Buying Guide – How to Choose the Best Key Lock Box for Realtors
Selecting the right lock box depends on your specific access needs and property types.
Installation Type
Consider whether you need a portable box that hangs on doorknobs or a wall-mounted unit for permanent entry points. Portable units offer flexibility while wall mounts provide security against theft.
Choose portable for temporary showings and wall mounts for offices or shared access points.
Key Capacity
Most boxes hold between 5 and 10 keys. For individual homes this is sufficient. For property managers or teams handling multiple units look for larger capacities like the Iron Lock XXL.
Ensure the capacity matches the number of keys and fobs you need to store securely.
Weather Resistance
For outdoor use ensure the box has a weatherproof finish and protective cover for dials. Materials like zinc alloy or aluminum resist rust and corrosion better than plastic or untreated metal.
Select models with protective shutters to shield combination dials from rain and dust.
Security Features
Look for lockboxes with resettable combinations that offer over 10,000 possible codes. Strong metal construction and anti-pry designs prevent unauthorized entry. Some include detachable shackles with vinyl coating to avoid damage.
Prioritize models with anti-cut and anti-pry features to protect your keys from forced access.
Ease of Use
Buttons and dials should be easy to read and manipulate. Push-button entry speeds up client access compared to dialing. Clear numeric displays reduce mistakes during hurried showings.
Choose user-friendly entry methods to minimize frustration for clients and agents alike.
Durability
The lock box should withstand regular daily use without breaking or degrading. Reinforced steel or heavy-gauge metal ensures longevity even in harsh environments like construction sites.
Invest in models with robust construction to avoid frequent replacements.
Price and Value
Budget models offer basic security while premium ones include advanced features like larger capacity or weatherproofing. Assess your frequency of use to determine if investing in a higher-end model is justified.
Balance cost with the frequency of use and security needs for your business.
Portability
If you manage multiple properties across town a lightweight portable box is ideal. Ensure it includes a shackle that fits most door knobs securely without scratching surfaces.
Choose lightweight models with vinyl-coated shackles for portable use without damage.
How to Use and Care for Your Key Lock Box for Realtors
Set a unique four-digit combination code and record it in a secure digital log. Test the lock multiple times to ensure it opens smoothly before handing the code to clients.
Install the box on a protected entry point or door knob using the included hardware. Check the shackle fit to ensure it is tight and secure against tampering.
Regularly clean the exterior with a dry cloth to remove dirt and corrosion. Change the code after every tenant move-out or property sale to maintain security.
