How to Reprogram a Sentry Safe with or without the Factory Code

Sentry Safes are great for storing all your valuable personal items and protecting them against water and fire. But if you’ve forgotten your combination or accidentally revealed it to someone, how do you reset it? Luckily, resetting your Sentry Safe’s combination is easy—all you need is your safe’s factory code. Don't have it? We'll cover what to do in that case too. Keep reading to learn how to find your safe’s factory code and reset the combination on popular models like the fire, security, depository, and pistol safes.

Things You Should Know

Look for your safe’s factory code in your owner’s manual. It is either listed on the back of the last page or in the programming instructions.
If you don't have a physical copy, find your safe’s owner’s manual online at Sentry Safe’s website.
If you don’t have your combination or factory code, get a replacement by verifying your ownership of the safe and paying a fee on Sentry Safe’s lost combo page.

1
Check your safe’s owner’s manual. Most Sentry Safes provide the factory code, which is the code you enter to start the combination reset process, inside the owner’s manual. This code is usually printed on the back of the manual or listed in the instructions about programming your user code.^{[1]

Research source}
- Some Sentry Safes have default codes that open the safe and reset the combination. All Security Safes come with the factory code 1-7-5-0-0-# while all Pistol Safes have the default code 1-2-3-4-1.
- If you have a safe with a default factory code, reset it as soon as possible. If you keep the combination as the factory code, anyone can look up the code and open your safe.
- Other safes, like the Fire Safe, come with factory codes that are unique to each safe. This code can’t be changed or deleted and always opens your safe.

Look up your owner’s manual online if you don’t have a physical copy. Go to Sentry Safe’s website and enter in your safe’s model or serial number. This information is usually printed on a white sticker that’s stuck to the outside of your safe.^{[2]

- Or, use Sentry Safe’s model and serial number lookup tool to find exactly where the sticker is and how to read it.

Scan the barcode inside the door of your safe if it has one. Open your safe and look for 3 vertical notches along the left side of the back of the door. Then, insert and pry a flat-head screwdriver into each notch to peel the plastic panel from the back of the door. Towards the top, right-hand corner of the door, look for a white barcode sticker. Simply scan it with your phone using a QR or barcode scanning app to receive the factory code.^{[3]

- Depending on your safe model, the panel covering the back of the door might be secured by screws.
- If you can’t scan the barcode because it’s covered by gears or other locking mechanisms, simply peel off the sticker.

Whenever you change your Sentry Safe’s combination, or user code, open up the door. This prevents you from getting locked out of your safe before you reset the code. So, enter the 5-digit factory code listed on the back of your user manual and open the safe.^{[4]

Press “P” on the keypad and enter the factory code. With the safe door open, push the “P” button on the safe’s keypad. On some safes, the “P” key might be labeled “PROG.” Then, enter in the safe’s 5-digit factory code again.^{[5]

Research source}
- On Fire Safes, creating a user code doesn’t delete the factory code. The factory code stays the same and you can use it to open your safe if you forget your user code.
3
Put in your user code when the “Proceed” light flashes green. After you punch in the factory code, you have 5 seconds to enter a new, 5-digit user code. While the “Proceed” light is green, put in your combination. The “Proceed” light will flash again to indicate your user code is set.^{[6]

- If you don’t enter your new user code in 5 seconds, simply start the process again.
- Test your user code to make sure it unlocks your safe while the door is still open.

1
Enter the safe’s factory code to open the door. Use the safe’s keypad to enter the factory code 1-2-3-4-1. Opening the door when you reprogram the combination ensures that you don’t get locked out of your safe while setting the new code.^{[14]
