About the No Lock Sign color filled icon
A square-bodied padlock with a rounded shackle and a small keyhole sits inside a circle crossed by a diagonal bar. The pairing reads as locking not permitted or access left open, so it works on emergency exit and fire door notices, storage and gym locker rules, unlocked or unsecured status states in an app, and slides about open data or removed restrictions.
The padlock is centered and squared off, giving the diagonal stroke a clean run across the body without hiding the keyhole. Use it opposite a plain padlock icon to contrast locked and unlocked states, and give it at least 24 px so the shackle stays distinct from the ring.
This is the colour filled version of the no lock sign icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
