Front Door Lock Barrel Replacement Front door lock barrel replacement is a relatively simple DIY job that will save you the cost of calling out a locksmith. You can buy kits that include all the tools you require. You will need to purchase a new cylinder-lock barrel, a screwdriver set that is solid, a hammer or pliers for more grip and the lubricant. Length There are a variety of lock barrel options to choose from to ensure that your front door is safe. When choosing the type of lock barrel you want to purchase the length of the cylinder can be critical to the security of your home. Cylinders that are too long are more likely to snap, and those which are too small may hinder you from turning your key to unlock the doors. There are several methods to determine the length of a cylinder, so that you can buy a replacement cylinder that will provide maximum security for your door. To determine the correct size of the cylinder, remove the old cylinder from the door. Remove the screws holding the lock cylinder. After the cylinder has been removed, you can measure from the center screw hole of the cylinder to edge of the handle plate that is on the inside of the door. Be sure to include the thickness of the plate as well. You can also take a measurement of the length of the threaded shaft that is on the new cylinder to determine the size. After determining the length of the cylinder, you can then place it in your door. Start by drilling a hole into the door. This is where the handle or knob will go, and it should be slightly larger than the diameter of the new cylinder. Afterward, attach the interior handle or knob to the handle you want to replace and make sure it passes through the spindle of the latch, and turns smoothly when you turn it. If you are replacing a deadbolt, you should also consider upgrading your strike plate. The strike plate is the metal piece that mounts to the doorjamb and locks into the bolt once it's forced in by a key. It's crucial to replace the strike plate with one that is more difficult to breach. Find a strikeplate with a reinforced metal structure to resist kick attacks. Make sure to use screws that are at minimum 2.5-3 inches long to ensure they penetrate deeply into the doorjamb. Design The lock cylinder is part of the front door lock that you utilize to open or close the handle. It is equipped with pins that move into position when you insert the key. It is important to be aware of a few points when it comes to selecting the appropriate lock cylinder. For example, it's important to determine the length of your current lock to ensure you purchase the correct size. You'll also need to take into account any door furniture, such as handles or escutcheons. Euro Cylinder locks come in a variety of designs. Some are double cylinder locks, which offer security from both sides of the door. They are commonly used on doors that need more security than regular locks, and also in some commercial buildings. Check that the lock you're considering is British Standards approved, and has the following requirements: Anti-Snap: A burglar may attempt to snap a cylinder by applying pressure to the exterior of the door. To stop this from happening, the lock should have a thin sacrificial line that's cut into the cylinder body. Anti-Drill: Some burglars are able to drill through the lock in order to gain entry into a house. To guard against this, a cylinder should have pins made of hardened steel. When you are looking for a new cylinder you must also ensure that it's anti-drill. This will stop burglars from ripping the plug out by drilling into it with the power tool. Once you've selected the cylinder lock you want, you will need to gather all of the components you'll need to put it into place. Included in this is an appropriate screwdriver for the task, a hammer for extra grip and pliers. You should also have some fluid to ensure that the mechanism is operating smoothly. Before you begin, be aware that changing the barrel of a lock on the uPVC door can be a challenge. If you're not confident in doing it by yourself, it's recommended to call a locksmith or specialist for assistance. Keyway The keyway on locks is the shape of the connection between the cylinder and the key. The key has a set of ridges and grooves that run down the length of its “blade”, and when inserted, these coincide with the cutouts in the cylinder's pins. The cylinder is able to move if it is sure that it is the correct one. Each brand of lock has a unique keyway that allows it to be locked or unlocked with specific keys. There are a variety of keyway sizes and shapes within the same brand. This gives a certain level of security between different locks, as keys from the same brand can't be used to open the locks of another. In the majority of residential settings, the latch is operated using an adjustable lever that can be pushed down or lifted to release the bolt. This is more comfortable than a knob that requires you to turn. However, some commercial settings still use knobs for added security. Once the key that is correct is inserted, the spring-loaded pins move into a position that allows the plug to rotate. The pins are aligned with grooves on the blade of the key and allow the lock to recognize the right key. If the key or cylinder is not inserted correctly, the pins will move to the control shear rather than the operating line. The lock won't open. In this situation it is likely the cylinder has been re-keyed. This involves moving the pins up to the proper height to allow the key to rotate freely within the cylinder. This is common in dormitories where the key for one person might need to be moved between dozens of locks. People often have their locks rekeyed when they move houses or wish to give access to a new roommate or employee without the need to change the locks all to the same key. This is a cost-effective way to improve security for a home. It can be done by simply changing the key for the cylinder. Installation It is simple to change a lock barrel in a uPVC door. The first step is locate the screw under the lock at the edge of the uPVC door. It will usually be noticeable because it is an unusual colour. Then, remove it with an Phillips screwdriver. Then, you can take the new barrel and put it into the last hole. Then, replace the knob with the push rod and barrel. Before reassembling, it is crucial to ensure that all parts are positioned correctly (the barrel and push rod as well as the spring/lever housing). With the help of a screwdriver, you are able to easily remove the handle and knob to gain access to the lock body. Once you have done this the cylinder is rotated counterclockwise in order to loosen it. You can now either remove the cylinder and get it “re-keyed” or leave it in the position it is in. Re-keying does not alter the pins inside the cylinder. replace lock in upvc door repairmywindowsanddoors will simply shift them to the proper location using the key that matches. The other option is simply to take the cylinder off and replace it with a new. If you decide to do this, it is essential to use the same size as your previous cylinder and ensure that the pins are positioned correctly in order for your lock to function properly. It is also an excellent idea to use the lubricant on your new cylinder after installing it to ensure that everything moves smoothly. If you are using a mortise lockset the process will be slightly more complicated. This kind of lock is installed into the pocket (mortise) cut into the side of the door, therefore it will require careful measurement and maybe a few attempts to get the bolt and latch sections to line up. When they do, you will need to take off the strike plate (which is secured by screws that are located on the top and bottom of the door frame) and the latch bolt, which is difficult if you don't have the right tools.
