Safety and Security — FAQ
How do I choose between adhesive and magnetic locks?
Choose adhesive for quick installation, lower cost, and versatility on various surfaces. Select magnetic for maximum security, complete invisibility, and when you have high-risk items like medications or sharp objects. Magnetic locks require keeping track of a magnetic key but offer superior toddler resistance that most children cannot defeat before age five.
Will these damage my cabinets?
Adhesive locks may peel paint or finish when removed, especially if installed for extended periods. Minimize damage by using a heat gun during removal and pulling parallel to the surface. Magnetic locks with adhesive mounting cause the same potential issues. For zero damage, consider screw-mounted options on hidden cabinet interiors or accept that minor touch-up painting may be necessary.
How many locks do I need?
An average kitchen requires 6-8 locks for lower cabinets and drawers. Add 2-4 for bathrooms, 2-3 for laundry rooms, and 1-2 for other accessible storage. Count every drawer and door within your child's reach, including oven doors and toilet seats. Buying a multi-pack of 12 or 20 ensures coverage for unexpected areas and provides spares for replacement.
Can I remove and reuse them?
Most adhesive locks cannot be reused once removed—the adhesive loses strength. Some magnetic systems allow you to remove the locking mechanism while leaving the base plate installed, enabling temporary disablement. For true reusability, choose screw-mounted designs or accept that adhesive locks are single-use consumables that you'll replace if moving homes.
What surfaces work with 3M adhesive?
3M adhesive bonds best to clean, flat, non-porous surfaces like painted wood, laminate, metal, and glass. It struggles with textured, porous, or greasy surfaces. Always clean with alcohol, dry completely, and apply firm pressure for 30 seconds. Test adhesion with a temporary sticker first. For problematic surfaces, screw mounting remains the most reliable option.
At what age can I remove them?
Remove locks when your child consistently demonstrates impulse control around dangerous items, typically between ages 4-6. Most experts recommend keeping kitchen and bathroom locks until age 5. Observe your child—if they respect boundaries, understand danger, and ask before opening unfamiliar items, they may be ready for gradual lock removal. Start with low-risk areas first.
