2-3 locks. Or padlocks. Different kind of locks. Much different kind of locks or padlocks. Maybe a very strong and unique one. One with a completely different kind of key, and near completely closed of. They might have experience with one, but not with all of them. They might have the tools to open one, without leaving evidence, but not for all of them. - (sometimes it's not that hard to break through, but atleast then it's known someone was inside) -
