Glad I had it
Tripped on the path behind our houses and hurt my ankle. Pulled this and my neighbour came through the gate to help me up. So glad I had it on that walk.

Happy mum
Both my girls are at college. The clips went straight onto their existing keyrings, no fiddling with those awful split metal rings. They both texted to say thanks, which never happens.

Tougher than it looks
Dropped mine on the pavement halfway through a run. Little scuff on the side but it still works. It has a harder life than my phone lol I feel a lot calmer running at dusk with it on me.

Why you’ll love it
One pull and a 130 dB siren screams until the person following you is gone. It lives on your keys, so it is in your hand on every walk to the car. There is no app, no account and no monthly fee.
Product details
The Keyring Siren Personal Alarm is a rechargeable pull-ring alarm with a 130 dB siren, flashing LED and separate steady flashlight. Pulling the whole ring and cap vertically out of the top starts the siren and strobe; replacing the cap stops them.
The slim body measures 99 × 31 × 13.5 mm and weighs 50 g. It charges through the USB-C port on the bottom and gives an audible and light cue when power is low. The stated continuous runtime is 70 minutes for the alarm and 240 minutes for the light. A rear switch controls the steady flashlight.
This is a manually activated attention signal, without GPS, motion detection or automatic emergency calls. Keep it dry; it is not sold as waterproof.
What’s included
One pink Keyring Siren Personal Alarm with its pull ring, one black key buckle and one white USB-A-to-USB-C charging cable, supplied in a retail carton.

ok I get it now
I thought a noise maker was a bit pointless. Tried mine in our stairwell with my sister downstairs and she came straight up to see what was happening. Keeping it.
She actually carries it
Got this for my daughter at college. She put it on the keys she takes everywhere, which was the whole point for me.
so far so good
Been in my purse with everything else for three weeks and the cap has stayed put. I was worried about embarrassing myself in the grocery store lol
Glad I bought it
I finish work at 11 and the car park is always the bit I hate. Having this in my hand makes that walk feel less awful.
5 stars
Bought one for my sister who runs and one for my mum. Both kept them, neither wanted another candle!
bright!!
My husband could see the flash from the other end of the driveway when we tested it at dusk. Charged it from my laptop afterward. Pretty straightforward.
How it works
1Choose where to carry it
Fasten the buckle to your keyring or a bag loop.
2Pull the ring straight up
Pull the whole ring and cap vertically out of the top to start the siren and strobe.
3Put the cap back
Press the ring and cap back into the top to stop both.
For the walks you make on your own
After a late shift
Keep it with your car keys for the walk through the parking garage.
On a solo run
Give it a reachable place before you leave for the trail.
On the way from the library
Carry it on your backpack for the walk across campus.
In an unfamiliar hotel
Put it within reach of the bed when you’re away for work.
On the early dog walk
Keep one hand on the leash and the alarm in the other.
While you wait for your ride
Take it along for pickups on unfamiliar streets.
Carry it without accidental sirens
The fitted pull cap needs a deliberate 2 lb pull to release. Our controlled bag test put the alarm through 500 everyday jostles without a false activation.

Why a safety instructor recommends this alarm
For someone who doesn’t want to carry spray, I recommend a siren and strobe like this. You can signal without lining up a shot, and there’s no irritant to blow back toward you.
The gift that says get home safe
Parents buy it for daughters heading to college and friends buy it for the one who runs at dawn. It ships free in a gift-ready box.
Women say they stopped dreading the walk to the car
“It’s on my backpack. I can find it without taking the bag off which matters when I leave the library late.”
Aisha M.
Love it
“Three work trips since I charged it and it still works. I put it next to the bed in every hotel, don’t even think about packing it now.”
Corinne B.
Handy
“Another woman on my shift had one. We park in the same far lot and she showed me hers, ordered mine that night.”
Rosa D.
Bought my own
“My sister asked for one after seeing mine so that’s two birthdays sorted.”
Jen W.
Great present
“finally something I remember to bring running. Keep it with my shoes, grab both.”
Kayla P.
Yep
“My daughter gave me this for my evening walks. I’m 72 and prefer something I can understand without her doing all the setting up for me. This suits me.”

Frequently asked questions
Does it come ready to attach to my keys?
Yes. The included black key buckle clips onto your existing keyring.
Will it stand up to everyday knocks?
Yes. In our drop test, all 20 alarms still sounded after ten drops each from a height of one metre onto a hard floor.
Will a charge last between outings?
Yes. A full charge provides twelve months of standby, or 70 minutes of continuous alarm use. Using the siren or flashlight draws down that charge.
Is it straightforward for an older adult to use?
Yes. There’s nothing to pair or program, and one deliberate pull activates it. You don’t have to remember a code or a sequence of buttons.
Can I take it running?
Yes. The included buckle clips onto a running-belt loop.
Can I use a charger I already own?
Yes. The supplied USB-A-to-USB-C cable works with a standard USB-A wall charger or laptop port.
Is US delivery free?
Yes. Every US order includes free tracked shipping.
Can I try it before deciding to keep it?
