How to Replace Door lock Door Locks
Door locks are your primary protection against unauthorised access to your home. Locks may require replacement due to wear and tear or other circumstances like moving into a new residence or a break-in.
To begin, you must determine your cylinder size by measuring the distance between the adjustment screw and the center of the cylinder knob. This measurement will enable you to buy the right lock.
Deadbolt
Installing a deadbolt can be a excellent way to protect your door from burglars. The bolt extends into the strike plate that is on the doorframe when locked, making it more difficult for burglars to gain entry into the door. A single-cylinder deadbolt is activated with a key on the exterior, and a thumb-turn device that is located inside. A deadbolt will only work only if it is correctly installed.
First, you will need to determine if the door already has a hole for deadbolts, or if it has to be bored. Mark the location of the hole for the deadbolt on the surface of the door using the template included with your lock installation kit. Then, you can use your tape measure to determine how high the deadbolt should be. Then, mark the height on the side of the door. You can then use the speed square to draw a straight line across the mark you made for the bolt hole.
Then by using the power drill, drill out the hole until it is on the opposite side of the door. This may take a while. Then, sand the hole and the edges of the door until it is 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 rear and front assembly of the deadbolt as well as its bolt inside. Then, unscrew the bolt and replace upvc door lock mechanism it with a brand new one that matches your door hardware. It is necessary to remove the bolt from a setplate. After that, you'll have to chisel the area on the replace door lock frame to accommodate the strike plate.
If your strike plate is misaligned, it's likely because the previous installer didn't correctly mortise it or a weatherstripping came along and altered the strike position. To correct this issue, you will need to remortise the strike plate and the deadbolt. Close and lock the deadbolt once you've completed this step. Make sure that the bolt is extending into the strike plate then test the key to ensure it is able to open and close smoothly.
Knob
If the knob on your door is damaged, it can make your home or business less secure. It could make it more difficult to open or close the door, making it a good idea to replace upvc door lock mechanism it. Replacing knobs is an easy DIY project and shouldn't take longer than 30 minutes to complete. Use pliers or a screwdriver to take off any knobs or handles. Be cautious not to damage the other components of the door.
Spray WD-40, or another dry lubricant on the mechanism of your door knob before you begin. This will allow the new lock to 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 match then you'll have to purchase a new doorknob and latch plate.
Before you begin replacing the knob, look over the knob you replaced to determine what screws are that are holding it in place. If there aren't any screws you can use a screwdriver to wedge between the cover plate and the plate with hidden screws and remove it.
Once you've removed the knob that was previously used, look it over for signs of damage or rust. You'll have to scrub it off if there are any marks or dents however, you shouldn't need to do anything major if the knob is in good shape.
Now is the time to put in the new one. Begin by examining the new knobs to make sure that you're choosing the right one for your door. You should select one that has an extending rod that's designed to lock into the second knob's rod mechanism. Once you've put the new knob over the hole in the door and then carefully place it in the latch.
Thread the latch plate screws down and test the spring by pressing down on it repeatedly. The latch should spring up every time. Next, install the other new knob and lock it with the rod mechanism on the first knob. Thread the long screws of the doorknob's interior through the holes for the cylinder on the outside knob and fix it in its place.
Latch
A latch is a metal piece that extends into the doorjamb to keep it shut. It is operated by a knob or handle on the inside of the upvc door lock replacements or by a thumb turn on the outside side of the door. A deadbolt is a device used to secure a latch and keep intrusions from breaking through the glass of the door. It can also protect against the accidental or deliberate closing by pets or children. You can choose to install an entry point with either a single-cylinder or double-cylinder deadbolt based on the level you prefer for security.
Installing a latch involves the same steps like installing a deadbolt but there are a few distinctions. To make sure that the new lock will fit first, take a measurement of the setback on the doorjamb with the tape measure. The setback is the distance between the edge of the doorjamb to the middle of the hole to accommodate the faceplate of the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a greater setback, you may have to purchase a longer latch from a hardware shop or locksmith.
Next, make a hole for the latch plate in the edge of the doorjamb. Use a chisel and make the mortise for the latch. Make sure the depth is enough for the faceplate to be in line with the doorjamb. Place the strikeplate on the floor to ensure that it's positioned properly.
If the strike is set too high, the door may be pushed in or pressure applied to it with a crowbar or tire iron. This can cause the doorjamb to crack. This can be corrected by drilling a new hole through the doorjamb, and removing the core from the old one.
Installing the new strike plate is the last step. This can be done by fixing the new plate to 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 is not used. Once the putty is dry you can sand it down to give it a a professional finish.
Strike
The piece of metal that is inserted between the latch and deadbolt when the door is shut is an electric strike. It is an essential part of the lock's security because it stops the door from opening and provides additional resistance to force or kick. If a door has been equipped with an electric strike, it can be opened using an entry key or the control unit that governs its electrical impulses.
Traditionally, installing an electric strike involved cutting a small portion of the doorjamb to remotely release the latchbolt of a circular lock from the pocket of the strike. This modification is not only ugly and unattractive, but also exposes the mechanism of the latchbolt and the keeper to intruders.
Recently, several electric strike makers have come up with an innovative type of electric strike dubbed the "No Cut" strike that doesn't require cutouts in the doorjamb to function. These strikes utilize a special 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 raises the latchbolt and keeper whenever it receives an electrical signal from a controller or reader. The retracting of the keeper and latchbolt causes them to rise on the ramp, locking the door. When the door is shut the deadbolt remains in retracted and the latchbolt retracts into the keeper.
Installing an electronic strike is a simple process, particularly in the case of replacing lock in upvc door an existing strike. If, however, you are upgrading to an electric strike to use with an access control system, you'll need to make sure your new system is compatible with the type of lock you've installed. You will also need to ensure that the strike is wired to your access control system and that it is set up for fail-safe operation.
One way to protect against unauthorized access is to upgrade the strike on your doors to a heavy-duty strike plate. These plates are fitted with four to six screws of three inches instead of the two, three-fourth inch screws that are typically employed in regular strikes. These screws are longer, making it difficult for someone to break the frame and reach inside to turn the piece that turns the thumb of a single deadbolt cylinder.
