How to Replace Door Locks

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 purchase the appropriate lock.
Deadbolt
Installing a deadbolt can be a excellent way to protect your door from burglars. The bolt extends into the strike plate on the door frame when it's locked, making it much more difficult for a burglar to gain entry through the door. A single-cylinder deadbolt can be activated with a key on the outside and a thumb-turn piece situated inside. Deadbolts can only function when it is properly installed.
You will first need to determine whether the door already has an existing hole for a deadbolt, or if you'll need to bore it out. Using the template that comes 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 high point on the door's edge, and then use speedsquares to draw a straightline across the mark that you made to mark the bolt hole.
Then by using a power drill, bore through the hole until it is on the opposite side of the door. It may take a while. Then, sand the hole and the edges of the door until it's smooth. It's also an excellent idea to paint or stain the door at this point.
Remove any screws that are visible from the deadbolt. This will reveal the front and back assemblies of the deadbolt, and also the bolt that is inside. Then unscrew the old bolt and replace it by an alternative bolt that matches the door hardware. You'll need to remove the bolt from a setplate. Then, you'll need to chisel the surface of the door frame to accommodate the strike plate.
If your strike plate isn't aligned properly, it's likely because the previous installer didn't properly mortise it or a weatherstripping was installed and changed the strike's position. To correct this issue it is necessary to remortise the strike plate and the deadbolt. Close and lock the deadbolt after you've completed this process. Test the deadbolt by closing it and locking it after the bolt has been extended into the strike plate.
Knob
It can make your home and business less secure If the knob on your door is worn. It may make it more difficult to open or close the door, so it's an ideal idea to replace it. Replacing a knob is a relatively simple DIY project that shouldn't take less than 30 minutes to complete. You can use a screwdriver as well as pliers to get rid of the knob or handle However, be careful not to damage any of the other components on the door.
Before you begin you'll need to spray WD-40 or a different dry lubricant on the mechanism of the door knob. This will assist the new lock move smoothly when you turn it. To ensure that it operates properly it is important to select the knob and handle that are compatible with your doors. If there's no match, you'll need to buy a replacement doorknob and latch plate.
To begin the replacement process, look at the 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 remove it.
Once you've removed the knob, check it for any indications of damage or rust. If the knob has any scratches or marks, you'll have to clean it. Otherwise it shouldn't need any major work.
Install the new knob. You must first study the two knobs to ensure that you've chosen the right one for the door. You'll need to pick one with an extended rod that locks with the rod mechanism of the second knob. Once you've put the new knob in the hole in the door and then carefully insert it into the latch.
Thread the latch plate screws downwards and then test the spring by pressing down repeatedly. The latch should rise every time. Install the second knob, and lock it to the rod mechanism of the first knob. Attach the other long screws from the interior knob through the cylinder hole on the doorknob on the outside and lock it in place.
Latch
A latch is a metal piece that extends into the doorjamb to keep it closed. It is operated by a knob or handle on the interior side of the door or a thumb turn on the outside side of the door. A latch can be secured with a deadbolt to keep thieves from breaking through the door's glass. It can also guard against accidental or intentional closing by pets or children. You can install an entry point with either a single-cylinder or double-cylinder deadbolt, depending on the level of security.
Installing a latch requires the same steps similar to installing a deadbolt but there are a few distinctions. First, measure the setback of the doorjamb using a tape measure to make sure the new lock will fit. The setback is the distance from the edge of the doorjamb to the middle of the hole to accommodate the faceplate of the latch. A typical setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you might need to purchase a more substantial latch at a hardware store or locksmith.
The next step is to drill an edge bore hole through the doorjamb for the latch plate. Use a chisel and make the mortise for the latch. Make sure that 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 set too high, the door may be pushed into or pressure put on it using a crowbar, or tire iron. This can also cause the doorjamb's to crack. This can be fixed by drilling a new hole in the doorjamb, then cutting the core from the previous one.
The last step is to install the new strike plate which can be done by screwing it in place over the screw holes that are already in place. Use wood putty afterwards to fill in any existing bolt holes or screw holes that aren't being used. Once the putty is dry, sand it smooth for a professional finish.
Strike
upvc door locks replacement is the metal piece where the latch and deadbolt engage when the door is closed. It is a vital component of the overall security of a lock because it keeps the door shut and provides extra resistance to kicking or force applied to the door. If a door is fitted with an electronic strike, it can be opened only with keys and the control unit that controls its electrical impulses.
In the past, installing an electronic strike was as simple as cutting a portion of a doorjamb, which would remove the latchbolt on a cylindrical lock from the pocket within the strike. This is not only undesirable however, it also exposes the mechanism for the latchbolt and keeper to unauthorized users.
Recently, a number of electric strike manufacturers have created an innovative type of electric strike called the "No Cut" strike that doesn't need an opening in the doorjamb to operate. These strikes have a unique design that allows the latchbolt and keeper to slide into the strike pocket without marring the faceplate of the doorjamb.
The strike has an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a reader or controller. The retraction of the keeper and latchbolt raises them on the ramp, thereby locking the door. When the door is closed, the deadbolt stays at a lower position and the latchbolt retracts into the keeper.
Installing an electronic strike is a straightforward process, particularly in the case of replacing an existing strike. However, if you're upgrading to an electric strike to use with an access control system, you'll be required to ensure that the new system is compatible with the type of lock you have installed. It is also necessary to ensure that the strike is connected to your access control system and is set up to function in a fail-safe way.
One method to guard against unauthorized access is to upgrade the strike on your doors to a heavy-duty strike plate. These plates use up to six screws of three inches instead of the standard two screws of three-fourths of an inch. The longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt for a cylinder more difficult.
