Best Coop Locks and Latches That Raccoons Cannot Open

A coop is only as secure as its weakest fastener. Raccoons have dexterous hands and real patience, and a simple hook, turn button, or slide bolt is well within reach for them. The fix is a latch that needs two separate motions, or a bolt secured with a spring clip or padlock. What varies is build material, whether the hardware resists rust, and how easily you can work it with cold or gloved hands. We weighed how many steps each latch takes to defeat, how solidly it mounts to thin coop panels, and whether the finish survives a wet winter. Two-step barrel bolts with clips suit main pop doors and nest box lids. Spring-loaded gate latches suit run gates you pass through daily. Add a padlock where bears or people are a concern, and always test each fastener yourself using one hand.
