Luckily, cabinet lock replacement is a straightforward process that you can tackle yourself.

In this comprehensive guide, we will walk you through the entire metal cabinet lock replacement process step-by-step. We will cover how to remove the old lock, select the right replacement lock, install the new lock correctly, and test the new lock to ensure it is working properly. With these instructions, you will have the knowledge needed to swap out an old, broken cabinet lock for a shiny new one with minimal hassle.

Gathering the Necessary Tools and Materials

Before starting the cabinet lock replacement process, you will need to gather a few essential tools and materials. Having these items on hand will make the lock removal and installation much simpler.

Tools Needed

• Phillips screwdriver – This is needed to remove the screws from the old lock and install screws for the new one. A power drill with Phillips bit can also quicken the screwing and unscrewing process.
• Hammer – A light tapping with a hammer may be needed to loosen the old lock from the cabinet door or drawer front if it is stuck.
• Pliers – Standard locking pliers can help grab and turn stuck lock cylinders.
• Ruler or measuring tape – Required to measure the backset and hole spacing of the old lock to find a replacement match.
• Pencil – Used to mark measurements on the new lock.
• Scrap wood – A piece of scrap wood can be used to protect the cabinet door when hammering out the old lock.

Materials Needed

• New cabinet lock – This should match the backset measurement and hole spacing of your old lock.
• Lock installation kit – This typically comes with the new lock and includes screw hole covers and installation screws.

Once you have gathered the necessary tools and materials listed above, you can get started with removing the old cabinet lock.

Removing the Old Damaged Cabinet Lock

The first step in the replacement process is to fully remove the old, damaged lock from the cabinet door or drawer front. Here are the details on how to carefully take out the old lock:

1. Open the cabinet door or drawer that has the lock you need to replace. Then, remove any contents so you have full access.
2. Examine how the lock is installed. Note the screw locations and any special mounting plates or brackets. You will need to reuse the same screw holes later.
3. Use a Phillips screwdriver to remove any screws holding the lock or mounting plate in place. Set the screws aside in a safe spot.
4. Wiggle the cylinder part of the lock back and forth while pulling outward. Apply firm pressure to slide the cylinder and lock body out from the door or drawer.
5. If the cylinder won’t budge, place a piece of scrap wood against the door surface for protection. Then use a hammer to firmly tap the lock body until it breaks free.
6. Remove any remaining lock components or plates still attached to the cabinet door or drawer front. Try pliers if pieces are stuck.
7. Examine the now vacant hole where the lock was mounted. Clean out any debris or old adhesive with a damp rag.

With the hole cleared and ready, it is now time to choose and purchase a suitable replacement lock.

Selecting the Right Replacement Cabinet Lock

Since you removed the damaged cabinet lock, you now have all the necessary measurements to select a proper replacement lock. Follow these tips for picking a compatible new lock:

• Measure the backset length – Use a ruler to measure the distance from the door or drawer edge to the center of the lock hole. This is called the backset length and is typically 2-3/8″ or 2-3/4″.
• Measure screw hole spacing – Measure the distance between the two screw holes that mount the lock. This is usually 28mm.
• Match the replacement – Purchase a new cabinet lock that has the same backset length and screw hole spacing as your measurements. This ensures a seamless fit.
• Consider the locking style – Think about the lock operation on your cabinet. A keyed lock may be best for a drawer. A magnetic or push-to-open lock may suit a cupboard.
• Get matching finishes – For a consistent look, opt for a new lock with a finish that matches your cabinet hardware. Oil-rubbed bronze and brushed nickel are common.

With the proper new lock selected, you can move on to the installation process.

Installing the New Cabinet Lock Properly

Once you have the new replacement lock, it is time to install it properly into the cabinet door or drawer front. Follow these key steps for smooth installation:

1. Place the lock against the door/drawer and align the lock cylinder tailpiece with the crossbore hole. Ensure the screw holes line up with the existing cabinet holes.
2. Use a pencil to lightly mark the shape of the lock on the cabinet surface. This outline will help keep the lock flush as you attach it.
3. Place the provided template (if any) for the lock over your pencil outline. Use a utility knife to carefully cut any extra door/drawer material within the template outline.
4. Insert the lock tailpiece into the crossbore hole. Position the lock body against the door/drawer within your outline.
5. Using a Phillips screwdriver and provided screws, attach the lock body portion first with the screws. Tighten screws firmly but not completely.
6. Next, insert cylinder portion of the lock into the body, aligning their tailpieces. Usually the cylinder will snap into place.
7. Make any needed cylinder adjustments and ensure the lock functions properly. Then tighten all lock screws completely.
8. Press the screw hole covers included with the lock kit over the mounting screw holes for a clean finish.
9. Check that the lock and key work correctly to open/close the cabinet. If needed, tweaks can be made to the cylinder tailpiece alignment.

With the new cabinet lock installed properly, the final step is testing the lock function and performance.

Testing the Newly Installed Cabinet Lock

Before putting your newly lock-replaced cabinet into regular use again, take time to thoroughly test the lock replacement. Here are some ways to validate the success of your cabinet lock installation project:

• Lock and unlock the cabinet multiple times with the key to ensure smooth operation.
• Lock the cabinet then attempt to pull/shake it forcefully to confirm it is secure. Watch for any shifting.
• Open and close any drawers to test that alignment did not shift during the lock swap. Adjust cylinder tailpiece if needed.
• Ensure the keyed portions face outwards properly when cabinet doors/drawers are closed.
• Check that the new lock and cylinder match the finish of other hardware. Blend any color variations with touch up paint.
• Have other household members test operating the newly replaced lock with the key.
• Consider locking the cabinet overnight then checking in the morning that the contents remain secure.

Taking this time to carefully test and inspect your lock replacement work will ensure no issues arise later on. With the steps above completed properly, you can rest assured that your metal cabinet will now have a fully functioning lock once again. Nice work!

Frequently Asked Questions About Replacing Cabinet Locks

1. How do I get an old stubborn cabinet lock off?

• You will need to measure the backset (distance from cabinet edge to lock center) and the spacing between the two screw holes. Match these to the replacement.

1. My replacement cabinet lock screws are too short. What can I do?

• If the provided screws are too short, you can try using the original screws from the old lock. If those are also too short, purchase slightly longer screws that fit the holes.
