How to Remove a Cam Lock: Complete Step-by-Step Guide
Published Date: Oct 10, 2025
Cam lock removal can be simple — if the lock is already open and the hardware is intact. When it’s stuck, damaged, or the key is missing, the process becomes more technical and may require extra care. In this article, Sure Lock & Key explains how to remove a cam lock safely in both standard and more complicated situations. We’ll walk through the tools you may need and practical tips to keep the process clean, safe, and successful — plus what to do if you’re reinstalling or replacing the lock.
What to Know Before Removing a Cam Lock
A successful cam lock removal starts with understanding what you’re working on and having the right tools nearby. A cam lock includes a cylindrical body, a flat metal arm (the cam), and a nut or clip that holds everything in place. Turning the key rotates the cam to either block the cabinet frame or move out of the way. Having a basic grasp of how a cam lock works makes the removal process much more intuitive.
You’ll also want to gather the right tools ahead of time. For a standard removal, prepare a flathead screwdriver, a Phillips screwdriver, and a pair of pliers. If the lock is stuck or you don’t have the key, you may also need a drill with multiple bit sizes. And if drilling is required, safety glasses are strongly recommended to protect your eyes.
Step-by-Step: How to Remove a Cam Lock Safely
The removal process varies depending on whether you have the key. Below are the steps for both scenarios.
If You Have the Key
- Unlock the Cam: Insert the key and turn it to the unlocked position. This moves the cam arm out of the way.
- Remove the Screw and Cam: Open the drawer or door to access the back of the lock. The cam arm is usually held in place by a small screw. Not sure how to remove a cam lock screw? Just grab a flathead or Phillips screwdriver and loosen it until the cam arm comes free.
- Unfasten the Nut: Use pliers to grip the large nut holding the lock body to the door and turn it counter-clockwise to remove it.
- Extract the Lock: The lock body will now be loose, and you can pull it out from the front.
If You Don’t Have the Key
Without the key, the cam is locked in place. The most direct method is to drill out the lock, which will destroy it.
- Create a Guide Point: Use a center punch to make a small indent in the middle of the keyhole. This prevents the drill bit from slipping.
- Drill the Lock: If you’re wondering how to drill out a cam lock, start with a small drill bit and drill through the keyhole to break up the internal pins.
- Widen the Hole: Switch to a larger drill bit, roughly the diameter of the keyhole, and drill again to destroy the mechanism.
- Turn the Lock: You should now be able to insert a flathead screwdriver into the lock and turn it as you would with a key.
What Comes After Cam Lock Removal: Replacing or Upgrading
After removing the cam lock, you’ll want to decide whether to reinstall the same type or upgrade to a more secure option. If the lock was damaged or unreliable, replacing it with a better option can prevent future issues.
