Type "/climits" to find out how many locks you have, and post how many below! I have currently, 129/500.
I have like 127, or something like that, but like 30 - 40 of those are just because I have a stable in my town covered with signs and trapdoors.
150/300. 50 being double chests filled with potions, 50 more being in an 8-stall stable coveed in furnaces
