The Best Self-Defense Keychains of 2019

Table of Contents

Oftentimes, self-defense keychains are purchased as a gift for someone; a father buying a little insurance for his daughter as she goes off to college, concerned parents looking out for their children, or a spouse giving his wife a self-defense option for her morning run.

Self-defense keychains are not the end-all-be-all of security. They’re non-lethal, portable, and easy-to-use, which makes them the ideal solution for someone who needs just enough time to make their escape in an attack. They can even be designed to not inflict harm, like a loud siren that works to get the attention of someone who can help. No matter what form they take, however, they’re all there to provide a little extra assurance in an emergency. For the best self defense keychain, keep reading below.

Freeasy Stay Safe Personal Alarm Keychain

Unlike other alarm self-defense keychains in the category, the Freeasy Stay Safe Personal Alarm is designed to be gender-neutral, sleek and multifunctional. With an embedded compass, a loud, 130-decibel push-button alarm, and a built-in LED light, this self-defense tool wouldn’t be out of place on a college campus or on a three-day hike.

Pros: These self-defense keychains come in a pack of three, so you can outfit multiple people. It’s also USB charged, which is great for not needing to worry about replacing potentially hard-to-find batteries. Finally, we mentioned this earlier, but the sleek design stands out in a category that’s often dominated by pinks and other, more attention-grabbing colors.

Cons: While the LED is great for seeing in the dark, it may be a little dim to use as an actual security deterrent.

Oranlife Kubotan Self-Defense Keychain

Of the more weapon-styled self-defense keychains, kubotans are a popular option compared to brass knuckles or knives because of their reach. This pack of nine self-defense keychains is a great value, enabling you to have a self-defense tool on hand at multiple locations, should you forget your keys.

Pros: Kubotans are ridged for an easy grip to grab in an emergency. On the other hand, they’re lightweight enough to deliver a non-lethal blow that will incapacitate an attacker. Not only that, but these self-defense tools are strong enough to break a car window, which is a potentially life-saving feature if you’re trapped in a vehicle.

Cons: These self-defense tools are made for a specific application, so if you’re not comfortable with physically engaging with an attacker, this style of keychain may not work for you.

Best Stun Gun Self-Defense Keychain

Guard Dog Security Elektra Keychain

Disguised in what looks like a lipstick container, this stun gun keychain is a powerful self-defense tool, packing an ultra-high voltage that can stop an attacker in his tracks. This rechargeable, multi-use device also features a super bright flashlight that can be used as a visual distress signal and a disorienting force.

Pros: The main plus here is how powerful this device is in such a small package. With an estimated three million volts, this police-grade stun gun keychain fits easily in a purse or pocket and can immobilize a would-be attacker. Of course, the fact that it’s disguised in such an innocuous manner is a huge advantage for you. 

Cons: The battery can last months on a charge, but telling when the stun gun needs to be charged isn’t as clear as it should be.

Best Pepper Spray Self-Defense Keychain

SABRE Pepper Gel Spray Keychain

Pepper sprays shoot a controlled pepper gel up to ten feet. It’s safe to discharge indoors, and its included whistle adds a whole extra element of self defense and security.

Pros: The quick-release keychain makes the pepper spray canister easy to use when the keys are tough to access, like when they’re in a car ignition. The fact that the pepper spray gel can be discharged inside makes it ideal for college students. The fact that the package also includes a 120-decibel whistle is a great bonus.

Cons: As with all pepper sprays, there are restrictions on where this item can be shipped; Arkansas, Washington DC, Hawaii, Massachusetts and New York are all no-go zones.

Best Family Self-Defense Keychain

KOSIN Safe Sound Personal Alarm

Featuring six personal alarms of varying colors, this package is perfect for outfitting your entire family with easy-to-use self-defense alarms. With the push of a button, these ultra-loud keychain alarms alert anyone nearby to danger.

Pros: With a blaring 140-decibel siren, these self-defense keychains are some of the loudest on the market. Not only do they scream, but their included LEDs create a visual distress signal as well. The keychain alarms run on long-lasting replaceable batteries that can last over a year.

Cons: We found that the build quality could have been a little better; while they’re lightweight, the trade-off is that they feel a little less sturdy.

Self-Defense Keychain Methodology

Best Self-Defense Keychains Review
Parking structures can be low-security places and sites of attacks.

With self-defense keychains, there are some considerations that we made based on how widely available these tools are. For example, pepper spray and stun guns are some of the most aggressive and effective non-lethal self-defense tools, but because there are state-by-state restrictions on where the devices can be sold, we decided to try and keep our advice as universal as possible.

  • Multi-Purpose Usability: Many self-defense keychains on the market are big, bulky and only serve one function. If you’re going to have a device you’re going to carry every day, we felt it was important that the device be a lightweight and as usable as possible. To that end, we favored a device that would be an alarm and a light for example.
  • Alarm Strength: Granted, not all of our selections were alarms, but the alarms that we selected needed to be strong. If you’re in an attack, it was important to us that the alarm be able to not only alert passersby, but also act as a disorienting deterrent to an attacker. We found that 130 decibels and louder hit that baseline.
  • Attractiveness: Too many self-defense keychains are gaudy and unattractive, with bulky designs and pink housings. We favored subtle, sleek designs that could be carried with confidence.

Self-Defense Keychain Tips

An important thing to consider when selecting a self-defense keychain is who the tool is going to be used by. If you’re getting it to be used on a college campus, what makes the most sense for that environment? Or, if it’s for a little added security on a nighttime or early morning run, what type of device would work best there?

  • Regulations: We mentioned this before, but there are state-by-state restrictions on purchasing stun guns and pepper spray. Make sure to do your research beforehand!
  • Weight: When selecting a self-defense keychain, take note of the device’s size and weight. This is something you’re going to presumably be carrying around all day. You want to make sure it won’t be inconvenient.

Recap of the Best Self-Defense Keychains of 2019
