Mounting Options
Decide between hanging and wall mount options. Hanging allows for portability while wall mount offers higher security.
Ensure you have the necessary hardware like screws or shackle to secure the box properly.

How to Use and Care for Your Key Lock Box for Realtors
To set up your lock box first open the unit and locate the reset mechanism usually found inside the door. Choose a memorable four-digit code and test it three times to ensure it works properly before closing the box. Record the code securely in your property management system to share with clients or contractors.
Regularly clean the exterior of the box with a soft cloth to remove dust and dirt that might jam the dials or buttons. Inspect the shackle and hinges for signs of rust or wear and apply a light coating of silicone spray if needed to ensure smooth operation. If you notice the buttons sticking in cold weather try lubricating the dial mechanism sparingly.
Always close the shutter or cover after use to protect the combination from weather. If you are using a wall-mounted model ensure the screws remain tight and the box is not loose. Rotate codes every time a tenant or contractor leaves the property to maintain security and prevent unauthorized access.
Frequently Asked Questions
How do I reset the combination on a Master Lock lock box?
Open the lock box and locate the reset wheel or lever inside the door. Slide the reset wheel to the unlock position and enter your new code. Close the door and test the new combination multiple times before using it for property access. If you forget the reset steps check the manufacturer instructions.
Can I use a key lock box in extreme weather conditions?
Most lock boxes are designed for outdoor use but extreme cold can cause dials to freeze or stick. Look for weather-resistant models with protective shutters to shield the mechanism. If you live in an area with harsh winters consider a model with a larger opening to prevent ice buildup.
What is the difference between hanging and wall mount lock boxes?
Hanging lock boxes can be moved easily and are suitable for temporary access or rental properties. Wall mount boxes require drilling but offer higher security as they cannot be easily removed. Choose wall mounts for permanent locations and hanging models for flexibility.
How many keys can a typical realtor lock box hold?
Standard lock boxes hold up to five keys which is sufficient for most residential properties. Heavy-duty models like the Iron Lock XXL can hold twenty to thirty keys which is ideal for commercial properties or large complexes. Choose based on how many keys you need to manage at once.
Is it safe to leave a key in a lock box outside?
It is safer than hiding a key under a mat but still carries risk if the box is tampered with. Ensure the box is mounted securely and codes are changed regularly. Use the box only when necessary and remove keys when not in use to minimize exposure.
Can I use a lock box for both indoor and outdoor access?
Yes most lock boxes are designed for both indoor and outdoor use. Ensure you choose a weather-resistant model if you plan to use it outside to prevent corrosion. Check the product specifications for temperature and weather limits before purchase.
How often should I change the lock box combination?
Change the combination every time a tenant contractor or guest leaves the property. This ensures that only authorized individuals have access to your keys. Frequent changes reduce the risk of unauthorized access due to lost codes or forgotten access.
What should I do if the lock box is jammed?
Try using a light lubricant on the dials or buttons to loosen the mechanism. If it is jammed due to rust or damage contact the manufacturer for repair or replacement. Avoid forcing the box open as this may damage the internal mechanism permanently.
