Are you looking for ways to open your key lock box without the code? Maybe you lost the code or forgot it, or perhaps the lock is not functioning properly.
Forgetting the code to your key lock box can be frustrating and inconvenient, especially when you urgently need access to its contents. Whether you’ve misplaced the code or the locking mechanism has malfunctioned, there are various methods you can attempt to open the lock box without causing damage.

This guide will take you through several techniques on how to open key lock box without code, from using simple tools to more advanced methods, to unlock your key lock box safely and efficiently. Before proceeding, it’s vital to ensure that you are the rightful owner of the lockbox, as unauthorized attempts to open a lock box are illegal and unethical.
What Will You Need?
To successfully open a key lock box without the code, you will need:
- A screwdriver or small drill
- Pliers or wire cutters
- A paperclip
- A hammer (optional)
- WD-40 lubricant spray (optional)
Once you have gathered all the necessary tools, you can begin attempting to open the lock box using one or more of the following methods.
10 Easy Steps on How to Open Key Lock Box Without Code
Step 1: Inspect the Lock Box
Before attempting to open the key lock box, carefully inspect it to understand its design and mechanism. Look for any noticeable screws, hinges, or weak points that can be exploited. This initial assessment will help you determine the best approach and the most appropriate tools to use for the task.
Step 2: Apply Lubricant
Spray a small amount of WD-40 lubricant into the keyhole and any moving parts of the lockbox. This can help loosen any rust, dirt, or debris that might be causing the lock to jam. Allow the lubricant to sit for a few minutes to ensure it penetrates thoroughly, making it easier to manipulate the lock’s mechanism.
Step 3: Try Using a Paperclip
Straighten a paperclip and insert it into the keyhole. Carefully maneuver it around, applying gentle pressure to feel for any internal components. Your goal is to mimic the function of the original key by moving the internal parts until the lock is released. This method requires patience and a delicate touch, as too much force can damage the internal mechanism.
Step 4: Use a Screwdriver or Drill
If the paperclip method fails, try using a small screwdriver or drill. Insert the screwdriver into the keyhole and turn it gently. If necessary, use the drill on a low setting to avoid damaging the lockbox. The objective is to manipulate or dislodge the internal locking pins. Use caution and do not apply excessive force to prevent breaking the lock box.

Step 5: Apply Pliers or Wire Cutters
For more robust lock boxes, you may need to use pliers or wire cutters. Grip any exposed parts of the lock, such as the shackle or keyhole, and apply steady pressure to twist or break them. This method can be effective for cheaper or older lock boxes, but it could also cause visible damage.
Step 6: Tap with a Hammer
As a last resort, you can use a hammer to tap the lock lightly. This method is more appropriate for situations where the lock has rusted and the mechanism is stuck. Lightly tap around the keyhole and hinges to help dislodge any internal components that may be jammed. Be careful not to hit too hard as this could damage the lock box and its contents.
Step 7: Use a Lock Pick Set
If you have experience with lock picking, using a lock pick set can be a precise way to manipulate the internal mechanisms of the lock. Insert the tension wrench into the keyhole and apply slight pressure. Next, use the pick to lift the pins one by one. Listen and feel for a slight click as each pin sets into place. Once all the pins are set, the lock should turn and open. This method requires skill and practice, so it may not be suitable for beginners.

