You may want to replace your lock for a variety of reasons, for instance, when you suspect that someone else holds the key or if you've got an incoming roommate. In any event, you could save money by taking the lock off yourself rather than paying a professional to do it. The process is easier than most people think and can be done in a few minutes. Start by removing the handle and trim from the door. With a flat screwdriver, remove the trim. It should be possible to pull off the majority of it. In certain cases you may be able to remove the handles completely. The next step is to look for a hole on the inside of the handle and insert an unstraightened clip into it. This will activate the release mechanism and allow you to take the handle from the door. Then, look on the inside of the lock for a small tab and press it using a screwdriver that is flat.

Consider different kinds of locks, and find one that matches your door's style. Consider the backset (the distance between the edge of the door and the center of the hole for the lock) and the cross bore (small hole in the frame of the door frame). Select a lock that is suitable for the door thickness and swing. The American National Standards Institute and BHMA have graded all locks for doors to give you an idea of their longevity and the difficulty to pick them or disable them.

Replacing the cylinder It is easy to replace a damaged or broken door lock cylinder with an easy DIY project. The trick is to select the right cylinder and follow the directions that are included with it. First, you must remove the knob or handle, if it is present. Then, using a screwdriver, take off the trim around the lock cylinder. After the trim has been removed, it is possible to remove the screws holding the cylinder in place using a flathead. The cylinder is then gently removed away from the door. Make sure you measure the length of your new cylinder prior to installing it. With a tape measure, measure the distance between the center of the cylinder and the right and left sides. Purchase a new cylinder which has the same measurements. This will prevent cylinders from snapping when the door is kicked or the key gets stuck inside. If you have a replacement cylinder, put it into the door and turn the key. This will align the cylinder with the carriage that is usually located on the outside of the lock. Then, loosen the set screws which should be a couple of turns in the head. If there is a screw at the exterior of the case that holds the door, you'll have to loosen it. You can replace the lock cylinder you have used with a new one by slipping it into the case, and then tightening the set screws. Installing the part that connects a cylinder with a lock indicator stem is also essential. You can do this by pulling three tabs on the back of the cylindrical with needle-nosed pliers. Then, you can attach the remaining smaller bracket to the back of the cylinder. Then, you must put back in the strike plate and latch plate, as well as the retaining ring that is connected to the top of the lock cylinder. Installing a new lock If you're replacing an existing lock, start by measuring the width of the door. Most locksets for residential use come with a thickness of 3/8 inch to 1 ¾ inches. If your door is thicker than 1 3/8 to 1 ¾ inches, you'll need an extra thick door kit. This would include longer screws and either an extended spindle extension or tail piece for door knobs. Most locks come with a detailed instruction booklet to guide you through the installation of the new hardware. Take the time to read the instructions before beginning the process to ensure that you are following all of the necessary steps. The manual will also give you an idea of the level of skill required to complete the task. It is possible to ask a friend who has worked with locks for help if you are changing a lock the first time. It's a great idea seal the openings of the old hardware before installing the new lock. This will stop the screws from slipping through the holes, and also protect any tiles you may have installed. It also shields your tiles from damage caused by dirt, rust and grime. SECURAM Touch comes with a strip painter's tape designed to be used for this purpose, however you can also use gaffer's or masking tape if you have it available. Once you've removed the screws that hold the interior portion of the lock section to the exterior side, pull it straight away. It is important to do this as quickly as possible so that the lock doesn't end up closing itself in a way that could end up damaging the mechanism. If your new lock has an internal latch bolt, insert the new bolt into the upper cross bore. Make sure you place it in the right position that is usually indicated by an indication on the faceplate. Then, you can screw the latch plate onto the bolt. Screw the deadbolt to the door jamb. Test the deadbolt a few times by throwing it to see if it extends into the strike plate. If you're using an electronic smart lock, make sure to follow the included instructions to program it. This involves downloading an application and creating an email address, confirming your identity, and accessing the wireless network to add your device.
