4 Keychain Alarms To Buy Instead Of Fumbling For Your Phone

What do parking garages, creepy alleyways, and dimly lit stairwells all have in common? They're great places to catch the average person off-guard. Unfortunately, we live in a world that's prone to evil-doing. While there's not much rhyme or reason as to when danger may strike, there are plenty of ways to prepare for it. And being more astute when you're in an unfamiliar place won't cost you anything but a little bit more time.

But how about something you can buy to carry around for greater peace of mind? We recommend a good keychain alarm as a go-to emergency device. This is a popular product category on sites like Amazon — with hundreds of manufacturers fighting for your attention — so it pays to know which models to consider and which brands should be avoided; that's why we created this list in the first place.

We combed through page after page of listings to home in on the best keychain devices money can buy, at least in our humble opinion. We also provide a full methodology for how we chose these top-rated Amazon gadgets at the bottom of this roundup. The best offense is a prepared defense, and these keychain alarms are all designed to give you extra protection and time when you need it most.

Whether you're looking to stockpile keychain alarms for yourself or you plan on gifting them to friends, family, and colleagues, the $27 Taiker 140dB Self Defense Keychain (10-Pack) should be a top consideration. There isn't much to it; a simple pull-pin triggers the alarm, which sounds at an ear-piercing 140 decibels for up to 90 minutes. To silence the alarm, you just need to reinsert the pin.

There's also a built-in, push-button flashlight if you need extra illumination on a nighttime walk. Each of the 10 keychain alarms comes with a keychain and lanyard attachment, making it easy to strap the device to handbags, backpacks, luggage, etc. The multi-pack contains several color options, and each keychain is powered by three LR44 button-cell batteries (you'll need a mini-screwdriver to replace the batteries).

On Amazon, this Taiker product scored 4.7 out of 5 stars, based on over 3,400 user reviews. Most folks like how simple and effective the keychain is, and a majority of the feedback was at the 5-star level. That said, we read a few reviews complaining about failed alarms after a short period of time. It's worth knowing about, but we don't think this is a massive quality-control issue.

Next up is the $15 Fauxomor 140dB Personal Safety Alarm, which has a few of the same features as the Taiker product we just discussed. Another push-pin design: once pulled, the Fauxomor alarm reaches up to 140 decibels and wails for up to 60 minutes. A built-in LED strobe light goes off at the same time; unlike the Taiker keychains, though, there isn't a button you can use to manually turn the light/strobe on or off.

The Fauxomor uses three button-cell-style alkaline batteries. Conveniently, the manufacturer thought to include a low-battery alarm that starts chirping once the device dips below 10% battery life. According to Fauxomor, the alarm should last up to three years, though we're assuming mileage will vary based on usage.

Available in three- and six-pack options (each with multiple colors), the alarm earned 4.4 out of 5 stars on Amazon, based on more than 2,100 reviews. People seem to like the set-it-and-forget-it design, which leaps into action the moment you pull the pin. Others weren't so pleased with the alarm volume (more than one user questioned the 140-decibel spec), and a few customers reported dead keychains after a short period of time.

Now for something a bit different, at least in terms of battery life. The $30 She's Birdie 3.0 Personal Safety Alarm doesn't come in a multi-pack like the other units we've talked about, but we'd willingly pay the extra dough for one of its best features: a USB-C rechargeable battery. She's Birdie is kind enough to provide a USB-C cable, too; just be sure to routinely recharge the device (you may want to set up a recurring three-month reminder).

As far as noise, She's Birdie 3.0 tops out at 130 decibels for 120 minutes, and its pull-pin design puts the gadget on high alert as soon as it's needed. The pin also activates the built-in strobe, and both the alarm and light can be turned off by simply reinserting the pin. The product comes with a brass carabiner for clipping onto everyday possessions, and we like that there's a charge-level indicator, too — on the bottom of the device.

There's even a push-button flashlight that could come in handy when the sun goes down. It's a bit pricier than the other two products we've featured thus far, but over 1,700 Amazon shoppers gave the She's Birdie 3.0 a 4.6-out-of-5-star rating. It's also available in numerous colors; we just wish there were a multi-pack option for bulk buys.

Based on your residence, our final selection may not be available to ship (it wasn't for the writer of this article), but we'd be hard-pressed not to mention the $40 Sabre Personal Safety Kit. There's a ton of value built into this three-item bundle, and Sabre is one of the more recognizable personal safety brands on the market. The included keychain alarm rings out at 130 decibels and can be activated with two quick button taps (the button is located at the top of the device).

You can also sound the alarm by pulling the keychain out of the device. Sabre added a built-in flashlight, too; just quick-press the alarm button once to activate, and again to turn it off. The other part of the kit is a 0.54 fl oz canister of OC spray, which supplies enough hot sauce for 25 sprays. The manufacturer claims a single spray should project up to 14 feet, and you can spray for up to 10 seconds per blast. Color options include black, white, and lavender, and buyers can also purchase two kits simultaneously.

User feedback for the Sabre safety kit was pretty strong on Amazon. More than 1,400 customers wrote in, earning the product 4.6 out of 5 stars. 80% of reviews were at the 5-star level, and while we came across a handful of "it died quickly" reports, we're not overly concerned about quality control — especially from a brand like Sabre.

As our headline would indicate, the goal was to pick four handy keychain products that can be used quickly and efficiently in case of an emergency instead of a phone. Safety features were of chief importance, and we made sure that each alarm sounded at 130 decibels or louder, was easy to operate, and included at least one other safety function.

We also leaned heavily on user feedback; the majority of our selections were from less-recognizable, third-party brands, so personal customer experiences were critical. Lastly, we didn't choose any alarm device that scored less than 4 stars on Amazon.
