How to Remove a Lock from a Door Knob: Step-by-Step Instructions

If you want to remove a lock from a doorknob, here’s a simple way. If you’re working with a door knob with a lock that uses a key, you can often take out just the lock cylinder without needing to remove the entire door knob assembly from the door. It’s an easy task you can handle yourself with a few simple steps.

Step 1: Insert the Correct Key

Insert the key that operates the specific door knob lock you’re working on, pushing it fully into the keyhole.

Step 2: Turn the Key to the “Service” Position

Gently turn the key. On most brands, you’ll turn it about 1/4 to 1/2 of a turn, usually in the direction you would turn it to unlock the door. The goal is to align the internal pins to release the cylinder. Hold it precisely in this spot.

Step 3: Locate the Release Mechanism

While holding the key in the turned position from Step 2, locate the small release pin, button, or tiny hole near the base of the doorknob. This is the release mechanism for the lock cylinder.

Step 4: Depress the Release

Use a small, pointed tool — a paperclip, thin punch, or a special tool that may have originally come with your door knob lock — to press gently but firmly into the release hole or onto the pin. You should feel it depress slightly.

Step 5: Slide the Cylinder Out

Now, this is where it all comes together: while you are still keeping the release mechanism depressed and the key is held in the correct turned position, gently pull the key straight outwards. The lock cylinder should slide out of the door knob handle.

Step 6: Remove the Key

Once the cylinder is completely out, you can remove the key from it. With these simple steps, you’ve successfully managed to remove the lock from the door knob.

Removing a door knob lock might seem intimidating at first, but it’s achievable with a little patience and the right guidance. After removing the old lock, take a moment to clean the door surface and check the hole size if you’re installing a new one.
