Deadbolt
Installing a deadbolt is a great way to secure your door against intruders. When the bolt is extended into the strike plate of the doorframe it makes it harder for an intruder to get through the door. A single cylinder deadbolt is activated using a key on the exterior side and a thumb turn piece on the inside. Deadbolts can only function only if it is correctly installed.
First, you must determine whether the door already has a hole that is suitable for a deadbolt or if you need to bore it out. Using the template that comes with the lock installation kit mark the location of the deadbolt hole on the door's surface. Use a tape measure to determine the height of the deadbolt. Mark this high point on the door's edge. Use a speedsquare to draw a straightline across the mark you made for the bolthole.
Then using the power drill, drill through the hole until it is on the opposite side of the door. This could take a bit of time. Sand the hole and edge of the door to smooth it. It's also an excellent idea to paint or stain the door at this point.
Remove any visible screws from the deadbolt. This will reveal the front and back assemblies of the deadbolt as well as the internal bolt. Then, remove the bolt and replace it with a new one to match the door hardware. It is necessary to remove the bolt from the setplate. After that, you'll have to chisel the surface of the door frame for the strike plate.
If your strike plate is misaligned It's likely that the previous installer didn't mortise it correctly or a weatherstripping came along and changed the strike position. To fix this issue it is necessary to remortise both the strike plate and the deadbolt. Once you have completed this check the deadbolt by closing and locking it. Make sure the bolt extends into the strike plate, and then test the key to ensure it closes and opens effortlessly.
Knob

Spray WD-40, or another dry lubricant on the mechanism of your door knob before you begin. This will let the new lock slide smoothly when you turn it. To ensure that it operates properly it is important to select a knob and handle that match the doors you already have. If you don't have a doorknob that is compatible and handle, you'll need to purchase a replacement.
To begin the replacement process, examine the old knob or handle to see what screws hold it in place. If there aren't any screws you can make use of a screwdriver and wedge it between the cover plate and the hidden screws plate and then remove it.
After removing the old knob examine it for signs of rust and damage. If the knob shows any marks or scratches then you'll need clean it. Otherwise it shouldn't require any major work.
Now it's time to install the new one. Before you do that, look over the new knobs to ensure you're selecting the correct one for your door. You'll want to pick one with an extending rod that is designed to lock with the second knob's rod mechanism. After you've inserted the new knob in the hole and then put it in the latch.
Thread the latch plate screws down, then test the spring by pressing down on it several times. The latch should spring back up every time. Then, you can install the new knob and lock it with the rod mechanism of the first knob. Thread in the other long screws from the interior knob through the cylinder hole on the doorknob on the outside and secure it.
Latch
A latch is a steel piece that extends out into the doorjamb to keep it closed. The latch can be operated via a knob or handle on the interior of the door, or a thumb-turn on the exterior. A deadbolt can be used to secure a latch and keep intrusions from breaking through the glass of the door. It also provides protection from accidental or intentional closing of the door by pets or children. replacement upvc door locks repairmywindowsanddoors.co.uk can be set with single cylinder deadbolts or double cylinder deadbolts, depending on the security level you prefer.
Installing a deadbolt is exactly the same as installing a latch, however there are some differences. First, measure the setback of the doorjamb using 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 you have a greater setback, you might need to purchase a larger latch from a hardware shop or locksmith.
The next step is to drill an edge bore hole through the doorjamb for the latch plate. Use a chisel and chisel the latch mortise. Make sure the hole's depth is sufficient for the faceplate to be in line with the doorjamb. Place the strikeplate on the floor to ensure it's placed properly.
If the strike is positioned too high, the door can be pushed into or pressure applied to it using a crowbar, or tire iron. This can also cause the doorjamb to break. To correct this, the strike can be reduced by drilling a second hole in the doorjamb and cutting out the core of the hole that was previously drilled.
The last step is to put in the new strike plate which is done by screwing it in place over the existing screw holes. Then, use wood putty to cover the holes from the previous screws and the bolt hole that won't be used. Once the putty is dry then sand it to a smooth finish for professional results.
Strike
The metal piece that engages the latch and deadbolt when the door is closed is an electric strike. It is an important part of the security of a lock, as it helps keep the door shut and also provides additional resistance to force or kicks applied to the door. If a door is equipped with an electric strike, it can be opened with an entry key or the control unit which controls the electrical impulses.
In the past, putting in an electronic strike was as simple as cutting a portion of a doorjamb in order to release the latchbolt of a cylindrical lock from the pocket inside the strike. This change can be an issue in terms of the appearance of an opening as well as exposing the mechanism of the latchbolt and keeper to unintentional users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" type of strike that doesn't require a cutout to operate. These strikes utilize a special design to allow the keeper and latchbolt to slide into the strike pocket without marring the faceplate of the doorjamb.
The strike is fitted with an internal ramp which lifts the latchbolt as well as the keeper when it receives the signal of an individual reader. The latchbolt and keeper are pushed on the ramp thanks to the retraction. When the door is closed the deadbolt remains retracted, and the latchbolt is retracted into the keeper.
Installing an electric strike is an easy process, particularly when you are replacing an existing strike door. If, however, you are upgrading to an electric strike for an access control system, you will 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 wired to your access control system and is configured for fail-safe operation.
One method to guard against unauthorized access is to upgrade the strike on your doors to a heavy-duty strike plate. The plates are made of up to six screws of three inches instead of the standard two screws of three-fourths of an inch. These screws are longer, making it more difficult for anyone to break the frame and reach inside to turn the thumb turn part of a single cylinder deadbolt.
