What Are the Benefits of a Smart Lock Key Box?
High-tech lockboxes offer more than just secure storage in smart homes. Keep reading to learn more about the features and benefits of smart lock key boxes.
Safe storage: In addition to keys, you can stow away other large items such as key cards, IDs, small folded documents, and other pocket-sized belongings.
Indoor or outdoor use: Thanks to durable, weatherproof construction, you can use smart lock key boxes inside your home and in outdoor settings in cold or hot environments.
Wall or doorknob mounting: Not all lockboxes need to be attached to a doorknob or door handle. They can be mounted to walls or gates, attached to car interiors, or used to secure personal items inside hotel rooms.
Offline security: Most electronic key boxes come with an iOS or Android app, but they also don’t require WiFi to work. If you’re concerned about hackers cutting access to the internet in order to break into your unit, the best smart lockboxes are battery-operated and will continue to keep your belongings safe.
Remote access: If you’re expecting guests, you can grant access to the unit’s contents at a specific date and time or for a certain duration — no matter where you are. Other users don’t need to be tech-savvy, as smart lockboxes can be accessed by approved guests without an app.
Battery power: No need to hire an electrician — smart key boxes are battery-operated and can also be powered up via emergency chargers or other energy sources if they’re running low on juice.
