Built to Solve a Real Problem
Locksure started on a street where elderly residents were being watched by opportunistic criminals. We needed a way to check their doors were locked — without replacing their locks or taking away their independence.
So we built something simpler. A device that sticks onto your existing lock, monitors whether it's locked, and sends the status to an app. No lock replacement. No loss of control. Just peace of mind.
We patented the design, and now locksmiths across the UK are using it to give their customers the same peace of mind — while earning £13-23 per install.
