Learn how to install magnetic cabinet locks in minutes. Step-by-step guidance for positioning, sticking, and testing childproof locks on cabinets and drawers.

Quick answer

Install magnetic child safety locks by aligning the magnetic catch on the door and the striker on the frame, then pressing firmly with the pre-applied adhesive. Test the alignment before you commit to the stick-on placement.

Why magnetic locks beat traditional latches

Magnetic cabinet locks are hidden from view once fitted, so they keep cabinets and drawers looking clean while still stopping toddlers from opening them. Unlike latch-style locks, there is no visible hook or button for little fingers to fiddle with.

The stick-on design means you do not need to drill holes or screw into your cabinet doors, which is a real advantage if you rent or want to avoid permanent damage. The trade-off is that the adhesive bond depends on a clean, smooth surface, so preparation matters more than with screw-fixed locks.

Choosing the right spot for each cabinet

Placement is the difference between a lock that works every time and one that jams or pops open. The magnetic catch needs to sit flush against the striker, so you need a flat area on both the door and the cabinet frame.

For drawers, position the lock near the top edge so the magnet aligns naturally when the drawer is closed. For cupboards with two doors, mount the catch on the inside of one door and the striker on the frame, or use a separate lock per door if you want both secured.

Installation steps

Clean the surfaces: Wipe both the inside of the cabinet door and the frame with a damp cloth and dry thoroughly. Any grease, dust, or moisture will weaken the adhesive bond. Checkpoint: Let the surfaces air-dry completely before sticking.
Dry-fit the lock: Hold the magnetic catch against the door and the striker against the frame without removing the adhesive backing. Close the door to test the alignment—the two parts should meet squarely with no gap. Checkpoint: If the parts do not line up, reposition them before you peel the backing.
Peel and press: Remove the backing from the 3M™ adhesive pads and press each part firmly onto its surface. Hold for at least 30 seconds to ensure a strong initial bond. Checkpoint: Press harder on the striker side, since it takes the most force when the door is pulled.
Test with the key: Use the magnetic key to unlock and open the cabinet. Confirm the door stays closed without the key and that the lock releases smoothly when you swipe the key over the catch. Checkpoint: If the door still opens, re-check alignment—do not just press harder.
Wait before heavy use: Let the adhesive cure for 24 hours before letting your toddler pull on the door. This gives the 3M™ pads time to reach full strength. Checkpoint: Re-test after 24 hours to confirm the bond is still solid.
