Customer Reviews

“The visual flash of the LEDs alone when I lock the door really stick in my memory. Locksure has been on my door for over six months now and I want to keep it!”

— Jason, Stevenage

“We have a three story house and, just before bed, I get paranoid if I remembered to lock the door. No more with Locksure, I just check the app and have peace of mind.”

— Belinda, Slough

“The history feature really helps me get to the truth of when the kids came in and out of the house, even when I am in the office!”

— Angela, Hartford
