Opening a Big Green Safe Delta Force without the combination
A Big Green Safe Delta Force is a compact home safe, usually 14 to 16 inches tall, with a digital keypad or mechanical dial. If you have lost the combination or the safe was left behind by a previous owner, you have three main routes: contact the manufacturer for a reset, call a locksmith, or attempt a reset using the manufacturer's override procedure if one exists for your model.
The fastest option depends on whether you have proof of ownership and whether you know the safe's serial number. The manufacturer can usually reset the lock in one to three business days if you provide a copy of the original receipt or proof of purchase. A locksmith can open it the same day but will charge a service fee, typically $75 to $200 depending on your location and the safe's lock type.
Key Takeaways
- Contact Big Green Safe directly with your proof of ownership and serial number — they can reset the lock without damaging the safe.
- A locksmith can open the safe on the same day but will charge a service fee and may need to drill or manipulate the lock.
- The serial number is usually stamped on the back or bottom of the safe and is required by the manufacturer to process a reset.
- If the safe is bolted to a floor or wall, removing it may require tools or professional help before a locksmith can transport it.
Contacting the manufacturer for a reset
Big Green Safe is the manufacturer of the Delta Force line. You can reach them by phone or through their website to request a lock reset. Have your proof of ownership ready — this can be a receipt, an invoice, a credit card statement showing the purchase, or a photo of the safe with identifying marks. The manufacturer will ask for the safe's serial number, which is stamped on the back panel or the bottom of the unit.
Once Big Green Safe confirms ownership, they will send you instructions for resetting the lock. For digital keypad models, this usually involves entering a master code or a sequence of button presses. For mechanical dial models, the process may require removing the lock assembly, which typically involves unscrewing the interior bolts. The manufacturer can walk you through this over the phone or send written instructions by email.
This route takes longer than a locksmith visit but costs nothing and leaves the safe intact. If you do not have proof of purchase, the manufacturer may still help if you can provide the serial number and answer security questions about the safe's history.
Hiring a locksmith to open the safe
A locksmith can open a Big Green Safe Delta Force without the combination by manipulating the lock or, if necessary, drilling it. Call a locksmith in your area and describe the safe — mention that it is a Big Green Safe Delta Force, the approximate age if you know it, and whether it has a digital keypad or a dial. Ask for a quote before they arrive, as prices vary by region and by the time required to open it.
Most locksmiths can open a Delta Force in 30 minutes to an hour. If the lock can be manipulated without damage, the safe will remain fully functional. If the lock must be drilled, the locksmith can usually install a new lock mechanism afterward, though this adds to the cost. Ask whether the quote includes lock replacement or if that is billed separately.
Bring a photo ID and proof that you own the safe — a receipt, a bill of sale, or a photo of yourself with the safe. Locksmiths are required by law in most states to verify ownership before opening a locked container. If you cannot provide proof, some locksmiths will still help but may charge a higher fee or ask you to sign a liability waiver.
Finding the serial number on your safe
The serial number is a unique identifier stamped into the metal of the safe. On a Big Green Safe Delta Force, it is usually located on the back panel near the bottom, or on the underside of the safe if it is not bolted down. The number is typically five to eight digits and may be preceded by letters. Take a clear photo of the serial number or write it down exactly as it appears.
If you cannot find the serial number on the back or bottom, check inside the safe by opening the door and looking at the interior of the back panel. Some models have the number stamped on the interior as well. If the safe is bolted to a wall or floor and you cannot access the back, a locksmith can usually read the number from the front or side of the unit.
Removing a bolted-down safe before opening it
If the Delta Force is bolted to a floor, wall, or furniture, you will need to remove the bolts before a locksmith can transport it or before you can access the back panel to find the serial number. The bolts are usually located on the bottom or back of the safe and are tightened with a wrench or socket set.
If you are comfortable using basic tools, you can remove the bolts yourself. Use a wrench that fits the bolt head snugly, and turn counterclockwise. If the bolts are rusted or stuck, spray them with penetrating oil like WD-40 and wait 15 to 30 minutes before trying again. Once the bolts are loose, you can lift the safe away from the mounting surface.
If the bolts are stripped, corroded, or you do not have the right tools, a locksmith or a handyperson can remove them for you. This usually takes 15 to 30 minutes and costs $50 to $100. Once the safe is free, you can proceed with either the manufacturer reset or the locksmith opening.
Resetting a digital keypad Delta Force
If your Delta Force has a digital keypad and you have received reset instructions from the manufacturer, the process usually involves entering a master code or a specific sequence of button presses. The exact steps depend on the model year and the keypad type. Big Green Safe will provide these instructions when you contact them.
A typical digital reset might look like this: press and hold a specific button (often marked with a star or asterisk) for three to five seconds until a light flashes, then enter the master code, then press another button to confirm. Once the reset is complete, the keypad will prompt you to enter a new combination. Write down your new combination in a secure place, such as a password manager or a locked drawer, so you do not lose it again.
If the keypad is not responding or the reset does not work, the battery may be dead. Digital keypads on safes are powered by AA or 9-volt batteries located inside or on the back of the keypad. Replace the battery and try the reset again. If the keypad still does not respond, contact the manufacturer or call a locksmith.
Resetting a mechanical dial Delta Force
A mechanical dial safe does not require batteries and cannot be reset remotely. To reset the combination, you will need to access the lock mechanism inside the safe, which usually means removing the lock assembly from the door. This requires unscrewing bolts from inside the safe and carefully pulling the lock out without damaging the door or the locking bolts.
Big Green Safe will send you detailed instructions and may provide a diagram showing where the bolts are located and how to remove them. The process typically takes 30 to 60 minutes if you are comfortable with basic mechanical work. If you are not, a locksmith can do this for you, or you can contact the manufacturer to arrange a mail-in reset service where you ship the lock to them and they reset it and ship it back.
Frequently Asked Questions
How much does it cost to open a Big Green Safe Delta Force?
A locksmith typically charges $75 to $200 to open a Delta Force, depending on your location and how long the job takes. The manufacturer reset is free if you have proof of ownership. If the locksmith must drill the lock and install a new one, the total cost may reach $250 to $350.
Can I open the safe myself without calling anyone?

Will opening the safe damage it?
