Installation Steps
⚠️ Heads up: Depending on the age and location of your lock, you may find insects (ants, spiders) inside when you open it. Not unusual — don’t be surprised.
1. Review the damage examples above to confirm your lock has enough structure remaining to accept a replacement knob. Add a Body Cover to your order if there is damage to the lock body below the knob.
2. Locate the Torx T10 security screw on the front face of the lock body. Unscrew it completely. Once removed, the front cover will come off from the bottom.
3. Pull the lock unit (white plastic and metal lock mechanism) out of the body. With the lock removed, you will see the fork and the shaft that the knob connects to. Use needle-nose pliers to grab the side of the fork and pull it firmly toward you to separate it from the shaft.
4. Finish separating the fork by hand. Push the shaft upward to remove what remains of your existing knob.
5. Insert the replacement knob with the arrow (and sticker) facing the front of the lock.
6. Pull the fork piece up and out, guide it over the T-shaped shaft, and gently push down until it snaps into place.
7. Verify that the knob moves and operates correctly — pull up to confirm the latch releases.
8. Reinstall the lock unit by lining the lock spindle up with the hole toward the back of the body.
9. Screw the front cover back on with the Torx T10 screw.
10. (Optional) If you purchased a body cover, unscrew the aluminum knob cover and install your body cover.
Done!
