Safety that fits in a pocket

Personal alarms do one thing brilliantly: they make you impossible to ignore. A 125-130dB siren draws every eye within a block, and attackers depend on nobody looking. The same logic protects a hotel room or dorm, which is why this gear lives in a carry-on as happily as on a keychain. We packed the full kit in hotel, Airbnb and dorm safety.

On your keys

The personal safety alarm pulls to activate, no button fumbling, and runs on a replaceable battery. Students walking at night, runners, and anyone who closes late at work keep one within reach.

In the room

The door stop alarm wedges under any inward door: it physically resists opening and screams if the door moves. The portable travel lock adds a lock a landlord, host or hotel never gave you, and removes without a trace.

How to carry it so it actually helps

An alarm only helps if it is reachable in the first second, so clip it where your hand already goes: the outside of a bag strap, a belt loop, the keys you hold on the walk to the car. Pull the pin once at home so the motion is familiar and the sound is not a surprise to you. Check the battery twice a year, when the clocks change. None of this needs an app, a subscription, or a phone with signal, which is exactly why it still works in a parking garage or on a trailhead.

Who this is for

College students (send them off with the dorm safety kit guide), runners and dog walkers out before sunrise, night-shift workers, frequent travelers, and older family members who want help arriving fast without learning any technology. If you live alone, our calm checklist for living alone puts all of this in one evening of setup. For the house itself, start with Door Security, or let the 60-second alarm finder match an alarm to each spot in your home.

Frequently asked questions

How loud are these alarms, really?
About as loud as a siren at arm's length: painful up close and clearly audible down the block. Loud enough that everyone nearby turns to look, which is exactly the point.
Can I take these through airport security?
Yes. Personal alarms, door wedges and travel locks are battery-powered or mechanical, fine in a carry-on, and none of them need Wi-Fi or an app abroad.
How do I use a door stop alarm in a hotel?
Wedge it under the door from inside before bed. The wedge resists the door physically, and the siren fires the second the door pushes against it. Setup takes five seconds.
Who should carry a personal alarm?
Anyone whose plan for a bad moment is 'yell for help.' The alarm yells louder, for longer, and cannot be talked over. Students, runners, night-shift workers, and older family members top the list.
