Replacing door handles is a simple DIY project that can quickly enhance the appearance and convenience of a room. Whether you upgrade, repair damaged mechanical devices for aesthetic reasons, or enhance safety, the operating process is roughly the same for most standard indoor doors. Just prepare some common tools and spend about 30 minutes to confidently complete this task.
-New Lever Handle Set: Ensure it's designed for your door's thickness (usually 35mm or 40mm in the UK/Europe) and has the correct backset (the distance from the edge of the door to the centre of the handle, typically 60mm).
-Screwdriver (Phillips and Flat-Head): A multi-bit screwdriver is ideal.
-Allen Keys (Hex Keys): Usually provided with the new handle.
-Tape Measure (Optional): To double-check backset.
-Masking Tape (Optional): To protect the door from scratches.
1. Find the operating hole: Most modern lever handles have a small and usually hidden hole on the decorative panel at the bottom or around the handle. This hole is designed for easy removal of the handle.
2. Release the lever: Insert a small Allen key (included with the new handle) or a thin and hard metal wire (such as a straightened paper clip) into this hole. Push inward forcefully. You should be able to feel a spring-loaded device pressing down. While maintaining this state, pull the lever handle directly off the shaft. It should slide down with a little shaking. Some older models may have a small fixing screw on one side of the lever; If that's the case, just use an Amway screwdriver to loosen this screw.
3. Remove the Rosette/Backplate: With the lever removed, you will see the main rosette or backplate. This is typically held in place by two long screws that run through the entire door, connecting the handle on the other side. Use your screwdriver to completely unscrew and remove these two screws.
4. Separate the Two Sides: Once the screws are out, both sides of the handle assembly will be free. Gently pull them apart and out of the door.
1. Check the structure of the door: After removing the old door handle components, you will see the square shaft (used to rotate the door lock) and the door lock itself. Normally, unless your newly installed handle requires a different style (such as different surface treatments or door locks with different opening lengths), there is no need to replace the door lock.
2. Compare new latch (if replacement is required): If your new handle comes with a new latch, compare it with the old latch. If they are of the same size and type, you can use a new latch to achieve a consistent appearance. To remove the old door latch, simply unscrew the two screws fixed to the edge of the door and pull it out.
3. Install a new lock buckle (if needed): Slide the new lock buckle into the hole on the edge of the door, ensuring that the inclined surface of the lock buckle tongue faces towards the direction of door closure. Secure it with the provided screws.
This process is essentially the opposite of the removal operation.
1. Insert the shaft: Remove one side of the new handle and find the part connected to the lock buckle. For most handles, this requires inserting a square shaft through the hole on the locking device.
2. Fix the first side: Place the handle side inside the door. Usually, it is more convenient to have an assistant secure this side of the door from the other side.
3. Connect the second side: Hold the other side of the handle and align it with the part now protruding from the door. Ensure that the screw holes are aligned. Leverage should be in a horizontal (or neutral) position.
4. Fixed components: Thread two long connecting screws through the screw holes on one side and start screwing them into the receiving holes on the other side. Do not overtighten at present. When both screws have started to rotate, tighten them alternately to ensure that both sides are evenly pressed against the door surface, while avoiding misalignment of the handle. The handle should be tightly attached to the storefront without any shaking.
5. Install the lever: Align the lever with the shaft or mounting point. For handles with openings, simply push the lever onto the shaft until a clear "click" sound is heard or felt (at this point, the internal fixing clip is fully secured in place). If there is a fastening screw on the handle, cover the lever and tighten the screw to a secure position with an Allen key.
1. Operating handle: Please test this lever multiple times to ensure that it runs smoothly and can accurately return to a horizontal position.
2. Check the latch: Open and close the door to confirm that the latch can be inserted and ejected normally without any jamming.
3. If necessary, tighten: If the handle is shaking, you may need to loosen the long screw slightly, readjust the position of the handle to make it more secure, and then tighten it again.
1. Loose handle: This is usually due to two main connecting screws becoming loose. Please tighten them further.
2. Failure to retract the locking mechanism: This usually means that the square shaft is not properly engaged with the locking mechanism. When disassembling, please ensure that the shaft can drive the lock buckle to rotate when operating the lever.
3. Scratches on the door: During installation, use tape around the back cover area to protect the surface of the door.
4. Keep the components neat and orderly: When removing the old handle, place the screws and small parts into a bowl to avoid loss.
Follow the steps below to successfully replace the lever handle on the door, giving your door a safe, practical, and brand new appearance. This is a simple upgrade that can bring excellent results in terms of aesthetics and daily use.
