Setup and Installation
The Greenvelly Biometric Wall Gun Safe is designed for discreet installation between standard wall studs. No assembly is required for the safe itself.
1. Choosing an Installation Location
Select a location within your home that offers sufficient space between wall studs (typically 16 inches on center) and allows for the full height of the safe (53 inches). Consider areas where the safe can be concealed, such as behind a mirror, painting, or within a closet.

2. Preparing the Wall Opening
- Locate two adjacent wall studs using a stud finder.
- Mark the outline for the safe's opening on the wall, ensuring it is slightly larger than the safe's dimensions (18" W x 53" H) to allow for easy insertion.
- Carefully cut out the marked section of drywall or other wall material. Ensure no electrical wires or plumbing are present in the cutting area.
3. Mounting the Safe
- Slide the safe into the prepared wall opening. Ensure it sits flush with the wall surface.
- Using the pre-drilled holes on the safe's frame, secure the safe to the wall studs with the provided expansion screws. Use a drill to create pilot holes if necessary.
- Tighten all screws firmly to ensure the safe is stable and cannot be easily removed.

Operating Instructions

1. Battery Installation
The electronic lock requires [Number] AA batteries (not included). Locate the battery compartment on the inside of the safe door. Insert the batteries, ensuring correct polarity. Close the compartment cover.
Important: If the batteries are depleted, the safe can still be opened using the emergency key. An external battery pack may also be available for temporary power (refer to product specifications for availability).
2. Initial Access with Emergency Key
Before programming any electronic access, familiarize yourself with the emergency key access:
- Locate the emergency keyhole, usually concealed behind a cover on the keypad panel.
- Insert one of the provided emergency keys and turn it to unlock the safe.
- Turn the knob to open the safe door.
Warning: Store emergency keys in a secure, separate location, away from the safe and out of reach of children.
3. Programming a User Code (Keypad Access)
- With the safe door open, press the internal programming button (usually a red button or a button marked "SET" or "PROG"). The keypad will beep, and an indicator light will illuminate.
- Enter your desired 4-8 digit user code.
- Press the "#" or "ENTER" button to confirm. The safe will beep to indicate successful programming.
- Test the new code with the door open before closing it.
4. Registering Fingerprints (Biometric Access)
The safe can store multiple fingerprints. Refer to the specific instructions provided with your safe for the exact number and procedure, as this can vary slightly by model.
- With the safe door open, press the internal programming button. The fingerprint scanner will activate, and an indicator light will flash.
- Place your finger firmly on the scanner. Lift and repeat several times from different angles until the safe confirms successful registration (usually with a series of beeps or a green light).
- Repeat for additional fingers or users as desired.
- Test registered fingerprints with the door open before closing it.
5. Opening the Safe
- Biometric: Place a registered finger on the scanner. If recognized, the lock will disengage. Turn the knob to open.
- Keypad: Enter your programmed user code, then press "#" or "ENTER". If correct, the lock will disengage. Turn the knob to open.
- Emergency Key: Use the emergency key as described in "Initial Access with Emergency Key" above.
6. Adjustable Shelves
The safe includes three adjustable shelves to customize your storage space. To adjust, simply unclip or slide the shelves from their current position and re-insert them into the desired slots along the internal rails. This allows for flexible organization of firearms, ammunition, and other valuables.
