How to Replace Door Locks
Door locks are your primary line of defense against unauthorized access to your home. The locks may need to be replaced due to wear and tear or other circumstances like moving into a new home or a burglary.
You can determine the size of your cylinder by measuring the distance from the center of the knoblock cylinder to the adjustment screw. This measurement will allow you to select the appropriate lock.
Deadbolt
Installing a deadbolt can be a ideal 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 through the door. A single cylinder deadbolt can be activated by an exterior key on the side and a thumb turn part on the interior. Deadbolts can only function when it is properly installed.
First, you'll need to find out if the door has a hole to install a deadbolt or if it needs to be bored out. Mark the location of the hole to install the deadbolt on the exterior of the door using the template included with the lock installation set. Use your tape measure to determine the height of the deadbolt. Then, mark this high point on the outside of the door. You can then use the speed square to draw an even line across the mark you made for the bolt hole.
Then using a power drill, bore through the hole until it is on the opposite side of the door. This could take a while. Sand the hole and the edge of the door to smooth it. At this stage, it's a great idea also to paint or stain your door.
Remove any visible screws from the deadbolt. This will reveal the back and front assemblies of the deadbolt, and also the bolt that is inside. Remove the bolt and replace it by an alternative bolt that matches your door hardware. You will need to unscrew the bolt from a setplate. After this is done, you will need to chisel the area for the strike plate on the door frame.
If your strike plate is not aligned, it's likely because the previous installer didn't correctly mortise it or a weatherstripping came along and altered the strike position. To fix this problem you'll need to remortise the strike plate and the deadbolt. Once this is completed Test the deadbolt by closing it and locking it. Make sure the bolt is extending into the strike plate then test the key to ensure it closes and opens smoothly.
Knob
If a door knob wears out it could make your business or home less secure. It could also make it harder to open or close the door, which is why it's an ideal idea to replace the knob. It shouldn't take you longer than 30 minutes. You can use a screwdriver or pliers to take off the knob or handle Be careful not to damage any other parts on the door.
Spray WD-40, or a different dry lubricant, onto the mechanism of your door knob before you begin. This will help the lock to move effortlessly as you turn it. To ensure that it operates properly, it's important to choose the right knob and handle to match your existing doors. If you don't already have a matching doorknob then you'll have to purchase a replacement.
To begin the replacement process, look over the knob or handle to see what screws are holding 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 pop it off.
After you have removed the knob examine it for signs of rust and damage. If the knob shows any marks or scratches it's time clean it. Otherwise, it shouldn't require any major work.
Install the new knob. Before you do that, look over the knobs you've chosen to make sure that you're selecting the correct one for your door. You should select one with an extending rod that is designed to lock with the rod mechanism on the second knob. Once you've put the new knob into the hole, slide it into the latch.
Test the spring by pressing it repeatedly. The latch should rise every time. Then, you can install the new knob and connect it with the rod mechanism on the previous knob. Attach the other long screws from the interior knob through the cylinder hole on the exterior doorknob and secure it.
Latch
A latch is a metal piece that extends into the doorjamb to keep it closed. It is operated with a knob or handle on the inside of the door or a thumb turn on the outside side of the door. Deadbolts can be used to secure a latch and stop intruders from breaking through the glass of the door. It also provides protection from accidental or intentional closing of the door by pets or children. A latch can be set using single cylinder deadbolts or double cylinder deadbolts according to the security level you prefer.
Installing a deadbolt is exactly the same as installing a latch however, there are some distinctions. To make sure that the new lock is compatible, first take a measurement of the setback on the doorjamb using a tape measure. The setback is measured from the edge of doorjamb up 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 larger setback, you might need to purchase a larger latch from a hardware store or locksmith.
The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Use a chisel and chisel the latch mortise. Make sure that the depth is sufficient for the faceplate to be in line with the doorjamb. Put the strike plate into the correct position to ensure it's placed correctly.
If the strike is positioned too high, the door could be pushed into or pressure put on it with a crowbar or tire iron. This can also crack the doorjamb. This can be fixed by drilling a new hole in the doorjamb, and chiseling the core out of the previous one.
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 old bolt holes or screw holes that won't be used. Once the putty has dried you can sand it until it has a smooth finish.
Strike
An electric strike is the metal piece that holds the latch and deadbolt engage when the door is closed. It is an essential component of the lock's overall security, as it prevents the door from opening, and also provides an additional level of resistance to force or kicking. If a door is equipped with an electronic strike, it can be opened only with an entry key and a control unit that regulates its electrical impulses.
In the past, putting in an electronic strike was as simple as cutting off a part of a doorjamb, which would let the latchbolt of a cylindrical lock from the pocket that is inside the strike. This modification can be an issue in terms of the aesthetics of an opening and also exposes the mechanism of the latchbolt and keeper to unauthorized users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" type of strike that does not require a cutout in order to operate. They use a specific design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate.
The strike has an internal ramp which lifts the latchbolt and keeper whenever it receives a signal from a reader. cost to replace upvc door lock mechanism and latchbolt are lifted higher up the ramp by the retract. When the door is closed the deadbolt remains retracted, and the latchbolt is retracted into the keeper.
Installing an electric strike can be a simple process, especially when you are replacing the strike on a previous door. If you're planning to upgrade an access control system to an electric strike, it is important to ensure that the new system is compatible. Also, you must ensure that the strike is properly connected to your access control system and is configured to function in a safe manner.
Upgrade your strike plates to heavy duty strike plates to prevent unauthorised entry. These plates use up to six screws of three inches instead of two screws of three-fourths inches. These longer screws make it harder for anyone to break the frame and then reach inside to turn the piece that turns the thumb of a single deadbolt cylinder.
