Here’s the truth about self-defense: The best tool is the one you actually have with you. This Keyguard is so small and lightweight that you’ll carry it everywhere without thinking about it – which means it’s there when everything goes sideways.
Who This Pepper Spray Is Best For:
- People who want discreet protection that doesn’t scream “I’m carrying pepper spray” to everyone around them
- Anyone who’s tried carrying larger pepper spray and keeps leaving it at home because it’s too bulky
- Urban commuters who navigate parking garages, transit stations, and other confined spaces where threats get close fast
- Budget-conscious buyers who want Mace reliability with the option to refill rather than replace
Is This the Right Pepper Spray for You?
Choose Mace Keyguard if you want:
- The absolute smallest pepper spray that still delivers effective stopping power for close encounters
- Something so lightweight and compact you’ll carry it every day without excuses or hassle
- Easy refillability to keep your protection current without buying a whole new unit every few years
Key Features: Don’t let the size fool you – this mini unit packs the same 10% oleoresin capsicum formula as larger Mace products. You get 6 one-second bursts with an effective range up to 5 feet. Now, 5 feet isn’t a lot of distance, so let’s be clear about what this means: The Keyguard is for close-quarters situations where someone is right on top of you. Think parking garage, elevator, or someone following you to your car. At that range, you’re aiming right at their face from arm’s length, and the stream pattern delivers concentrated pepper formula directly to the eyes and nose.
The hinged safety cap is one of those simple features that makes all the difference. One-handed operation means you can flip it open with your thumb while your other hand is full of groceries, phone, or fighting off an attacker. The stream spray pattern is ideal for this application because it gives you accuracy without the drift you’d get from fog or mist patterns. Each burst delivers enough OC to cause intense burning, temporary blindness, and respiratory distress lasting 30-45 minutes. The black finish keeps it understated and professional-looking on your keyring.

Practical Details: The unit measures 3.31 inches long by 0.5 inches wide and weighs just 0.2 lbs. It comes with a keyring attachment. The canister contains 0.14 oz (3 grams) of pepper spray formula. Here’s the smart part: when it’s empty or expired, you can buy a Mace Brand Refill Unit and pop in a new cartridge instead of replacing the whole thing. Mace provides a 1-year warranty on the canister and nozzle. The stream formula works in a wide temperature range, though extreme cold below 32°F may reduce pressure slightly.
Add the Keyguard to your keys and carry real protection everywhere you go. Be Prepared and Be Safe!
Frequently Asked Questions
Is 5 feet of range really enough to defend myself?
For the situations this unit is designed for, yes. Five feet is roughly arm’s length plus one step. If someone’s threatening you in a parking garage or following you into an elevator, they’re already inside that range. The Keyguard excels when there’s no room to run and you need to create an escape opportunity right now. If you regularly walk in open areas where threats could come from farther away, consider a longer-range model like the Jogger. But for everyday urban carry, 5 feet handles the most common scenarios.
How do I know when to refill it?
First, never test your defensive pepper spray by firing it. If you want to practice, buy a separate practice/inert trainer. That said, you should replace the cartridge every 3-4 years regardless of whether you’ve used it, because the propellant loses pressure over time. Check the manufacture date on the bottom. If you do use it in a defensive situation, obviously replace it immediately. The refill cartridge is available separately and takes about 30 seconds to swap out.
Can I take this through airport security?
No. TSA prohibits pepper spray in carry-on luggage, and most airlines restrict it in checked bags too, though some allow it with specific size limits (usually 4 oz or less) if it has a safety mechanism. Check with your specific airline before traveling. The Keyguard’s 0.14 oz size is well under most limits, but airline policies vary. Many people just buy a new unit at their destination rather than dealing with the hassle. In any case, never try to sneak it through airport security – that’s a federal offense and you’ll definitely lose your spray.
