It features a high quality backlit touchscreen and an intuitive interface. Keyboxes open quickly using infrared communication and GPS coordinates assist with keybox assignment, end of showing notification, and locating a missing key.

Supra iBox BT LE

More models of smartphones and tablets communicate directly with the iBox BT LE keybox than any other Supra keybox. No additional hardware is required for most phones, including the newest models of iPhone and iPad. You can check your phone's compatibility on the Compatible eKEY Device List.

iBox BT LE is equipped with the same large key container as the iBox BT, that can hold both gate cards and keys. The shackle is​ completely removed from the key box for easy handling when placing the iBox BT LE on a property.

The iBox BT LE communicates directly with most phones or tablets via infrared (IR), Bluetooth® (BT), and Low-Energy Bluetooth (BT LE) technologies.  Please note that iPhone and iPad devices released before the iPhone 4S require a small adapter to communicate with iBox BT LE keyboxes​​.
