How We Chose the Best Upright Freezer With Lock
To choose the best upright freezer with lock, we compared upright freezers sold on Amazon in the U.S. on listed capacity, outside width, depth and height, defrost type, the coldest listed temperature, garage-ready ambient ratings, ENERGY STAR status, locks, shelves, drawers and door bins. We checked whether each model is a dedicated freezer or a convertible unit that can also run as a refrigerator, and we read owner reviews for recurring problems such as frost build-up, doors that do not seal, noisy fans and units that arrive dented. We left out listings whose specifications contradicted themselves, and we say so where a figure is the maker’s own claim.
We checked efficiency claims against ENERGY STAR refrigerator guidance and food-safety temperatures against the FDA’s food storage advice (40°F or colder in the fridge, 0°F in the freezer). Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
How to Choose the Best Upright Freezer With Lock
Built-in versus add-on
Factory locks are sturdier; add-on locks fit almost any door.
Who needs a lock
Shared homes, offices, dorms and homes with young children.
Medicine storage
For medicines, follow the label and your pharmacist’s advice.
Spare keys
Store a spare key somewhere safe.
Upright or chest freezer
An upright freezer takes up less floor space and keeps food at eye level on shelves and in door bins, so it is easier to organize and find things. A chest freezer usually holds more for the money and keeps cold air in when you open the lid. Choose an upright when floor space is tight or bending into a chest is hard, and a chest when you want the most storage per dollar.
Tips for Getting the Most From Your Upright Freezer
- Keep keys away from kids. Safety.
- Test the lock regularly. No surprises.
- Clean surfaces before mounting add-on locks. Better grip.
- Do not block the seal. Door must close.
