Whether you need a lockable freezer for a dorm, office, garage, or household, the right upright model can add organized storage without taking over the room.

This roundup compares compact Whynter options, larger Upstreman and Antarctic Star freezers, and a replacement key for compatible Frigidaire and Kenmore units.

Best 10 Upright Freezer with Lock and Key Picks for 2026

Compact Security Pick – Whynter 2.1 Cu. Ft. Stainless Upright Freezer

If you need an upright freezer with lock and key for a small kitchen, office, basement, or garage, the Whynter CUF-210SS offers 2.1 cubic feet of compact storage. Its cylinder lock, reversible door, and adjustable mechanical thermostat make it practical for spaces where secure, flexible frozen storage matters.

Best For: Small households, offices, and anyone who wants lockable frozen storage in a compact stainless-steel cabinet.

Pros:

• Includes a cylinder lock and two keys.
• Reversible door helps accommodate different room layouts.
• Removable wire shelf and temperature control from -10°F to 2°F.
• Stainless-steel door with recessed handle.

Cons:

• Only 2.1 cubic feet of capacity.
• Includes one shelf, so storage organization is relatively limited.
• The supplied notes list the specification as not Energy Star rated.

This is a space-efficient choice when security and a stainless finish are more important than bulk capacity. Its compact footprint suits secondary storage, but larger households may need a full-size model.

Replacement Key Set – Frigidaire and Kenmore Freezer Door Keys

For shoppers whose existing freezer already has a lock but needs a replacement, this two-pack of metal freezer door keys may be a practical solution. It is designed for specific Frigidaire, Kenmore, and related models, so matching the listed part numbers and model compatibility is essential before ordering.

Best For: Replacing lost or damaged keys on compatible Frigidaire, Kenmore, Electrolux, Gibson, Kelvinator, or Westinghouse freezers.

Pros:

• Pack includes two metal replacement keys.
• Replaces multiple listed part numbers, including 216702900 and PS426673.
• Wide compatibility list includes specific Frigidaire and Kenmore model numbers.

Cons:

• This is a replacement key set, not a freezer.
• Compatibility is model-specific and should be verified carefully.
• It does not add a lock to a freezer that was not designed for one.

This option makes sense only when your freezer matches the supplied compatibility information. Check the model number and replacement part number before purchase to avoid ordering an incompatible key.

Smallest Lockable Option – Whynter 1.1 Cu. Ft. Black Mini Freezer

The Whynter CUF-110B is a compact upright freezer with lock and key for bedrooms, dorms, offices, garages, and other tight spaces. It provides 1.1 cubic feet of storage, a removable shelf, reversible door, and a cylinder lock with two keys in a black cabinet.

Best For: Dorm rooms, bedrooms, offices, and other locations needing a small amount of secured frozen storage.

Pros:

• Includes a cylinder lock and two keys.
• Compact 1.1-cubic-foot footprint for space-constrained rooms.

• Mechanical temperature control ranges from -11°F to 10.4°F.

Cons:

• Small capacity limits the amount of food it can hold.
• Only one removable wire shelf is included.
• Less suitable for bulk or long-term family storage.

This is a good fit when a lockable freezer must occupy minimal floor space. Its capacity is best treated as supplemental storage rather than a replacement for a full-size freezer.

Large-Capacity Alternative – Upstreman 7.0 Cu. Ft. Upright Freezer

The Upstreman UP-70 provides 7.0 cubic feet of upright storage for bulk meats, frozen goods, breast milk reserves, and extended grocery storage. It is a strong capacity-focused choice for kitchens, basements, garages, or workshops, although the supplied notes do not list a built-in lock and key.

Best For: Households needing organized, high-capacity upright storage with convertible refrigerator/freezer operation.

Pros:

• Large 7.0-cubic-foot interior for bulk storage.
• Convertible temperature range allows freezer or refrigerator operation.
• Five removable glass shelves and a crisper drawer improve organization.

Cons:

• The supplied details do not mention a lock or included keys.
• At 56 inches tall, it needs substantially more vertical space than mini freezers.
• It is not the most direct match for shoppers specifically requiring lockable storage.

Choose this model for capacity and configurable storage rather than security. If an upright freezer with lock and key is a firm requirement, confirm the locking features before buying or consider one of the Whynter options instead.

