Setup
1. Setting the Combination Code

- Set the dials to the default code (0-0-0-0) to open the key box.
- Inside the open compartment, locate the RESET button (a small lever). Push the RESET button from position A to position B.
- While the button is in position B, set your new desired 4-digit combination on the dials.
- Push the RESET button back from position B to position A to lock in your new code.

2. Installation Methods
The Puroma Key Lock Box offers two convenient installation options:
Option A: Hanging with Removable Shackle
The lock box comes with a removable steel shackle, allowing it to be hung on a doorknob, fence, or other suitable location.
- Open the lock box compartment.
- Locate the inner button (usually on the side of the shackle housing). Push this button from right to left.
- While holding the button, pull the shackle upwards to detach it.
- To reattach, align the shackle with the holes and push it down until it clicks into place.

Option B: Wall-Mounted Installation
For a more permanent installation, the lock box can be securely mounted to a wall using the provided screws and expansion plugs.
- Open the lock box compartment and remove the shackle if attached.
- Place the back of the lock box against the desired wall surface and mark the position of the 4 mounting holes with a pencil.
- Using an impact drill, drill holes at the marked positions.
- Insert the provided expansion plugs into the drilled holes, tapping them gently with a hammer until flush with the wall.
- Align the lock box with the installed plugs and tighten the screws with a Phillips screwdriver until secure.

Troubleshooting
While the Puroma Key Lock Box is designed for reliable operation, here are some common issues and solutions:
- Difficulty opening: Ensure the dials are precisely aligned with your set combination. Sometimes, slight misalignment can prevent opening.
- Stiff dials: If the dials are hard to turn, apply a small amount of silicone spray lubricant to the dial mechanism.
- Forgotten combination: If the combination is forgotten, there is no master key or backdoor to open the lock box without the correct code. It is crucial to record your combination in a secure place.
