How to Install a Lock on a Cabinet: Easy Steps
Published Date: Dec 4, 2025
Adding a lock to a cabinet is one of the simplest ways to boost security for your storage, kitchen, or office space — especially for families with children. Whether you’re doing it for safety, privacy, or peace of mind, knowing how to install a lock on a cabinet the right way matters. In this guide, Sure Lock & Key walks you through the key steps, tools you’ll need, and when it might be smart to call a pro.
What You’ll Need for Cabinet Lock Installation
Before getting started, gather the right tools and parts to make the job smoother and safer. Here’s a basic list for a furniture lock installation:
- A cam lock kit (cylinder, cam/latch plate, nut, screws)
- Drill + proper bits (typically 3/4", 13/16", or 21mm for the main hole — always check your specific kit)
- Tape measure or ruler
- Pencil or marker
- Screwdriver
- Safety gear (goggles and gloves)
If you’re unsure what kind of lock best fits your setup — whether you’re aiming for something temporary or more permanent — our guide on how to lock a cabinet door explains the most popular cabinet lock types and what situations they work best in.
Step-by-Step: How to Install a Cabinet Lock
1. Mark the Lock Spot
Hold the lock against the door to see where it fits best. You want it close to the edge so the latch can actually reach the frame. Once positioned, mark the exact center point for drilling with your pencil.
2. Drill the Hole
Use your drill and a matching bit to make the main hole for the lock cylinder. (Check your kit instructions — common sizes are usually around 3/4" or 21mm). Go slow and apply light pressure to avoid cracking or damaging the surface.
3. Insert the Cylinder
Slide the lock body through the hole from the front. Make sure the keyhole is facing outward and standing up straight (vertical) so it looks professional.
4. Secure the Lock
On the inside of the cabinet, thread the washer and nut onto the back of the lock. Tighten it firmly so the lock stays tight against the door and doesn’t wiggle.
5. Attach Cam or Latch
Fasten the rotating arm (the cam) onto the back of the lock using the small screw provided. This is the piece that actually moves to secure the door.
6. Install the Strike Plate (if needed)
If you have a double door cabinet lock with a key, or if the latch needs something to grip onto, you will need to install the strike plate:
- First, close the door and turn the key to the “locked” position to see exactly where the metal arm hits the frame.
- Mark that spot, line up the strike plate, and screw it into place so the lock catches it securely.
7. Test the Lock
Close the cabinet and turn the key. If the mechanism moves smoothly and clicks shut without forcing it, you’re done!
DIY or Professional Help?
When it comes to cabinet lock installation, the process might look easy. But a small mistake — like drilling too deep or misaligning the strike plate — can make the lock unreliable. That’s why it helps to understand the risks of DIY lock installation, even when you’re working with furniture instead of doors.
For more complex setups like childproof cabinet locks or locking antique pieces, it’s often safer (and faster) to call a pro.
Replacing Existing Cabinet Locks
Need to swap out an old or broken cabinet lock? You’re not alone. Many homeowners eventually need to upgrade their setup for better security. If you’re unsure where to begin or what parts to buy, check out our guide on how to replace a file cabinet lock for detailed step-by-step instructions.

Frequently Asked Questions

For double doors, you typically install the lock body on the active door (the one you open first) and the strike plate on the passive door. This ensures that when you turn the key, the latch catches the second door, locking them both together.
How to install a lock on a cabinet with a key?
The process involves drilling a hole for the cylinder, inserting the lock body, and securing it with a nut from the back. Then, attach the cam (the rotating arm). Always check your drill bit size first to ensure a snug fit.
How to install a lock on a kitchen cabinet door?
If you are installing kitchen cabinet locks for child safety, placement is key. Choose a spot that doesn’t interfere with handles. If you want a clean look that doesn’t ruin your cabinetry design, Sure Lock & Key can recommend high-security, low-profile options.

Wood can split easily. Always mark your spot carefully and drill a small “pilot hole” before drilling the large main hole. Go slow and use light pressure to keep the wood from cracking around the lock.
