Our mini storages around here supply you locks. I go around to storage units and find units that have no locks but people have left stuff in them. If there is no lock it means the company has cut it because you didn't pay your bill.If the unit has stuff in them that is worth selling I rent that unit for a month and sell the stuff that's in them. I made 900 just this week. Shoulda paid your bill ;). I've been doing this for 3 years now.
