Alarms protect against break-ins. But what about walk-ins?
You install alarms, cameras, and sensors to protect against forced entry. But a quarter of burglaries happen because someone simply forgot to lock the door. No smashed window. No forced lock. Just a handle that turned.
Your alarm is armed, cameras are rolling — but if the door isn’t locked, a burglar can walk right in without triggering anything. That’s the gap Locksure fills.
It monitors the actual lock position — not just whether the door is open or closed. Your customer knows their door is locked, not just shut. And you’ve completed the security picture with a 5-minute add-on that earns you £23–69 per customer.

We installed it in a large building where doors get opened manually from inside but the alarm still sets while unlatched. Visitors open the door and trigger the alarm. Locksure lets us see the lock state remotely before sending an engineer out. Saved us three false alarm callouts in the first week.
I’ve started mentioning it on every domestic alarm install. The pitch is easy: ‘Your alarm tells you if someone breaks in — this tells you if you forgot to lock up in the first place.’ About one in three customers add it on. That’s £26-39 extra per job.
We fit a lot of elderly care packages — pendant alarms, door sensors, the lot. Families always ask ‘but how do we know Mum locked the door?’ Now we have an answer.
