The refrigerator and freezer have a built in lock that will come with a key (great for locking your items or even using it as a safe when you don't need it turned on).

Emerson Compact refigerator and freezer can be found brand new on Amazon for $258. I will sell for $100. No longer need it as I just finished school and moved off campus!
