This article will provide you with a step-by-step guide on how to reprogram a Master lock, as well as some tips for troubleshooting common problems.
While Master locks are generally reliable, they can sometimes experience problems, such as jammed mechanisms or broken keys. If you are experiencing problems with your Master lock, there are a few things you can do to try to troubleshoot the issue. First, check to make sure that the lock is properly lubricated. If the lock is not lubricated, it can cause the mechanism to jam. Second, check to make sure that the key is not bent or damaged. If the key is bent or damaged, it may not be able to properly engage the lock mechanism. Finally, if you are still having problems with your Master lock, you can contact the manufacturer for assistance.
Master locks are a popular choice for home security, but they can also be used for a variety of other purposes, such as securing storage units, toolboxes, and other valuable items. If you are looking for a reliable and durable lock, a Master lock is a great option. However, if you lose the key to your Master lock, it is important to know how to reprogram it so that you can continue to use it. By following the steps outlined in this article, you can easily reprogram your Master lock without the key.
Identify the Keyhole Type
Master locks come in various models, each with its unique keyhole design. The keyhole type determines the method you need to use to reprogram the lock. To identify the keyhole type, follow these steps:
- Standard Keyhole: This is the most common type of keyhole, found on most padlocks and combination locks. It has a single, round hole and requires a traditional key to open.
- Tubular Keyhole: A tubular keyhole is cylindrical in shape and typically requires a tubular key that inserts into the center of the barrel. This type of keyhole is found on some high-security locks.
- Cross-Shaped Keyhole: This keyhole has a cross-shaped opening and requires a key with a corresponding cross-shaped blade. It is commonly found on fire extinguishers and recessed locks.
- Rim Cylinder Keyhole: A rim cylinder keyhole is a circular hole located on the edge of the lock, rather than on the face. It requires a flat, rim cylinder key that inserts from the side.
| Keyhole Type | Description |
|---|---|
| Standard Keyhole | Single, round hole |
| Tubular Keyhole | Cylindrical shape, requiring a tubular key |
| Cross-Shaped Keyhole | Cross-shaped opening, requiring a cross-shaped key |
| Rim Cylinder Keyhole | Circular hole on the edge of the lock, requiring a flat key |
Once you have identified the keyhole type, you can proceed to the next steps of reprogramming your Master lock.
Remove the Lock Cylinder
To remove the lock cylinder, you’ll need to:
Step 1: Insert the key into the lock and turn it to the “unlocked” position.
Step 2: Push in on the lock cylinder from the inside of the door while turning the key to the “locked” position.
Step 3: Pull out the lock cylinder.
Be careful not to lose the small pins that may fall out of the lock cylinder as you pull it out. These pins are essential for reprogramming the lock, so it’s important to keep track of them.
Once you have removed the lock cylinder, you can proceed to the next step of reprogramming the lock.
Step 4: Reassemble the lock
Once you have reprogrammed the lock, you will need to reassemble it. To do this, simply insert the lock cylinder back into the door and turn the key to the “unlocked” position. Then, push in on the lock cylinder from the outside of the door while turning the key to the “locked” position. Finally, insert the screws to secure the lock cylinder in place.

The reset button on a Master Lock is typically located on the bottom of the lock towards the shackle end, within a small recess. To locate it, turn the lock upside down and look for a small, recessed hole or indentation. You may need to use a flashlight to clearly see the reset button if the lighting is poor.

- Insert the shackle back into the lock body and secure it with the key.
