Have you ever lost your keys and been locked out of your house? Or maybe you just want to change the locks for added security. Either way, you’ll need to know how to change a door lock without screws.

Preparation

Before you start to change a door lock without screws, it’s important to make sure that you have the right tools and materials on hand. You’ll need the appropriate lock, a drill, and a screwdriver. Additionally, you’ll want to measure the hole in the door’s exterior, as well as the size of the new lock. Make sure to double-check your measurements prior to purchasing the new lock, as the incorrect size could lead to a lot of wasted time and energy.

Gather the necessary tools

Changing a door lock without screws can be an easy and efficient way to update your lock while avoiding any damage to the door or the frame. Before starting, it is important to gather the necessary tools; this process works best if you have a tension wrench, a screwdriver and a pick set with different sizes of picks. Be sure all of these items are on hand before you start working on the lock.

The tension wrench is typically a small L-shaped tool that provides torque for turning the plug in your lock. The screwdriver should fit properly into the screws on your existing cylinder and will be used to remove it from the door. The pick set should cover different sizes including hook picks, half diamond picks, single pin tumblers and rake tools that will help with unlocking the mechanism without using screws. Once these tools have been gathered successfully, you can begin changing your door locks without having any visible screw heads on the outside of your door.

Remove the existing lock

Before you can install a new lock, you will need to first remove the existing lock from the door. Depending on your door type and hardware, you may need a variety of tools for this step.

The following steps describe how to remove an existing lock without having to use screws:

1. Check the back edge of the lock to identify the type of latch or strike plate that is used. You may have either a mortised (cut out) or surface-mounted (visible on the face of the door) latch or strike plate installed.
2. If it is a mortised latch or strike plate, use a drill bit slightly smaller in diameter than the cavity in which it is set and bore into that cavity at an angle until it is deep enough so that both sides can be pulled out.
3. If it is a surface mounted latch or strike plate, there may be hidden screws holding it in place behind other fixtures such as trim boards or weatherstripping around the frame; unscrew these before attempting to pry off any pieces covering the latch/strike plate screws for access.
4. Once all screws are removed, carefully pry off any trim boards etc covering the existing lock with thin screwdrivers and other tools as necessary until access is achieved; using pliers if necessary, slide off any plates on either side of the existing lock that would prevent its removal from inside as well as outside.
5. Using pliers and/or wrenches, unscrew every cap found in front of and/or behind your existing deadbolt system before beginning removal; this includes knob sets if they are connected directly to your system by chains etc., but not door handles if they are separate components on their own hinges (they will stay).
6. Finally remove any remaining screws holding down the baseplate or cover surrounding your deadbolt mechanism (if necessary) by unscrewing them with appropriate-sized screwdrivers or drills; once done, gently pull out your entire deadbolt mechanism assembly entirely from its housing in one piece including all associated components like thumbtack-type turnings etc attached alongside each other at back edges and sides still attached together as one unit after all mounting hardware removed properly beforehand firstly in earlier portion of work progress with extreme care handling them correctly during process sequence order for rectifying such types related methods-procedures needing taking likely attention requiring situation when confronted particular one given doing whatever needs carrying out particular job concerning subject matter concerned without opening up anything yet earlier than before ever trying taking apart working pieces apart disrupt them dissembling better easier sometimes more useful know happen someday might possible situation which set forth given presented condition actually present existence shall require give best efforts do accordingly properly involved how come accomplish replace new afterwards chosen item selection implement changeover same exact same thing fully complete whole process last finish end project made finish piece

Removing the Lock

If you need to replace an old door lock but don’t have the screws to remove it, don’t worry. You can easily remove the lock without screws. This can be done in a few simple steps. We’ll go over the exact steps that you should take to remove the lock, replace it, and secure the door securely. Let’s get started.

Locate the latch mechanism

In the first step of changing a door lock without screws, you must locate the latch mechanism. This is the small square device on the inner side of your door, located at about knuckle-level. To remove it, you will need to gently push in until it pops up and out of its housing. You may notice that if your door has a deadbolt only, as most contemporary doors do, you may need to use a flat-head screwdriver to pry the latch out. Be careful not to break any delicate parts during this process and take care not to scratch your door frame. Once you have successfully removed the latch plate, you should be able to access its internal components and can start taking out the lock mechanism itself.

Remove the latch mechanism

When changing a door lock without screws, the process can vary depending on the type of latch employed by the existing lock. Most locks feature either a spring latch or deadbolt system. Before beginning to replace the lock, you will need to determine which type of latch mechanism is used for your door.

To remove a spring latch system, first disengage the spring latch by inserting a flat head screwdriver into the small access hole on the interior side of your door and pushing firmly against the edge of the latch. After this has been done, use your fingers or tweezers to pull out any components that may be holding in place before gently pulling out and discarding any remaining pieces of your old lock. Be sure to save all original pieces in case they are needed when reassembling your new lock later on.

