This measurement will assist you buy the lock that is right for you. Deadbolt If you're looking to ensure that your door is safe from criminals, it's a great idea to install deadbolts. The bolt extends into the strike plate that is on the doorframe when locked, making it more difficult for a burglar to break in through the door. A single-cylinder deadbolt can be activated using a key on the outside and a thumb-turn device located 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 for deadbolts, or if it requires drilling. Using the template that comes with your lock installation kit, mark the location of the deadbolt hole on the door's surface. Then, use your tape measure to determine the height the deadbolt should be. Then, mark the height on the side 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, use a drill to bore out this hole until it extends to 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. At this point, it's a good idea to stain or paint your door. Once the door is ready, remove any screws that are visible on the existing deadbolt. This will reveal both the front and rear assembly of the deadbolt and its internal bolt. Then, unscrew the bolt and replace it with a brand new one that matches the door hardware. The bolt is usually connected to a setplate that you have to remove. After that then you need to cut out the space for the strike plate on the door frame. If your strike plate is out of alignment, it could be because the previous installer did not mortise it properly or that a weatherstripping has changed the strike position. You'll need to re-mortise the strike plate and possibly even the deadbolt itself to correct this problem. After this is done, test the deadbolt by closing it and locking it. Test the deadbolt by closing and locking it after the bolt has been extended into the strike plate. Knob If the knob on your door is worn out it could make your business or home less secure. It could also make opening or closing the door more difficult, so it is recommended to replace it. It shouldn't take more than 30 minutes. Make use of pliers or a screwdriver to take off any knobs or handles. Be careful not to damage other parts of the door. Before you start you'll need to spray WD-40 or a different dry lubricant on the mechanism of the knob for your door. This will help the new lock to slide smoothly as you turn it. It's essential to select an excellent knob and handle that match your current doors to ensure that the lock is operating properly. If you don't already have a doorknob that matches and handle, you'll need to purchase a new one. Before you begin the replacement process, look over the knob you replaced to determine which screws are holding it in place. If there aren't any screws to hold it in place, you can use a screwdriver to wedge the cover plate in between the screws plate hidden behind it. Once you've removed the knob that was previously used, look it over for signs of rust or damage. If the knob shows any scratches or marks then you'll need 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 selected the appropriate one for your door. You'll need to choose one with an extending rod that's designed to lock into the rod mechanism on the second knob. After you've placed the new knob in the hole then slide it into the latch. Thread the latch plate screws down and then test the spring by pushing down on it repeatedly. The latch should pop up every 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 the cylinder on the outside knob and fix it in the knob's position. Latch A latch is a piece metal that extends through the doorjamb to hold it closed. The latch can be operated by a handle or knob located inside the door, or by a thumb-turn on the outside. A latch can be secured by deadbolts to stop intruders from breaking in through the door's glass. It also protects against the accidental or deliberate closing of the door by children or pets. You can install an entry point with either a single-cylinder deadbolt, or a double-cylinder deadbolt, depending on the level you prefer for security. Installing a deadbolt is exactly the same as installing a latch, but there are some differences. To ensure that the new lock is compatible, first take a measurement of the setback on the doorjamb with the tape measure. The setback is measured from the edge of doorjamb all the way to the center of hole for the latch plate. A standard setback is 2 3/8 to 2 ¾ inches. If you have a greater setback, you may need to purchase a more substantial latch at a hardware store or locksmith. Then, make a hole for the latch plate at the edge of the doorjamb. Utilize a chisel to cut the mortise of the latch. Make sure that the depth is enough for the faceplate to be in line with the doorjamb. Put the strike plate into the correct position to ensure it's in the right position. If the strike is set too high, the door can 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 corrected by drilling a new hole through the doorjamb, then removing the core from the hole that was previously made. Installing the new strike plate is the final step. This can be done by fixing the new plate to the screw holes that are already in place. Then, use wood putty to cover the old screw holes and the bolt hole that won't be used. Once the putty is dry you can sand it down to give it a professional results. Strike The piece of metal that connects the latch and deadbolt when the door is shut is an electric strike. It is an essential component of the lock's security because it stops the door from opening and provides an additional barrier to force or kicking. If a door is equipped with an electronic strike, it will be opened only with keys and the control unit that regulates the electrical impulses. In the past, putting in an electronic strike required cutting off a part of a doorjamb to remove the latchbolt on a cylindrical lock from the pocket inside the strike. door lock repairs newbury Repair My Windows And Doors is not only ugly and unattractive, but also exposes the mechanism of the latchbolt and the keeper to intruders. Recently, a variety of electric strike manufacturers have created a “No Cut” type of strike that doesn't require a cutout in order to operate. These strikes use a special design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate. The strike is equipped with an internal ramp that raises the latchbolt and keeper when it receives a signal from an individual reader. The keeper and latchbolt are pushed higher up the ramp by the retraction. When the door is shut, the deadbolt stays at a lower position and the latchbolt retracts into the keeper. Installing an electronic strike is a simple process, particularly in the case of replacing an existing strike. If you are upgrading an existing access control system to an electric strike, you must ensure that your new system is compatible. It is also necessary to ensure that the strike is properly connected to your access-control system and is set up to function in a safe manner. One way to safeguard against access by unauthorized persons 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 usual two screws of three-fourths of an inch. The longer screws make it more difficult for anyone to break the frame and then reach inside to turn the piece that turns the thumb of a single deadbolt cylinder.
