumb-turn device situated inside. A deadbolt will only work only if it's correctly installed however.
First, you'll need to determine if the door already has a hole to install a deadbolt or if it has to be bored. Utilizing the template included with the lock installation kit, mark the location of the hole for the deadbolt on the door's surface. Then, you can use your tape measure to determine how high the deadbolt should be. Then, mark this height on the side of the door. You can then use a speed square to draw an even line across the mark you made for the bolt hole.
Then by using an electric drill, bore out the hole until it is on the opposite side of the door. This could take a while. Then, sand the hole and the edges of the door until it is smooth. At this moment, it's a good idea to stain or paint your door.
Remove any screws that are visible from the deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt inside. Remove the bolt and replace it with the new bolt to match your door hardware. You will need to unscrew the bolt from the setplate. After this is done then you need to cut out the space for the strike plate that is on the door frame.
If your strike plate is out of alignment it could be because the previous installer didn't mortise it properly, or a weatherstripping changed the strike's position. You'll need to re-mortise the strikeplate and possibly even the deadbolt itself to fix this issue. After this is done Test the deadbolt by closing it and locking it. Be sure the bolt extends into the strike plate then test the key to ensure it is able to open and close effortlessly.
Knob
If a door knob is damaged, it can make your business or home less secure. It may make it more difficult to open or close the door, so it's recommended to replace it. Replacing knobs is an easy DIY project and shouldn't take more than 30 minutes to complete. You can use a screwdriver or pliers to take off the knob or handle Be careful not to scratch any of the other components on the door.
Before you start, you'll want to spray WD-40 or some other dry lubricant on the mechanism of the door knob. This will help the new lock slide effortlessly as you turn it. It is essential to choose a quality knob and handle that matches your current doors to ensure that the lock is operating properly. If there's no match then you'll have to purchase a replacement doorknob and latch plate.
Before you begin the replacement process, examine the old knob to see what screws are that are holding it in place. If there aren't screws to hold it in place, you can use a screwdriver to secure the cover plate in between the screws plate that is hidden.
After you've removed the old knob, examine it for signs of rust or damage. It's important to clean it off if you notice any scratches or marks, but you shouldn't have to do anything when the knob is in good shape.
Now is the time to put in the new knob. Before you do that, look over the two new knobs to ensure that you're picking out the right one for your door. You'll want to pick one with an extending rod that's designed to lock into the rod mechanism of the second knob. Once you've put the new knob in the hole then slide it into the latch.
Thread the latch plate screws downwards and then test the spring by pushing down several times. The latch should then spring back up each time. Then, you can install the new knob and lock it to the rod mechanism on the first knob. Thread the long screws from the doorknob's interior through the holes for the cylinder on the outside knob and fix it in place.
Latch
A latch is a steel piece that extends into the door jamb to keep it shut. The latch is operated via a knob or handle on the interior of the door, or a thumb-turn on the outside. A latch can be secured by a deadbolt to keep intrusions from piercing the glass. It can also guard against the accidental or deliberate closing by animals or children. You can choose to install a latch with either a single-cylinder deadbolt or double-cylinder deadbolt depending on your preferred level of security.
Installing a deadbolt can be the same as installing a latch but there are some differences. To make sure that the new lock will work first, measure the setback on the doorjamb with a tape measure. The setback is the distance from the edge of the doorjamb to the middle of the hole for the latch faceplate. The standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you may have to purchase a more substantial latch from a hardware shop or locksmith.
The next step is to drill an edge bore hole into the doorjamb to accommodate the latch plate. Utilize a chisel to make the mortise for the latch. Make sure the depth is enough for the faceplate to be flush with the doorjamb. Tape the strike plate in place to make sure it is positioned correctly.
If the strike is set too high, the door can be pushed in or pressure put on it using a crowbar or tire iron. This can also crack the doorjamb. To fix this, the strike could be lowered by drilling a new hole into the doorjamb and chiseling out the core of the old hole.
Installing the new strike plate is the last step. This can be done by screwing the new plate over the existing screw holes. Then you can use wood putty to fill in the screw holes that were previously used and the bolt hole that will not be used. After the putty is dry you can sand it until it has an even finish.
Strike
An electric strike is the metallic piece where the latch and deadbolt engage when the door is shut. It is a vital component of the overall security of a lock since it keeps the door shut and provides extra resistance to kicking or force applied to the door. If a door comes with an electronic strike, it can be opened only with keys and the control unit that controls its electrical impulses.
In the past, putting in an electronic strike required cutting a piece of a doorjamb, which would let the latchbolt of a cylindrical lock from the pocket inside the strike. This modification 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 created a brand new electric strike called the "No Cut" strike that doesn't need an opening in the doorjamb to function. 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 has an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a controller or reader. The keeper and latchbolt are lifted higher on the ramp thanks to the retract. When the door is closed the deadbolt remains at a lower position and the latchbolt retracts into the keeper.
Installing an electric strike is an easy task, especially if you are replacing a strike on an existing door. However, if repairmywindowsanddoors to an electric strike to use with an access control system, you will have to ensure that your new system is compatible with the type of lock you've installed. You will also need to make sure that the strike is wired to your access control system and that it is designed to operate in a fail-safe manner.
One way to safeguard against intrusions by thieves is to upgrade the strike on your doors to a robust strike plate. These plates use up to six screws of three inches instead of two screws of three-fourths inches. These longer screws make breaking the frame to reach the piece that turns the thumb on a single deadbolt for a cylinder more difficult.
