As a homeowner, there are so many home maintenance tasks to do, it's impossible to remember them all. That's why we love Lock Check Day, it's a holiday to remind you to do a small but important home maintenance task. This day is all about checking your door and window locks to make sure they're all in working order.
Lock Check Day is a reminder to inspect physical and digital security. It encourages homeowners and businesses to verify that door, window, and safe locks are in working order to prevent break-ins and ensure peace of mind.
The inaugural observance on social media was June 18, 2025, but changed to June 21 annually in 2026.
