unfasten

Undo the buckle

To unfasten is to undo or release something that has been fastened—buttons, buckles, latches, straps, or any kind of closure or attachment: She unfastened her seatbelt, He unfastened the gate.

The word implies reversing a secured state, making something loose or free that was previously held in place.
