10 Methods How to Reset Puroma Lock Box
1. Locate the Reset Lever Inside the Box
The most straightforward method to reset a Puroma lock box involves accessing the reset lever located inside the box. First, you must unlock the box using the existing combination. Once open, look for a small lever or button, usually located on the interior side or near the dials.
Slide or press the lever to the reset position (often marked with “RESET”). After positioning the lever, change the combination by rotating the dials to your desired numbers. Once the new code is set, return the lever to its original position. Test the new combination several times before closing the box to ensure accuracy.
2. Use the Default Factory Code
If the lock box has never been reset or has recently been purchased, it may still have the factory-set code. Typically, Puroma lock boxes are preset to a default code like 0000 or 1234. To reset the code, open the box using this default number, locate the reset lever inside, and follow the standard resetting procedure.
If the box does not open with these default numbers, the code has likely been changed, and you may need to attempt other methods or contact Puroma for assistance.
3. Resetting When You Forget the Code
Forgetting the code can be a frustrating situation, but it doesn’t mean your lock box is permanently unusable. Start by trying common number combinations or variations of familiar codes. If that doesn’t work, you may need to use a combination recovery technique.
One option is to apply slight pressure to the open lever while gently rotating each dial. Listen for a subtle click or feel for a slight give, which may indicate the correct number. Once all dials are aligned correctly, the box should open, allowing you to proceed with the reset process as described previously.
4. Refer to the User Manual
If you are unsure of the resetting process, consulting the Puroma user manual can be invaluable. The manual typically contains detailed instructions specific to your lock box model. If you no longer have the manual, check the official Puroma website for a digital copy.

Manuals often include troubleshooting tips and may provide unique instructions based on your lock box model. Following the manual’s step-by-step guidance can save you time and prevent unnecessary frustration.
5. Contact Puroma Customer Support
If the standard reset methods don’t work, it may be time to reach out to Puroma customer support. Prepare to provide details such as the lock box model number and proof of purchase. The support team can guide you through advanced resetting techniques or suggest professional services if necessary.
They might also inform you if your model requires a specific tool or key for resetting. Customer support is often the best option when dealing with a stubborn or malfunctioning lock box.
6. Try a Sequential Code Reset
Sometimes, the most methodical way to reset a forgotten combination is to attempt a sequential code reset. Start by setting the dials to 0000 and try to open the box. If it doesn’t open, move on to 0001, then 0002, and continue through all possible combinations up to 9999.
This method can be time-consuming, but it is effective if you are determined to recover the combination without forcing the lock. Once opened, immediately reset the code to something memorable and unique.
7. Inspect the Box for Physical Clues
In some cases, wear and tear on the dials can provide clues to the previous combination. Check the dials for scratches, dents, or faded numbers that might indicate frequent use. Sometimes, users tend to rotate specific numbers more often, leaving subtle marks.
Aligning these worn numbers and gently testing the lock may help you find the correct combination. Once open, perform the standard reset procedure to set a new code that is both secure and easy to remember.
8. Use a Combination Recovery Tool
Locksmiths often use combination recovery tools that help detect slight shifts in dial resistance when the correct number is aligned. You can purchase similar tools online or at a hardware store. To use the tool, insert it next to each dial and gently rotate while feeling for changes in tension.
This technique works by exploiting minute differences in how the dials sit when correctly positioned. After recovering the correct combination, follow the typical reset process to change the code.
9. Resetting a Stuck or Jammed Lock Box
If your lock box seems stuck or unresponsive, it might be jammed due to debris or misaligned dials. Try applying a gentle tap on each side to dislodge any obstructions. Lubricating the dials with a small amount of silicone spray can also help ease movement.
Once the dials move freely, try the last known combination again. If successful, open the box and proceed with the reset process. Regular maintenance, such as cleaning the dials and applying lubricant, can prevent this issue from occurring in the future.

10. Seek Professional Locksmith Assistance
If none of the methods above work, or if the lock box appears to be damaged, consider hiring a professional locksmith. Locksmiths have specialized tools and experience to open lock boxes without causing damage. They can also reset the combination for you and ensure that the lock remains functional.
While this may involve a cost, it is often a better alternative to forcing the box open and rendering it useless. Always choose a reputable locksmith to avoid potential security issues.
Maintenance and Upkeep
Proper maintenance of your lock box is essential to ensure its longevity and functionality. Start by regularly cleaning the exterior and interior of the box to remove dirt, dust, and debris that can accumulate and affect its operation. Lubricate the locking mechanism using a silicone-based lubricant to keep it operating smoothly and prevent it from seizing.
Check the combination or key periodically to ensure it is working correctly, and replace any worn or damaged components promptly. If your lock box is exposed to outdoor elements, consider placing it in a sheltered location or using a weather-resistant model to protect it from rust and corrosion.
Regular upkeep not only extends the lifespan of your lock box but also ensures the security of the contents it protects.
Safety Considerations
When using a lock box, it is important to prioritize safety to safeguard both the contents and individuals accessing it. Always select a discreet location for your lock box to minimize visibility and reduce the risk of tampering. Share the combination or key only with trusted individuals and avoid leaving it in easily accessible areas.
Regularly update the lock combination to further enhance security, particularly if there are changes in who requires access. For lock boxes holding valuable or sensitive items, consider integrating them with additional security measures such as cameras or alarms. These precautions ensure that your lock box remains a reliable and safe storage solution.

Conclusion
Resetting a Puroma lock box can be a straightforward task if you remember the original combination, but it becomes challenging when the code is forgotten or the lock is jammed. The methods outlined above provide various approaches depending on your situation, from using the default code and inspecting for physical clues to contacting customer support or seeking professional help.
