Featuring a robust 56mm wide metal body and a high-security boron alloy shackle, this smart padlock delivers maximum resistance to cutting and sawing whilst eliminating the need for physical keys or memorised combinations.

With no keys to lose or duplicate, you maintain complete control over who can access your secured areas. The padlock includes intelligent backup features for continuous operation. A directional code keypad provides emergency access if your phone battery dies, whilst low battery notifications alert you through both the app and the padlock itself. The battery jump feature allows temporary access even when the battery is depleted whilst the lock is engaged. Power is supplied by an easily replaceable CR2 battery, ensuring minimal downtime.
