How to Open a Lock Box Without a Key: Mastering Access in 2023

Unlocking a lock box without a key can be a lifesaver in certain situations, but it’s crucial to approach it legally and responsibly. In this guide, we’ll explore seven methods to open a lock box without a key or code. Remember, these methods are intended for legal use, and unauthorized attempts can lead to legal consequences.


Before delving into the techniques, a crucial reminder: only attempt to open a lock box if you are the owner or have explicit permission. Unauthorized attempts are illegal and can result in serious consequences. Continue reading only if you’re seeking legal ways to regain access.

1. Bypassing

Bypassing involves manipulating a lock’s actuator directly, often by reaching through the keyway. Specific techniques may vary, but manipulating the actuator, using tools to turn it, or employing factory reset bypasses are common strategies. Always check your lock box’s documentation for potential bypass methods.

Key Takeaways:

  • Research documented bypass methods for your specific lock box.
  • Utilize tools to manipulate the lock actuator through the keyway.
  • Check the manual for factory reset codes.
  • Some electronic locks may have reset switches accessible through gaps.

2. Shimming

For lock boxes secured with padlocks, shimming can be effective. Cheap padlocks are often vulnerable to shimming, a process of inserting thin pieces of metal between the shackle and lock body. Improvised shims made from an aluminum can can work effectively.

Key Takeaways:

  • Padlock-secured lock boxes may be vulnerable to shimming.
  • Craft improvised shims from an aluminum can.
  • Note that some padlocks are protected against shimming.

3. Picking

Lock picking, specifically raking, can be a novice-friendly way to open a lock box without a key. While professional tools make the process easier, it’s possible to try with improvised tools. Experiment with tension and practice patience.

Key Takeaways:

  • Novices can attempt to pick lock box locks.
  • Improvised lock picks may be more challenging to use successfully.
  • Remember that broken locks cannot be picked open.

4. Decoding

Decoding is applicable to wheel combination locks found in some lock boxes. By manipulating each wheel one number at a time, you can identify the correct combination through the play of the wheels.

Key Takeaways:

  • Wheel combination locks are susceptible to decoding.
  • This process is done by feel and requires no tools.
  • Complex forms of lockbox decoding exist.

5. Drilling

Drilling out the lock cylinder can be a quick and destructive method, but it allows for the lock’s replacement without replacing the entire box. Adequate preparation, including lubrication and proper drill bit selection, is essential.

Key Takeaways:

  • Drilling requires a lock box with a removable lock cylinder.
  • Prep your lock with lubrication before drilling.
  • Consider other methods if the lock is irremovable.

6. Prying

Prying is a straightforward method that involves wedging a tool, such as a crowbar, between the door and frame of the lock box. While effective, it often results in damage to the box.

Key Takeaways:

  • Prying can damage or destroy the lock box.
  • Choose a tool that fits the lock box’s crevice and provides sufficient leverage.
  • Stabilize the lock box to prevent movement during prying.

7. Cutting

Cutting the locking mechanism is a destructive but effective method. An angle grinder is an ideal tool for this purpose, offering versatility and power. However, cutting may render the lock box unusable.

Key Takeaways:

  • Cutting is irreparably destructive to the lock box.
  • An angle grinder is recommended for cutting open a lock box.

Closing Words

Opening a lock box without a key involves understanding your tools and the type of locking mechanism. Whether you opt for non-destructive methods like bypassing, shimming, picking, and decoding, or resort to destructive techniques such as drilling, prying, or cutting, it’s crucial to approach each method with caution and legality in mind.
