A:AnswerHi Mike.
It does not come with a lock included or built in. As far as I know it does not have holes for a lock built-in either.

A:AnswerNot that I am aware of but because of its height and placement it's not all that visable untill you open the door. You may also be able to blacken it out with black tape without it being an eye sore.
A:AnswerNot sure if “Quite hot “ is normal . Mine gets WARM but not HOT . Make sure you have the minimum spacing around the sides and rear of the device .
A:AnswerOf course. That shouldn't be a problem even if your garage freezes. You can use it in your garage, but expect it to use a lot more energy especially in the winter. I have a chest deep freeze in my garage in the summer in Texas. We have lots of days 100+ and I have had no problems with my freezer. Just keep in mind that if it runs constantly then it may not last as long.
