How to Open a Stack on Safe Without a Key?


Before opening a stack-on safe without a key, taking some precautions is vital to ensure your safety and legality.

Make sure you have the right to open the safe.

Firstly, make sure you have the right to open the safe. If the safe belongs to someone else, you should seek their permission before opening it.

Be aware of any danger or risk.

Secondly, be aware of potential dangers or risks in opening the safe. Depending on the contents of the safe, there may be hazardous materials or sensitive information inside. Additionally, if the safe is large or heavy, it could pose a physical risk during the opening process.

Obtain the necessary tools.

Thirdly, obtain the necessary tools for opening the safe, such as a drill, drill bits, screwdriver, hammer, prybar, and safe lubricant. The right tools will make the process easier and more efficient.

Wear the appropriate protective equipment.

Lastly, wear the appropriate protective equipment to keep yourself safe during the opening process. This may include gloves, goggles, and ear protection. By taking these precautions, you can ensure a safe and successful opening of your stack-on safe.

  1. Gather the materials needed:
  • Drill
  • Drill bits
  • Screwdriver
  • Hammer
  • Prybar
  • Safe lubricant
  1. Ensure you have all these items within reach before beginning the process.
  2. Next, identify the type of lock on your safe. This will guide you in determining the best approach for opening it.
  3. Choose a suitable location to open the safe. Ensure it’s a secure area with enough space to maneuver around the safe.
  4. Check the manual that came with the safe if you have it. This may provide helpful information on how to open the safe without a key or offer alternative solutions.
  5. Lastly, turn off any alarms or notifications triggered by the opening process. This will prevent any unwanted attention and ensure a smooth opening process.

By following these preparation steps, you can be ready to open your stack-on safe without a key.


The drilling process is vital in opening a stack-on safe without a key. Follow these steps to drill the lock and gain access to your safe:

  1. Begin by marking the spot where you will drill. Depending on the location, this should be on the top or side of the lock.
  2. Use the drill to create a small starter hole in the marked spot. This will help guide the drill bit and prevent slipping.
  3. Gradually increase the size of the hole with larger drill bits until it’s large enough to fit a screwdriver or prybar.
  4. Once the hole is big enough, the drill destroys the lock mechanism. This may involve drilling through pins or breaking apart the lock cylinder.
  5. Once the lock is destroyed, use a screwdriver or prybar to twist or pry the lock mechanism out of the hole.
  6. Finally, remove any debris from the hole and the safe. This will ensure the opening process doesn’t leave any damage or clutter behind. These drilling steps allow you to open your stack-on safe without a key.
Pry the Safe Open

If drilling does not work or is not an option, you can try to pry open the safe using a prybar. Here are the steps to follow:

  1. Insert the pry bar into the gap created by the destroyed lock mechanism.
  2. Pry open the door by applying pressure to the prybar. Use a back-and-forth motion to create enough force to open the door.
  3. Once the door is open, remove the lock mechanism and any debris inside the safe.

Remember, prying open a safe can be dangerous and can damage the safe. Use caution and seek professional help if you need more confidence to pry open the safe. With these practical steps, you should be able to pry open your stack-on safe without a key if drilling is not an option.


After successfully opening your stack-on safe without a key, it’s essential to follow these final steps to finish the process:

  1. Clean up the area around the safe. Remove any debris or clutter that may have accumulated during the opening process.
  2. If you continue using the safe, replace the lock with a new one. This will ensure the safety and security of your belongings.
  3. Test the lock to ensure it’s functioning correctly. Make sure the combination or key works and that the lock engages appropriately.
  4. Finally, if you have turned off any alarms or notifications, reset them to protect your safe.

By following these finishing steps, you can ensure the safety and security of your belongings and your home.

Alternative Methods for Opening a Stack-On Safe Without a Key
  • Override Key – Some stack-on safes have an override key allowing you to bypass the locking mechanism. Check the manual to see if your safe has this option.
  • Rare Earth Magnets – Using rare earth magnets to open a safe is a less damaging method than drilling. However, this method only works on safes with magnetic locking mechanisms.
  • Lock Scooping – Lock scooping is a technique professional locksmiths use to open a combination lock by manipulating the lock body. This method requires specific tools and expertise.
  • Paper Clip – A paper clip can manipulate the lock mechanism of some combination lock safes. This method is not guaranteed to work and can damage the lock.
  • Bore Scope – A bore scope is a tool that allows you to see inside a safe without opening it. This method helps check the locking mechanism or find a lost key, but it does not provide access to the contents of the safe.

It’s important to note that attempting to open a safe without a backup key should only be done as a last resort and with caution to avoid permanent damage to the locking mechanism or the contents of the safe. If you are still determining the best method or need the necessary tools, contact a professional locksmith who can offer safe and reliable services.
