i am setting up my tank and that is one of the things i needed to figure out. i have a 3 year old so the old kid of kid locks wouldn't work, he could get in them. i just bought a new kid of child proof lock from Lows. it uses a magnetic key! you have to drill almost through the cabinet from the back but you don't see anything from the front when it's closed. then when you want to open the door just place a magnet on the face of the door and it unlocks! i thought i was going to have to put some ugly keyed lock in my cabinet doors, but these work great!
just thought i'd let everyone know about it!
