Buying Guide – How to Choose the Best Key Lock Box for Realtors
Selecting the right key lock box for realtors involves evaluating capacity, installation type, and security features to match your specific workflow needs.
Key Capacity
Consider how many keys you need to store. Standard boxes hold five keys which is enough for a single property but teams may need larger options like the Iron Lock XXL.
Choose a model that can hold all necessary keys to avoid carrying multiple units for different properties.
Installation Type
Decide between portable hanging and wall-mounted options. Portable units are easier to move but can be removed by others.
Wall mounted boxes provide permanent security but require drilling and hardware for installation on a wall.
Combination Security
Look for boxes with resettable combinations offering at least 10000 codes. This prevents unauthorized access when codes are shared.
Ensure the combination can be easily reset when clients change to maintain access control.
Material Durability
Metal bodies such as aluminum alloy or zinc alloy resist rust and physical damage better than plastic. Check for weather resistant finishes.
Invest in a box with reinforced steel or heavy-duty metals if used in harsh weather or high-traffic areas.
Shackle Protection
Vinyl coated shackles prevent scratches on door knobs and painted surfaces during installation. This is vital for maintaining property aesthetics.
Ensure the shackle is sturdy enough to resist prying but flexible enough to fit various door knob sizes.
Weather Resistance
Outdoor boxes must have protective covers for dials or buttons. Weatherproof models protect against rain dust and humidity.
Check for rust-proof claims and dial shields to ensure the box functions correctly in all seasons.
Budget and Brand
While premium brands offer more features, budget options from Puroma provide solid security for basic needs. Compare features against the cost.
Stick to reputable manufacturers like Master Lock or Kingsley for reliability and warranty support.
Internal Organization
Some larger models have trays or hooks to keep keys organized. This prevents keys from falling out or getting mixed up.
If managing multiple properties, look for a box with internal trays to separate keys by property type.
How to Use and Care for Your Key Lock Box for Realtors
Install the box on a stable surface by following manufacturer instructions. For wall units use included hardware and drill into solid material to secure the box firmly.
Reset the combination immediately after purchase. Choose a code that is easy to remember but not obvious to ensure security and avoid unauthorized access.
Regularly clean the exterior and check for rust or damage. Keep the dial cover closed and ensure the shackle is clean to maintain smooth operation.
