How to Replace Door Locks
The first protection is your door lock. It can stop unauthorised access to your home. Locks might require replacement due to signs of wear and tear or other circumstances such as moving into a new house or a break-in.
To begin, determine the size of your cylinder by measuring the distance between the adjustment screw and the middle of the knob lock cylinder. This measurement will allow you to buy the right lock.
Deadbolt
Installing a deadbolt is excellent way to protect your door from burglars. The bolt extends into the strike plate that is on the doorframe when locked, making it much more difficult for a burglar to break in through the door. A single-cylinder deadbolt is activated by a key located on the exterior and a thumb-turn piece that is located inside. A deadbolt will only work if it is installed correctly.
First, you will need to determine if the door already has a hole to install deadbolts, or if it requires drilling. Mark the position of the hole for the deadbolt on the exterior of the door using the template included with your lock installation set. Then, use the tape measure to determine the height the deadbolt needs to be. Mark this height on the door edge and use a speedsquare to draw a straightline across the mark that you made for the bolt hole.
Then, use a power drill to drill this spot until the hole is on the other side of the door. This could take a while. Then, sand down the hole and the edge of the door so that it's smooth. At this moment, it's a good idea to paint or stain your door.
Remove any screws that are visible from the deadbolt. This will reveal both the front and rear assemblies of the deadbolt and its internal bolt. Then unscrew the old bolt and replace it by an alternative bolt that matches your door hardware. You will need to unscrew the bolt from a setplate. After that, you'll have to chisel the area on the door frame for the strike plate.
If your strike plate is not aligned, it's likely because the previous installer didn't properly mortise it or a weatherstripping popped up and changed the strike's position. To fix this problem you'll need to remortise both the strike plate and the deadbolt. Once you have completed this Test the deadbolt by closing and locking it. Make sure the bolt extends into the strike plate, and then test the key to make sure it is able to open and close smoothly.
Knob
It could make your home or business less secure when the door knob is damaged. It could make opening or closing the door more difficult, so it is recommended to replace the knob. It shouldn't take longer than 30 minutes. You can use a screwdriver or pliers to take off the knob or handle Be careful not to harm any other parts on the door.
Before you begin, you'll want to spray WD-40 or some other dry lubricant onto the mechanism of the knob on your door. This will let the new lock slide smoothly as you turn it. To ensure that it operates properly it is essential to select the knob and handle that match the doors you already have. If you don't have a doorknob that is compatible then you'll have to purchase a replacement.
To begin the replacement process, first look over the knob or handle to determine what screws hold it in place. If there aren't screws, you can use the screwdriver to insert the cover plate between the screws plate hidden behind it.
After removing the old knob take it apart and look for indications of damage and rust. You'll need to clean it off if there are any marks or dents, but you shouldn't have to do anything major if the knob is in good shape.
Install the new knob. First, examine the two new knobs to make sure that you're choosing the right one for your door. You should select one that has an extending rod designed to interlock with the rod mechanism of the second knob. After you've inserted the new knob in the hole then slide it into the latch.
Test the spring by pressing it repeatedly. The latch should then spring back up each time. Install the second knob and lock it to the rod mechanism of the first knob. Thread the long screws of the interior doorknob through 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 through the doorjamb to secure it shut. The latch is operated either by a handle or knob located inside the door, or by a thumb-turn on the exterior. A deadbolt can be used to secure a latch and keep burglars from piercing the glass of the door. It can also guard against the accidental or deliberate closing by pets or children. It is possible to install a latch with either a single-cylinder deadbolt or double-cylinder deadbolt based on the level of security.
Installing homepage involves the same steps as installing a deadbolt, but there are a few variations. To make sure that the new lock is compatible, first measure the setback on the doorjamb with the 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. The standard setback is 2 3/8 to 2. 3/4 inches. If your setback is larger than that, you might need to purchase an extra-long latch from a locksmith or hardware store.
Then, make a hole for a latch plate in the edge of the doorjamb. Use a chisel and make the mortise for the latch. Make sure the depth is sufficient for the faceplate to be in line with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned correctly.
If the strike is placed too high, the door could be pushed in or pressure applied to it with a crowbar or tire iron. This can also cause the doorjamb to break. To correct this, the strike could be lowered by drilling a new hole through the doorjamb, and then chiseling out the core of the hole that was previously drilled.
Installing the new strike plate is the final step. This can be done by screwing the new plate over the screw holes that are already in place. Then apply wood putty to cover the old screw holes and the bolt hole that won't be used. After the putty is dry, sand it to an even finish.
Strike
The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is a vital part of the lock's security because it prevents the door from opening, and also provides additional resistance to force or kick. If a door is equipped with an electric strike, it can be opened with a key or the control unit that controls the electrical impulses.
Traditionally the installation of an electric strike required cutting a section of the doorjamb to remotely release the latchbolt of a circular lock from the pocket in the strike. This is not only unattractive, but also exposes the mechanism of the latchbolt and keeper to unauthorized users.
Recently, a number of electric strike makers have come up with an innovative type of electric strike called the "No Cut" strike that doesn't require a cutout in the doorjamb 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 which lifts the latchbolt as well as the keeper when it receives the signal of the reader. The keeper and latchbolt are pushed on the ramp thanks to the retract. When the door is shut, the deadbolt remains retracted, and the latchbolt is retracted into the keeper.
Installing an electric strike is an easy task, especially if you are replacing an existing strike door. If you're planning to upgrade an access control system to an electric strike, you must ensure that the new system is compatible. It is also necessary to ensure that the strike is properly wired to your access control system and is set up for fail-safe operation.
Upgrade your strike plates with heavy duty strike plates to stop unauthorized entry. The plates are made of up to six screws of three inches instead of two screws of three-fourths inch. These screws are longer, making it more difficult for people to break the frame and then reach inside to turn the piece that turns the thumb of a single cylinder deadbolt.