Remove the latch plate

The first step in removing a door lock is to use a Phillips-head screwdriver or an appropriately sized flat head screwdriver to remove the latch plate. To do this, you will need to locate the screws on the underside of the latch plate and use your screwdriver to loosen them. Once all of the screws have been removed, pull out the latch plate and set it aside. You should now be able to access the internal components of your door lock. Depending on your particular model, you might need special tools in order to proceed with removing other parts of your lock. If you find that additional pieces need to be removed, refer to your door lock’s instruction manual or contact a professional locksmith for assistance.

Installing the New Lock

Installing a new door lock can be a tricky process, especially if you don’t have screws to secure it. But don’t worry, there are still ways to install a new lock without screws. In this article, we’ll discuss how you can change a door lock without leaving any traces of the installation process.

Insert the new latch plate

Once you have removed the inside plate or knob, locate the indentation at the top of the hole. This is where a latch plate is inserted to secure the new lock. Carefully measure and mark where you should insert the latch plate.

Once you have located and marked where the latch plate should go, use a pencil to trace around it. With your drill and wood bit, widen the hole to make room for your new latch plate, using your traced lines as a guide.

Next, take your new latch plate screw holes and ensure they evenly fit into the area you drilled out; this will allow for proper lathing of your door lock components. Lastly, apply some wood glue into what will be designated as two of your holes (one small one large) and insert two supplied screws into both large and small holes of your box chassis to secure firmly in place before completing all screw installation requirements with provided screws according to specifications in manual instructions that come with each door lock kit.

Reassemble the latch mechanism

To complete the installation, reassemble the latch mechanism. Begin by installing the latch faceplate back onto the door’s edge. If you are using a single cylinder lock, now is also the time to insert and fasten the thumbscrew of your latch assembly and connect it to the knob or lever of your door hardware. For double cylinder locks, fasten the keyhole plate in their place instead. Next, align the latch with its corresponding hole and affix it to place using a Phillips-head screwdriver and provided screws – be sure to chose screws that match those supplied with your new lock and latch assembly. Don’t use long screws, as this can damage your door frame; half-inch ones will usually suffice.

Test the new lock

To test the new lock without screws, open the door and Cut the Key into the lock. Turn the key to make sure the tumblers move correctly and that your new lockset functions properly. Once you have completed this step, remove and re-insert your key multiple times to ensure that there is no sticking or jamming of any kind. Finally, turn the exterior knob or lever to make sure it operates smoothly. If everything works correctly, congratulate yourself – you have successfully changed a door lock without screws!

Finishing Up

Now that you have the new lock in place, it’s time to finish up. Starting the door knob, attach the latch assembly, the face plate screws, and the strike plate. Make sure the latch slides freely in and out of the latch assembly. Once everything is in place, secure the door with the new lock using the screws provided. Now you can open and close the door lock without any issue.

Reattach the door handle

To finish up, you must reattach the door handle. Begin by wrench-tightening the screws that were temporarily removed at the start of the project. After they are tightened, begin reattaching the door handle to its correct configuration. First, slide on any escutcheon plates that protect your lock and then attach any necessary components (e.g., placement guide or faceplate). Finally, attach both screws to the interior side of your door handle, making sure to practice caution when twisting and maneuvering your tools, as too much force might damage the frame and inner mechanisms of your lock. Insert a key into each side of your lock and turn it back and forth gently to check if it has been correctly installed before turning it completely back in its frame.

Test the new lock again

Now that you have installed the new lock, it is time to test it out. First, make sure the lock is in its locked position. Close the door and jiggle the handle to make sure it does not come undone. If it does, you will need to adjust the pins of the lock by rotating them until they hold securely when you attempt to open the door from the outside. Repeat this process until the handle stays firmly in place.

Once you have checked that the lock is secure, try turning the key from inside and outside of your home just to make sure it works properly. Check if all pins are engaging and disengaging correctly with each turn of your key and if necessary adjust or replace any malfunctioning components before you consider your installation complete. Once everything seems correctly adjusted, your new lock should be ready for use!

Replace any screws that were removed

If any screws were removed in the process of replacing the door lock, they should be reinstalled to ensure a secure installation. The screws should first be put through any oval or circular holes in either side of the Replace Door and door frame. Using a screwdriver, drive each screw into its hole until it’s secured firmly against the frame and the door lock mechanism. Depending on the type of screw used, this may require using an electric or manual screwdriver to turn it fully into its hole. The same screws can also be used to fasten strike plates that were removed during the Replace Door process if necessary. To guarantee a secure installation, check that all screws are tight before completing installation and latch testing of your new door lock.
