A 140dB alarm that lives on your keys, so help is one thumb press away instead of buried at the bottom of a bag. Built for night walks, commutes and travel, it stays in your hand from the car door to your front door.
140dB loud personal alarm that fits on your keys
- feeling unsafe when walking alone
- need to attract attention in an emergency
- hard-to-reach safety tool in a bag
One press on your keys, and everyone hears you.
Walking alone used to mean hoping nothing happens while you dig for your phone. Now a 140dB alarm sits on your keys, ready in one press.
Loud enough to be heard across the street

A siren that cuts through the street
Press the raised dome button once and the 140dB siren fires. There is no unlocking, no typing and no menu to find. The speaker grille sits right beside the trigger, so the sound starts the instant your thumb lands.

Lives on your keys
The body is compact and oval, with a keyring so it hangs beside your house key instead of sinking to the bottom of a bag. If you already carry an airtag keychain, this sits on the same ring without fuss.

Three pieces, one ready tool
The alarm, the wrist strap and the split key ring arrive together. Clip it to your keys for the walk to the car, or loop the strap around your wrist when your hands are full.
One press, one hand, no unlocking
- 1Clip it to your keys
Open the split key ring through the eyelet and slide it onto the keys you hold on every walk. Keep it where your hand already goes.
- 2Add the wrist strap
Thread the strap through the loop and wear it on your wrist during dark walks, so the alarm stays in your grip when your hands are full.
- 3Find the dome button
The raised dome sits on the body. Practise finding it by feel with your thumb, so you never need to look down.
- 4Test it safely
Press once in a safe spot, holding the alarm at arm's length and away from your ears and people nearby. Then check it again once a month.

Questions and answers
It is loud by design. That is the point, because the siren is what draws people's attention. Keep it on your keys for daily carry and test it with a short press held at arm's length, away from your ears and anyone nearby.
The body is smooth plastic with a raised dome button, built to ride in a pocket, bag or on a key ring every day. Check the dome button, strap and ring every month and run a brief test press so you know it still triggers.
Yes. It is made for girls, teens, parents of kids and older people who live alone. Show them the one-press motion before the first solo outing, then clip it to a school bag or keyring where the hand already goes.
A whistle gets lost in traffic and city noise, and pepper spray is restricted in some places and slow to reach. This alarm sits on your keys and sounds with one thumb press, with no unlocking and no aiming.
The gold and silver finishes, the matte body and the stainless-look split ring are what keep it looking and feeling solid after months of daily carry. A cheap alarm that sits in a drawer protects nobody, so the value is in one that you actually keep on your keys.