Step 8: Attempt a Bypass Technique
Some lock boxes have weak points that can be bypassed altogether. Check the lock box for a gap around the shackle or hinges where you might be able to insert a thin piece of metal, such as a shim or feeler gauge. Slide the tool into the gap and try to move it around to disengage the lock without directly manipulating the internal mechanism. This method relies on finding a vulnerability in the lock box’s construction.
Step 9: Consult the Manufacturer
If non-destructive methods are unsuccessful, consider reaching out to the lock box’s manufacturer for assistance. They might have a master key or override code for situations like forgotten combinations. Be prepared to provide proof of ownership, such as a purchase receipt or registration details, to obtain their help.
Step 10: Professional Locksmith Assistance
If all else fails, calling a professional locksmith is the most reliable and safe option. A trained locksmith will have the tools and expertise to open the lockbox without causing damage. This may come at a cost, but it ensures that your lock box and its contents remain intact.
By following these steps, you can improve your chances of opening a key lock box without the code while minimizing potential damage. Always prioritize legally and ethically appropriate methods, especially when dealing with secured property.
5 Additional Tips and Tricks
- Use a Shim Tool: A shim is a thin piece of metal or plastic that can be inserted into the gap between the shackle and the body of the lockbox. Gently wiggle and slide the shim to disengage the locking mechanism.
- Try a Lock Bumping Key: Lock bumping involves using a specially designed key to “bump” the pins within the lock into place. Ensure you know how to properly use a bump key to avoid damaging the lockbox.
- Apply Torque with a Screwdriver: Insert a flathead screwdriver into the keyhole and apply slight torque. While maintaining pressure, attempt to manipulate the locking pins with a paperclip or similar tool.
- Freeze the Lock: Spray a commercial freezing spray directly into the lock mechanism. This can make the metal brittle. After freezing, gently tap the lock with a hammer to potentially break the internal components.
- Seek Professional Help: Call a professional locksmith if all else fails. They have the specialized tools and expertise to open the lockbox without damaging it.

With these additional tips and tricks, you should be able to successfully open a lock box in no time. However, always exercise caution and use these techniques responsibly.
5 Things You Should Avoid
- Using Excessive Force: Applying too much force can cause irreparable damage not just to the lockbox, but also to the keys or tools you’re using. This can make it even more difficult to open the lock and could also pose safety risks.
- Drilling into the Lock: Drilling should be a last resort, as it can permanently ruin the lockbox. This technique can also generate metal shards, posing a physical danger to yourself.
- Picking the Lock Aimlessly: Without the proper knowledge and tools, attempting to pick the lock can damage its internal components. To avoid harm, it’s important to use the correct techniques and tools designed for lock picking.
- Ignoring Manufacturer Instructions: Some lock boxes have specific mechanisms designed to thwart tampering. Ignoring the manufacturer’s instructions and attempting random methods could trigger these security features and make it harder to open.
- Using Unauthorized Methods: Engaging in or suggesting illicit methods for opening lock boxes can have legal repercussions. Always ensure that you are trying to open a lock box that you own or have explicit permission to access. Using unauthorized methods not only breaches legal boundaries but also ethical ones.
By avoiding these techniques, you can prevent potential damage and ensure the safety of yourself and others. Remember to always have permission before attempting to open a lock box and use caution when trying any of the methods mentioned above.
How to Reset Your Lock Box Combination
If you have forgotten the combination in your lock box, don’t panic. Most lock boxes come with a reset function that allows you to change the combination. Here’s how:
- Open the Lockbox: Use your current combination or use one of the methods mentioned above to open the lockbox.
- Locate the Reset Button: This is usually a small button located on the inside of the lockbox or on the back panel.
- Press and Hold the Reset Button: Use a paperclip or similar tool to press and hold down the reset button for about 5 seconds.
- Set Your New Combination: After releasing the reset button, use the number dials to set your new desired combination.
- Test the New Combination: Close the lock box and try opening it with your new combination to ensure that it works.

Remember to keep your new combination in a safe place, and never share it with anyone unless necessary. Additionally, make sure to remember or write down the new combination so you don’t have to go through this process again.
Conclusion
How to open key lock box without code can be challenging but manageable with the right tools and techniques. It’s crucial to approach the task methodically and patiently to avoid damaging the lock box or compromising its security features. Utilizing tools like shim tools or bump keys, applying torque with a screwdriver, and employing freezing sprays are practical methods that can help you gain access.
However, it’s equally important to avoid using excessive force, drilling, aimless lock picking, and disregarding manufacturer instructions, as these can lead to irreversible damage or safety hazards. Always ensure you have the legal right to access the lock box and, if in doubt, seeking professional assistance is a wise option.
By following these guidelines, you can effectively and safely open a lock box without the code.