Best Lockable Mini Freezer – Whynter CUF-301SS

If you need an upright freezer with lock and key for a compact space, the Whynter CUF-301SS combines 3.1 cubic feet of frozen storage with a keyed cylinder lock. Its reversible door, recessed handle, and quiet compressor make it practical for dorms, shared kitchens, bedrooms, or offices.

For shoppers seeking an upright freezer with lock and key plus more room, the Antarctic Star offers 6.0 cubic feet of storage and seven temperature settings. Its compact freestanding design fits apartments, dorms, offices, or homes that need supplemental freezer capacity.

The CUF-301BK offers the same practical lockable, reversible-door format as a compact security-focused freezer, with a black finish. It is a strong fit where controlled access and a smaller footprint are priorities.

Compact Capacity Pick – Upstreman 3.0 Cu. Ft. Upright Freezer

Cons:

• At 2.1 cubic feet, it offers less capacity than the 3.0-cubic-foot Upstreman
• Manual defrosting requires periodic maintenance
• The supplied details list “No Energy Star” under specification met

The Whynter is the clearest match for a compact freezer with a lock and key. Its smaller capacity is a reasonable tradeoff for keyed security, quiet operation, and flexible door placement.

This Whynter is the most space-efficient locked model in the group. Choose it when keyed security and a minimal footprint are more important than storing large quantities of frozen food.

How We Picked the Best Upright Freezer with Lock and Key

We selected products across several useful size and price categories, from 1.1-cu.-ft. personal freezers to 7.0-cu.-ft. household models. The lineup includes lockable compact freezers, larger upright designs, reversible-door options, adjustable shelving, temperature controls, and a compatible replacement-key listing. We also considered where each product is most likely to fit, including bedrooms, dorms, offices, garages, and kitchens.

Product specifications and listed features were prioritized over appearance alone. Because locking systems vary, confirm the exact model, dimensions, electrical requirements, and included accessories before ordering.

Quick Comparison

Best For	Typical Capacity	Standout Consideration
Personal or dorm storage	1.1–2.1 cu. ft.	Small footprint and lower storage volume
Shared spaces or offices	3.0–3.1 cu. ft.	More room while remaining relatively compact
Family or bulk storage	6.0–7.0 cu. ft.	Higher capacity and larger floor-space needs
Replacing a lost freezer key	Not applicable	Verify compatibility by part number and appliance model

Key Buying Factors for an Upright Freezer with Lock and Key

Capacity and Footprint

Choose capacity based on what you freeze most often, not just the largest interior available. Compact units work well for personal meals, ice cream, breast milk, or overflow storage. Larger models are better for bulk meat and family-size inventories, but measure the installation area carefully, including door swing and ventilation clearance.

Locking Design and Access

A lock can help prevent unauthorized access, accidental opening, or shared-space mix-ups. Check whether the lock is built in, whether keys are included, and whether the mechanism is intended for security or basic access control. For a replacement key, match the listed part numbers and appliance compatibility rather than relying only on appearance.

Organization and Temperature Control

Removable shelves, adjustable temperature settings, and a reversible door can make a freezer easier to use. Shelves are particularly valuable in narrow upright cabinets because they separate smaller packages and reduce digging. Confirm that the temperature range suits your storage needs and allow the unit to stabilize after installation.

Placement, Power, and Upkeep

Use a grounded outlet and follow the manufacturer’s clearance recommendations. Garages may experience temperatures outside the appliance’s ideal operating range, so check the specifications before placing a freezer there. Defrosting requirements, noise, energy use, and door-seal quality also affect long-term convenience.

Who Should Buy Which Upright Freezer with Lock and Key?

Choose a 1.1- or 2.1-cu.-ft. Whynter model when floor space is limited or you need a personal freezer for a bedroom, dorm, or office. A 3.0- or 3.1-cu.-ft. unit is a better middle ground for couples, shared workspaces, or modest overflow storage. Select the 6.0- or 7.0-cu.-ft. upright when bulk capacity matters more than portability. If your existing Frigidaire or Kenmore freezer has a missing key, the replacement-key listing may be the most practical choice—but confirm every part-number match first.
