Short answer: If you want to help keep children out of cabinets while keeping everyday access convenient for adults, F8 is our top pick for no-drill installation across compatible cabinets, drawers and refrigerators. For cabinets and drawers where you want the lock hidden from view, choose F5. Check your opening's dimensions and installation requirements before buying either model.

Key takeaways
Start with the opening you need to secure: cabinet doors, drawers and refrigerators have different fit requirements.
F8 is our first choice for families who want a no-drill option across several compatible storage locations.
F5 is our second choice when the priority is locking furniture while keeping the hardware out of sight.
Check that every caregiver can open the lock and secure it again after use; keep cards and phones away from children.
No device is completely childproof. Correct installation, safe storage and regular checks remain essential.
Our top 5 at a glance
This Bestkid editorial shortlist prioritizes flexible caregiver access, installation style and suitability for everyday family storage. Bestkid sells the first two products. The order reflects those priorities, rather than a measured ranking of resistance to children.
Rank | Product | Our category pick | Main consideration
1 | Bestkid F8 | Flexible smart access across compatible storage and refrigerators | External hardware remains visible
2 | Bestkid F5 | Hidden smart access inside furniture | Furniture-focused fit and battery maintenance
3 | Safety 1st Secure-to-Explore Adhesive Magnetic Locks | Hidden, battery-free magnetic access | Keep the magnetic keys accessible to adults only
4 | Safety 1st Spring-Loaded Cabinet & Drawer Latch | A simple internal manual latch | Reassess whether your child can operate the release
5 | Dreambaby Twist 'N Lock Multi-Purpose Adjusta-Latch | An adjustable adhesive strap | Visible strap and manual release
1 Bestkid F8 Our pick for versatile smart access
Bestkid F8 combines palm-vein recognition, an RFID card and the eSmartLock app. Its adhesive mounting and flexible coated cable suit compatible refrigerators, freezers, cabinets and drawers.
Why it ranks first: For a family planning access control across several kinds of household storage, that broader placement range earns F8 our first position. Palm-vein access also gives an authorized adult an option without presenting a card.
Compared with F5: F8's external housing and cable remain visible. Parents who prefer uninterrupted cabinet fronts may find F5's hidden installation more attractive. F8 uses rechargeable power and USB-C charging; F5 uses replaceable AAA batteries.
Best fit: Families who value palm-vein access and flexible placement more than concealed hardware. Confirm the exact surface, door gap and cable route before choosing it.
2 Bestkid F5 Our pick for hidden smart cabinet access
Bestkid F5 installs inside cabinets, drawers and wardrobes. Access options include RFID cards, compatible smartphone NFC, a Bluetooth app and a compatible Apple Watch. Adhesive and screw mounting are available.
Why it ranks second: F5 keeps hardware out of sight while giving caregivers several authorized access options. For furniture where appearance matters most, it may be the better match of the two.
Compared with F8: Its intended applications focus on furniture rather than F8's refrigerator and freezer use. It does not offer F8's palm-vein method. Phone and watch compatibility should be checked before buying.
Battery consideration: F5 takes two AAA batteries. Bestkid states that it automatically unlocks when the batteries are fully depleted. Replace batteries promptly after a warning so the cabinet continues to restrict access.
3 Safety 1st Secure-to-Explore Adhesive Magnetic Locks
What works well: These locks attach discreetly inside compatible cabinets and drawers using adhesive. The selected pack includes 20 locks and two magnetic keys, making it an option for multiple storage units without battery upkeep. View the official product.
What to consider: A misplaced magnetic key can interrupt adult access, so assign a consistent storage spot out of children's reach. Compared with F8 and F5, this model uses a separate magnetic key rather than offering electronic alternatives. It shares F5's hidden appearance, but not its configured phone or app access.
4 Safety 1st Spring-Loaded Cabinet and Drawer Latch
What works well: This battery-free latch installs inside cabinets or drawers and uses a wide manual release surface. The ten-pack is useful when several compatible units need a straightforward latch. View the official product.
What to consider: Unlike F8 and F5, access depends on operating a mechanical release rather than an authorized electronic credential. As children grow and their reach and coordination improve, some may learn to operate it. Recheck suitability as your child's abilities change.
