Preparing the Master Lock Lockbox
Before you can open a Master Lock lockbox, there are a few steps you need to take to ensure a smooth and successful process:
**Inspect the lockbox:**
– Check the lockbox for any visible damage, such as scratches, dents, or rust. If you notice any damage, it’s recommended to contact Master Lock or a professional locksmith for assistance.
**Gather the necessary tools:** The following tools may be required for opening the lockbox:
– Key (if available)
– Combination reset tool (if available)
– Screwdriver
– Hammer (optional)
– Flashlight (optional)
**Position the lockbox:** Place the lockbox on a stable and flat surface. If the surface is unsteady, the lockbox may move or shift, making it difficult to open.
**Lubricate the lock:** If you’re having difficulty opening the lock, applying a small amount of lubricant to the keyhole can help. Use a dedicated lock lubricant or graphite powder.
**Test the key:** If you have a key for the lockbox, insert it into the keyhole and gently turn it back and forth. If the key fits and the lockbox opens smoothly, you can proceed to your desired operation.
Selecting the Correct Key or Combination
Unlocking a Master Lock Lockbox requires choosing the appropriate key or combination. For keys, consult the original packaging or reach out to the manufacturer with the lockbox model number. If the lockbox is combination-based, follow the steps outlined below:
1. Locate the Reset Button
Turn the lockbox over to find a small, recessed reset button. Press and hold the button while completing the next steps.
2. Set the Combination
With the reset button depressed, spin the dials to your desired combination. The lockbox will record the sequence upon releasing the reset button.
3. Test the Combination
Release the reset button and check if the latch opens by turning the dials to the new combination. If unsuccessful, repeat steps 1-2, ensuring the dials are accurately set.
4. Memorize or Record the Combination
Once the lockbox is open, write down or memorize the combination for future use. Keep it confidential to prevent unauthorized access.
| Step | Action |
|---|---|
| 1 | Locate reset button |
| 2 | Set combination with button depressed |
| 3 | Test combination |
| 4 | Memorize or record combination |
Inserting the Key or Inputting the Combination
Master Lock lockboxes feature a user-friendly design that allows for both keyed and combination access. To open the lockbox using a key, simply insert the key into the lock and turn it clockwise. If you are using a combination, follow these steps:
| Step | Action |
|---|---|
| 1 | Rotate the dials until the first number in the combination lines up with the index mark. |
| 2 | Turn the dials clockwise, passing the first number twice. |
| 3 | Turn the dials counterclockwise, stopping at the second number in the combination. |
| 4 | Turn the dials clockwise again, passing the second number twice. |
| 5 | Turn the dials counterclockwise, stopping at the third number in the combination. |
| 6 | Pull down on the latch to open the lockbox. |
Opening the Lockbox
To open a Master Lock lockbox, follow these steps:
1. Align the Dial
Turn the dial clockwise three complete turns, stopping at the first number in your combination. Turn the dial counterclockwise one full turn, then stop at the second number. Repeat this process for the third and fourth numbers.
2. Press the Latch Button
Locate the latch button on the bottom of the lockbox. Press and hold it down while pulling up on the shackle. The shackle should open if the combination is correct.
3. Reset the Dial
To reset the dial, turn it clockwise around five full turns. This will scramble the numbers and prevent unauthorized access to the lockbox.
4. Troubleshooting
If you are having trouble opening the lockbox, try the following troubleshooting tips:
| Problem | Solution |
|---|---|
| The shackle does not open when the correct combination is entered. | Ensure that you are pressing and holding the latch button while pulling up on the shackle. The button must be held down for the shackle to open. |

Removing the Contents
Once you’ve opened the lockbox, it’s time to retrieve its contents. Here are the steps:
- Grip the release button: Locate the release button on the back of the lockbox. It usually has an arrow or "open" symbol.
- Press and hold: Press and hold the release button firmly.
- Pull open the door: While holding down the release button, pull open the lockbox door.
- Remove the contents: Carefully remove the items stored inside the lockbox.
- Additional tips:
- Avoid using excessive force: Be gentle when pulling open the door, as forceful actions can damage the mechanism.
- Use a flashlight: If necessary, use a flashlight to illuminate the interior of the lockbox, especially if it’s dark.
- Check for hidden compartments: Some lockboxes may have concealed compartments. Explore the interior thoroughly to ensure you’ve retrieved all the contents.
- Keep the temperature in mind: Extreme temperatures can affect the functionality of the lockbox. Avoid using it in freezing or scorching conditions.

Resetting the Lockbox Combination
The reset process for Master Lock lockboxes involves some additional steps to ensure secure reprogramming. Here’s a detailed breakdown:
1. Open the Lockbox
Before resetting the combination, you’ll need to open the lockbox using the existing code. Ensure the lockbox is in the open position.
2. Find the Reset Button
Inside the lockbox, locate the reset button, usually situated on the back or bottom panel. It’s often a small, recessed button.
3. Press and Hold the Reset Button
With the lockbox open, firmly press and hold down the reset button using a pen or pencil. Keep holding it for the next steps.
4. Enter the Current Combination
While still holding down the reset button, dial in the current combination using the dials. Do not release the reset button yet.

With the reset button still held down and the current combination entered, press the door release button to open the lockbox.
6. Enter the New Combination
This is the complex part. While still holding down the reset button and keeping the door open, proceed to dial in the new combination you want to set. Ensure you remember the new combination.
The reset process is very time-sensitive. If you hesitate or release the reset button at any point before completing step 6, the reset will fail, and you’ll need to start over.
