The best chest freezer with lock keeps food, medicine or game secure in a shared garage, a business, a dorm-style home or anywhere children might open it. Most household chest freezers do not include a lock, so the models that do are often commercial or larger units, and the lock design varies from a simple key in the lid to locks built into the handles.
We compared chest freezers on Amazon that list a built-in lock, and noted how each lock works.

How We Chose the Best Chest Freezer With Lock
To choose the best chest freezer with lock, we compared chest freezers sold on Amazon in the U.S. on listed capacity, outside dimensions, the coldest listed temperature, defrost type, any listed daily or yearly energy use, garage-ready ambient ratings, locks, baskets and warranty length. We then read owner reviews for recurring problems such as lids that do not seal, frost build-up, noisy compressors and units that arrive dented, and we left out listings whose specifications contradicted themselves.
We checked efficiency claims against ENERGY STAR’s freezer guidance (certified freezers are at least 10 percent more efficient than the federal minimum, chest freezers are usually more efficient than uprights, and manual-defrost models use about half the energy of automatic-defrost ones) and food-safety points against FoodSafety.gov’s cold storage chart, which says food kept continuously at 0°F or below stays safe indefinitely. 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 Chest Freezer With Lock

Food, game, medication or business stock may need different sizes.
Check the lock type
Key-in-lid, handle locks or hasps all differ.
Keep spare keys safe
Lost keys can mean drilling the lock.
Consider an add-on lock
For a freezer without one, an add-on lock is an option, but check it will not damage the seal.
Size appropriately
Lockable models are often larger or commercial.
Check the warranty
Commercial units may have different terms.
Child safety
Teach children not to play in or on freezers.
