Magnet Lock Set – 4/pkg + Key

Installed four of these on the kitchen cabinets in about ten minutes and the low profile means they're basically invisible from the outside. The key is strong enough to pop the latch through the door without any fiddling.

The magnet key sticks to the fridge so I'm not hunting for it, and the locks themselves sit flush inside the cabinet so nothing catches when I close the door. Four locks were enough for the under-sink cabinet and both bathroom drawers.

My toddler is a tiny escape artist and these have ended the great snack-cabinet raids overnight. The key is easy to keep on hand, and the locks themselves sit flush enough that I forget they're there until I need one.