5 Dreambaby Twist 'N Lock Multi-Purpose Adjusta-Latch
What works well: Its flexible, adjustable strap and 3M adhesive installation offer a no-drill option for compatible cabinets and cupboards. The selected version comes in a six-pack. View the official product.
What to consider: The strap is visible, and adults operate a manual Twist 'N Lock release instead of F8 or F5's electronic access methods. As children develop their observation and coordination skills, some may learn the release sequence. Check both the child's changing abilities and the adhesive condition regularly.
What Bestkid’s internal comparison found
According to internal test records supplied by Bestkid, 10 children aged 2–5 each tried to open every correctly locked product on a compatible, secured empty cabinet or drawer, with up to 30 seconds per product. In a separate adult task, 10 adults each made five single-attempt unlocks per product using the specified method, giving 50 attempts per model.
Product | Children opening within 30 seconds | Successful adult unlocks | Adult method tested
Bestkid F8 | 0/10 | 47/50 (94%) | Palm-vein recognition
Bestkid F5 | 0/10 | 46/50 (92%) | RFID card
Safety 1st magnetic lock | 1/10 | 45/50 (90%) | Magnetic key
Safety 1st spring-loaded latch | 3/10 | 43/50 (86%) | Manual release
Dreambaby Adjusta-Latch | 2/10 | 44/50 (88%) | Manual twist release
Where F8 and F5 stood out: Both recorded the lowest number of child openings in this comparison. F8 also had the highest observed adult unlocking success at 94%, followed by F5 at 92%. For example, that compares with 86% for the spring-loaded latch: four more successful adult attempts for F8 across 50 attempts. These figures describe the tested installations, participants and methods.
For parents, that combination addresses two everyday needs: limiting children's opportunities to rummage through stored items or reach things they should not handle, while allowing authorized adults to get in. Correct installation, safe storage and supervision remain part of that routine.
How do these cabinet locks control access
A manual latch requires a particular release action. A magnetic model requires its key. An electronic lock requires a configured access method. This changes what adults need to carry or do each time they open storage.
For parents, the practical question is whether the chosen routine is easy to follow consistently. A lock left disengaged cannot provide the intended barrier. The U.S. Consumer Product Safety Commission's childproofing guidance stresses correct installation and reengagement after use, and explains that no safety device is completely childproof.
F8 or F5 choose around your home and routine
Start with the location. If your plan includes a compatible refrigerator as well as furniture, consider F8. If you are outfitting cabinet doors, drawers or a wardrobe and want the hardware concealed, consider F5. The difference is a reason to match each location individually rather than buy one model for every opening.
Then consider the caregiver. Decide which authorized method each adult will actually use. Keep cards and phones out of children's access, protect app accounts, and avoid enrolling a child whose access you intend to restrict. Several available methods are useful only when the household has set them up correctly.
Balance appearance with access. Visible hardware may be an acceptable tradeoff on a utility cabinet, while a fitted kitchen may make concealed installation a higher priority. These are household preferences, not measures of protective strength.
In a separate internal appearance assessment supplied by Bestkid, 10 adults rated the installed F5 an average of 4.4/5 and F8 3.9/5. That preference result favors F5 when a discreet furniture finish matters most.
What affects performance and what are the limits
Door geometry, mounting surfaces, alignment and everyday wear can affect whether a lock closes securely. An adhesive model needs an appropriate clean surface and the manufacturer's specified curing time. Hidden hardware still needs enough internal clearance.
Check protection again when a child becomes taller or learns a new opening action. This applies to every model, including electronic products: credentials left within reach or a lock not secured after use can change access.
Cabinet locks support a wider storage plan. The American Academy of Pediatrics' poison-prevention guidance recommends keeping potentially poisonous products locked, out of sight and out of reach. Keep products in their original containers and do not assume an ordinary furniture lock is suitable for every hazardous item.
How to choose and set up your lock
Identify the exact opening and what is stored behind it. Check the manufacturer's intended use before ordering.
Measure the available space and inspect the surface, door movement and mounting position.
Follow the supplied installation instructions, including adhesive curing or screw placement requirements.
Have each caregiver check their configured access method, then confirm that the door is secured again after closing.
Set a maintenance routine for the mounting, release mechanism, credentials and batteries where applicable.
For a compatible F8 installation, include the cable route in your checks. For F5, pay particular attention to internal alignment and battery warnings. Neither should be assumed suitable for a heated appliance without explicit model-specific approval.
