    The padlock does not use a keypad but a directional pad that can be changed via the Masterlock app that must be downloaded and connected to the specific padlock. Everything is done securely via Bluetooth and special codes. As for the shackle dimensions, it is as follows: 11/32in (9mm) x 2in (51mm) x 15/16in (23mm).
