3. Setup and Installation

3.1. Mounting the Key Safe

1. Select a discreet and secure location for mounting the key safe.
2. Using the key safe as a template, mark the desired drilling points on the wall.
3. Drill pilot holes appropriate for your mounting hardware (screws and anchors, not included).
4. Securely attach the key safe to the wall using suitable fasteners. Ensure it is firmly fixed and cannot be easily removed.

3.2. Setting Your Combination

The Master Lock 5423D uses a resettable combination. Follow these steps to set your personal code:

1. Open the key safe door. (If it's new, it might be open or have a factory default code like '0000' or '1234'. Refer to packaging for initial code if applicable.)
2. On the inside of the door, locate the reset lever or button.
3. Move the reset lever to the 'SET' position (or press and hold the reset button).
4. While the lever is in the 'SET' position (or button held), enter your desired combination on the keypad. Your combination can be any sequence of numbers, and can include repeated numbers.
5. Return the reset lever to the 'NORMAL' or 'LOCK' position (or release the reset button).
6. Test your new combination with the door open first to ensure it works correctly before closing the safe.
7. Scramble the buttons after setting the combination to prevent accidental opening.

Important: Do not forget your combination. Master Lock does not retain combinations for push-button key safes.

4. Operation

4.1. Opening the Key Safe

• Regularly inspect the key safe for any signs of wear or damage.
• Keep the keypad clean and free of dirt or debris. Use a soft, damp cloth for cleaning; avoid abrasive cleaners.
