What it won't do: Stop a determined intruder — no portable device can. What it does: Create a 120dB alarm barrier that wakes you up and scares off opportunistic entry, in any hotel, Airbnb, or dorm room.
You lock the hotel door. But the lock is weak, the chain is flimsy, and you're in a strange city trying to sleep. That uneasy feeling? It's valid.
For people who check the hotel lock twice — and still lie awake listening.
The Lisora DoorDefend slides under most doors in 3 seconds — no tools, no installation. If someone tries to push the door open, the pressure triggers a 120dB alarm. That's louder than a chainsaw. It won't just wake you up — it'll send anyone on the other side running.
It's small and light. Fits in a carry-on, backpack, or purse. And for solo travelers, students in dorms, or anyone who's ever double-checked a hotel lock at 2am — it's the cheapest peace of mind you'll ever buy. One device does the job of a separate door wedge and a standalone alarm — no installation, no tools, no monthly fee.
What's in the box: 1× DoorDefend alarm, 1× user manual. (Requires 1× 9V battery, not included.)

Frequently Asked Questions
How does the DoorDefend work?
Slide it under the door. If someone tries to push the door open, the pressure triggers a 120dB alarm.
Does it need installation or tools?
No. It slides under most doors in 3 seconds — no tools, no installation.
What battery does it need?
1× 9V battery, not included. It is battery powered, so there is no charging.
Will it fit my door?
It slides under most standard inward-opening doors with a small gap underneath — the kind you'll find in hotels, Airbnbs and dorms. It needs that gap to wedge in, so it won't work on a door that sits flush to the floor.

1× DoorDefend alarm, 1× user manual.
