Are you wondering how to lock a round door lock? Well, you’re in luck! This blog post will teach you everything you need to know about locking a round door lock .

Gather the Supplies

Locking your round door lock is a relatively simple process that can be done in a matter of minutes. Gather the right supplies before you begin, as the right tools are essential to the job. You’ll need a Phillips head screwdriver, a new lock, a drill and a level. Carefully inspect the lock to make sure all the pieces fit before you begin.

Round door lock

Round door locks are one of the Types of Door that can be surface-mounted with a knob at the center or top. To successfully lock your round door, you will need to have the right supplies and tools. Gather a screwdriver, drill, tape measure, vise grip pliers (optional), a round door lock kit, screws for mounting (included in the kit) and lubricant for tight spots before you begin.


One of the main tools you will need when attempting to lock a round door lock is a screwdriver. It is important to select the correct screwdriver type for the job. A Phillips-head screwdriver or a flat-head screwdriver will work for most locks, but you may need an Allen wrench if the screws are hex-head. Be sure to get a good quality screwdriver that fits snugly into the screws and does not slip or wobble inside them. This will help reduce your chances of stripping or breaking off the screws while attempting to lock the door.

Remove the Existing Lock

The first step to locking a round door lock is to remove the existing lock. Depending on how the existing lock is installed, you may need to use a screwdriver or a wrench to remove it. If necessary, you may need to replace the screws with longer ones, as this will make the installation of the new locking system easier. Once the existing lock is removed, you can move on to the next step.

Unscrew the existing lock

When attempts to unlock a round door lock fail, it may be time to remove the existing lock. The process for removing a lock varies depending on the exact type of door lock and various factors related to the condition of its components. Once you have established an appropriate game plan, it is possible to uninstall an existing round door lock in a few simple steps.

The first step is to unscrew the existing lock. It is important to observe which way the screws are facing when they are removed since this will help immensely during the replacement process. If you cannot immediately access these screws due to excess rust or corrosion buildup, you should use a lubricant or rust remover on them to make them easier to turn. Once all of the screws have been successfully loosened, gently remove any pieces that need unscrewing before you can free up any bolted sections of the current installation. When removing components such as pins and bolts, you should also take note of how they were placed and their orientation as this information will be crucial when installing your new identical set of parts on your main door components.

Remove the existing lock

Before installing a new round door lock, the existing one must first be removed. This is a simple task, but it’s important to take care when doing so as to not damage the door in the process.

In order to remove an existing round door lock, gather the following materials: screwdriver (flat head and Phillips head) and pliers. Begin by locating all screws that hold the lock together, which can be found around the edge of the lock body. Using a screwdriver, remove all screws from both sides of the lock body and pull off any trim caps from around both edges of the interior side of the door.

Next, locate and remove any pins or small parts located inside of each side of the door frame with a pair of pliers. Then grab onto either end of the rim cylinder and rotate it away from each side until it pops off from its housings on both sides. Once you have done this, you can easily pull out your old lock body entirely followed by its cylinders as well as other components such as strike plates or latch bolts. Be sure to store all components safely while they are out of use so they can be reused later on if needed.

Install the New Lock

Installing a new round door lock can be easy. There are a few simple steps to follow when it comes to installing the new lock. For starters, you have to make sure the door is properly prepared and the correct tools are available. Then, you need to install the latch and then attach the faceplates. Once that is completed, you can move onto the next step, which is to attach the deadbolt.

Insert the new lock

Once you have chosen a new lock, the next step is to insert the new lock into the existing door. To do this, first remove the screws that secure the old lock to the door. Carefully pull out the old lock and set it aside.

Now place the new lock on your door and make sure that it fits properly. If there are any gaps or other issues, mark them with a pencil so you can adjust accordingly. Use a ruler to ensure that everything is aligned properly before moving forward.

Carefully slide in the new latch assembly and fix it into place using your screws or nails. Make sure they are pressed deep enough into the wood to ensure that everything is securely attached.

If your new round door knob comes with two separate components to install-the cylinder and trim plate-it can be a good idea to attach both components before fixing them in place with screws or nails. Once all components are securely installed, give everything one final check for any loose fasteners or parts, then you’re all set!

Secure the new lock with screws

Once you have chosen a new round door lock, then it is important to securely install the door lock in your door. To properly install a round door lock, you should begin by latching the latch into the locked position. Next you should locate the jamb bracket – this is normally located on the top of the latch plate. Then insert two screws through the two holes in the jamb bracket. Secure these screws into place using a screwdriver until they are tight. If necessary, use pliers to ensure they are not too loose and that they are snugly fitted into place. Finally, close and test your new round door lock.

Test the Lock

Testing a round door lock is an important part of ensuring that the lock is functioning correctly and securely. Knowing how to properly test the lock will help to ensure that you can use the lock correctly and securely. Let’s look at how to test the lock so that you can rest assured that the lock is secure and functioning properly.

Test the new lock

Once the new lock has been installed, it’s important to check the fit and performance by testing the lock. Testing the lock will ensure that it is secure and functioning properly. To test your new round door lock:

1. Close the door and turn the key in each direction several times. This can help make sure that all of the inner workings of the lock are seated properly.
2. Next, check whether or not all of the components move easily and without catching on anything when you turn the key left or right. If any parts seem to have rough edges or are hard to move, they may need to be adjusted accordingly.
3. Check how firmly and securely the door locks into place with its deadbolt when you’ve turned the key in each direction several times. This will tell you if there are any gaps in between where gaps might occur when locked, which could compromise security of your home or business premises
4. Lastly, test any other associated features like levers or knobs for smooth operation and precise positioning in both directions – up/down as well as left/right motions should be tested for proper installation and optimal functioning of round door lockset

Adjust the lock if necessary

When the lock is in place, it’s time to test it. Before turning the key, test the latch with your finger: If it feels too tight or too loose, adjust the lock. To adjust a round door lock, you’ll need an allen wrench.

To tighten a round door lock turn the allen wrench counterclockwise and to loosen a round door lock turn the allen wrench clockwise. After each adjustment be sure to try inserting and turning the key before making any further adjustments. Make slight adjustments at a time until you get just the right amount of tension with the latch when installing or adjusting any type of mortise lockset.
When you are finished adjusting, double check that your key turns smoothly in both directions without sticking and make sure there is no play between door and frame. Once everything feels right, you are done!

Finish Up

After you have installed the round door lock, you need to do a few final tasks in order to ensure that it is properly secured. This includes inserting screws, latching the door, and testing the lock. It is important to follow the instructions provided by the manufacturer in order to ensure that the round door lock is properly secured. Let’s take a look at the final steps of locking a round door lock.

Replace the door knob

Once the hardware is uncovered, replacing the door knob or lever is a relatively simple process. Carefully loosen the screws that secure the knob to the door and remove it, then remove any connecting rods attached to it. To attach the new door knob or lever, fit it into place according to the manufacturer’s instructions and secure with appropriate screws. Connect all necessary rods and linkages according to instructions, then reattach any decorative faceplates. Situate the key in its position and make sure that both sides of lock are free of obstructions. Turn freely to ensure all components are aligned properly before you put everything back together. Test your work by turning your new key and make sure that it turns easily before you replace all screws and cover caps.

Clean up any debris

Once you have the screws removed from the lock, take some time to clean up any debris inside the door. This may include old pieces of hay, dust, or dirt that has accumulated over time. Use a vacuum and brush attachment to remove any build-up or use compressed air or a soft brush to reach smaller areas. Doing so will help ensure a smoother operation of your new lock when it’s installed.
