About the Smart Lock Signal black outline icon
A square-bodied padlock with a rounded shackle and a round keyhole above a short slot emits two curved signal arcs from its upper right corner. The pairing of lock and wireless waves reads as connected security, fitting smart home apps, keyless door entry systems, IoT device dashboards, hotel access panels and rental property listings.
The lock body is wide and squared with softened corners, and the arcs are spaced so the signal stays legible without crowding the shackle. Its weight matches key, fingerprint and door sensor icons in the same smart home set. Place it at 24 px or larger so both arcs remain separate.
This is the black outline version of the smart lock signal icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
