Buying Guide – How to Choose the Best Key Lock Box for Realtors
Selecting the right key lock box involves evaluating several factors to ensure it meets your professional needs.
Capacity
Consider how many keys you need to store in one place. Some models hold five keys while others can manage up to thirty or more for larger teams or multiple properties.
Choose a box that accommodates your current and future needs to avoid purchasing additional units later.
Installation Type
Portable boxes with shackles can be hung on door knobs for temporary use. Wall mounted boxes provide more security for long-term installations.
Select the type that fits your property access requirements and whether you need mobility or fixed storage.
Material Durability
Look for sturdy materials like steel or reinforced aluminum alloy that resist tampering and weather. Metal bodies with protective finishes ensure longer lifespan outdoors.
Prioritize materials that match your climate conditions to prevent rust and corrosion over time.
Weather Resistance
Outdoor boxes should have weatherproof covers or shutters to protect the combination dials from rain and dust. Check for rustproof coatings if installing in humid areas.
Ensure the box is rated for outdoor use to maintain functionality in all seasons.
Combination Security
A code with ten thousand options provides strong protection against guessing. Some models allow alpha numeric combinations for added complexity.
Choose a system that is easy to reset when access needs change to maintain security protocols.
Budget Considerations
Prices vary based on features and capacity. Budget models offer basic functionality while premium ones provide extra durability or capacity.
Balance cost with required features to find a model that meets both security and financial constraints.
Ease of Use
Boxes with push buttons or simple dials are easier for clients to operate quickly. Avoid overly complex systems that might cause access delays.
Select a design that minimizes frustration for frequent users and maintains smooth property showings.
Portability
If you manage properties in different locations consider a portable model that can be moved easily. Some boxes allow you to carry keys between listings.
Ensure the box is lightweight enough to transport yet secure enough to protect keys during movement.
How to Use and Care for Your Key Lock Box for Realtors
When first installing your lock box set a unique combination that you record securely. Test the code multiple times to ensure the mechanism operates smoothly before handing it to clients.
Periodically check the lock mechanism for signs of rust or stiffness. Lubricate the dials or buttons with a silicone based spray to maintain smooth operation in changing weather.
Reset the combination regularly especially after each showing or guest stay. This practice prevents unauthorized access and ensures only current clients have entry to the property.
