Please tell me, I am stuck hard on Level 4. It's been months.
remember you can push whole locks even if only half an edge is sticking out
maybe I am too simple minded for this, I can't find where to apply that hint
The first step is push the top key left, then unlock both locks. You can then push up against the half lock from the top lock. Lemme know if you still need help.
Got it, thank you so much.
