How to Replace Door Locks Door locks are your first protection against unauthorised entry into your home. Signs of wear and tear, as well as instances like moving into a new residence or burglaries, could trigger the necessity of replacing your lock. 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 enable you to purchase the correct-sized lock. Deadbolt Installing a deadbolt can be a ideal way to secure 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 into the door. A single cylinder deadbolt is activated using keys on the exterior side and a thumb turn part on the inside. Deadbolts are only effective if it's installed correctly, though. First, you must determine whether the door already has a hole that is suitable for a deadbolt, or if you need to drill it out. Using the template that comes with your lock installation kit, mark the location of the deadbolt hole on the door's surface. Then, use the tape measure to determine the height the deadbolt needs to be. Then, mark the high point on the outside of the door. Use a speed square to draw straight lines across the mark you made for the bolt hole. Then, using an electric drill, bore out the hole until it is on the opposite side of the door. It could take a few minutes. Sand the hole and edge of the door to make it smooth. At this stage, it's a great idea also to paint or stain your door. Once the door is ready, remove any screws that are visible on the existing deadbolt. This will reveal the rear and front assembly of the deadbolt and its bolt inside. Then, remove the bolt and replace it with a new one that is compatible with the door hardware. The bolt is usually attached to a set plate which you'll have to remove. After this, you'll need to chisel the surface of the door frame for the strike plate. If your strike plate is not aligned, it's likely because the previous installer didn't properly mortise it or a weatherstripping came along and changed the strike's position. To fix this issue, you will need to remortise the strike plate as well as the deadbolt. Once this is completed Test the deadbolt by closing it and locking it. Be sure the bolt is extending into the strike plate then test the key to ensure it is able to open and close effortlessly. Knob If the knob on your door is damaged it could make your business or home less secure. It can also make opening or closing the door more difficult, which is why it's an ideal idea to replace it. Replacing knobs is an simple DIY project that shouldn't take more than 30 minutes to complete. You can use a screwdriver or pliers to get rid of the knob or handle Be careful not to harm any of the other components on the door. Spray WD-40, or another dry lubricant, on the mechanism of your door knob prior to you begin. This will assist the new lock to move smoothly when you turn it. It's important to use a quality knob and handle that match your doors currently in order to ensure proper operation. If you don't already have a doorknob that is compatible then you'll have to purchase a new one. Before you begin the replacement, examine the old knob to see what screws are holding it in place. If there aren't any screws you can use a screwdriver to insert between the cover plate and the plate with hidden screws and then remove it. After taking the knob off examine it for indications of damage and rust. If the knob is damaged or has scratches or marks, you'll have clean it. Otherwise, it shouldn't require any major work. Install the new knob. Before you do that, look over the two new knobs to make sure that you're choosing the right one for your door. You'll want to pick one with an extended rod that's designed to lock into the second knob's rod mechanism. Once you've put the new knob in the door's hole and then carefully place it in the latch. Test the spring by pressing it down repeatedly. The latch should rise every time. Install the second knob and secure it to the rod mechanism of the first knob. Thread the long screws from the interior doorknob into the holes for the cylinder on the exterior knob and fix it in place. Latch A latch is a piece of metal that extends through the doorjamb to hold it closed. It is operated with a knob or handle on the interior side of the door or a thumb turn on the exterior side of the door. A deadbolt is a device used to secure a latch and prevent burglars from piercing the glass of the door. It also protects against accidental or intentional closing of the door by children or pets. The latch can be fitted with a single cylinder deadbolt or double cylinder deadbolts based on the level of security you prefer. Installing replace upvc door lock Repair My Windows And Doors follows the same steps as installing a deadbolt, however, there are a few distinctions. First, determine the setback of the doorjamb by 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 center of the hole to accommodate the faceplate of the latch. A standard setback is 2 3/8 to 2 ¾ inches. If your setback is higher it is possible to purchase an extra-long latch from a hardware or locksmith store. Then, you'll need to drill a hole for the latch plate in the doorjamb's edge. Utilize a chisel to smooth out the latch mortise and ensure it's deep enough to allow the faceplate of the new latch to sit flush with the doorjamb. Tape the strike plate in place to ensure that it is positioned correctly. If the strike is positioned too high, the door could be kicked in or pressure put on it with a crowbar or tire iron. This can also crack the doorjamb. To correct this, the strike could be lowered by drilling another hole into 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 over the screw holes that are already in place. Then you can use wood putty to cover the screw holes that were previously used and the bolt hole that will not be used. After the putty has dried then sand it to an even finish. Strike An electric strike is the metallic part where the deadbolt and latch are engaged when the door is closed. It is an important part of the overall security of a lock since it helps keep the door shut and also provides additional resistance to force or kicking applied to the door. If a door is equipped with an electronic strike, it will be opened only by an entry key and a control unit that regulates its electrical impulses. Traditionally, installing an electric strike involved cutting out a portion of the doorjamb to remotely release the latchbolt of a cylindrical lock from the pocket in the strike. This change can be an inconvenience in terms of the appearance of an opening, and it also exposes the latchbolt and keeper mechanism to any unauthorised users. Recently, several electric strikes manufacturers have developed a “No Cut” kind of strike that does not require a cutout for operation. The strikes use a unique design to allow the keeper and latchbolt to slide into the strike pocket without damaging the faceplate of the doorjamb. The strike is equipped with an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a controller or reader. The retraction of the keeper and latchbolt raises them on the ramp, which locks 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 simple process, particularly in the case of replacing an existing strike. However, if you are upgrading to an electric strike in an access control system, you'll have to ensure that your new system is compatible with the model of lock you have installed. Also, you must ensure that the strike is connected to your access control system and is configured to operate in a fail-safe manner. Upgrade your strike plates to high duty strike plates to block unauthorized entry. These plates are fitted with four to six three-inch screws instead of the two, three-fourth inch screws that are typically used in regular strikes. The longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt for a cylinder more difficult.
