I used to lie awake in unfamiliar hotel rooms wondering who else had a key. Since I started traveling with GuardLatch, that worry is gone. It sets up in seconds and finally lets me sleep through the night.

The Smarter Way To Secure Any Door
Fortress-Grade Steel Core
Reinforced high-strength metal shrugs off forceful impacts. Attempted break-ins meet solid resistance instead of an easy way in.
Made-to-Fit Versatility
Dual-sized openings adapt to nearly any standard strike plate. One lock works across apartments, dorms, and hotel rooms alike.

Family-Safe Barrier
Keeps curious kids and pets from slipping out unsupervised. It's a simple extra layer that keeps your whole household contained.
Restful Peace Of Mind
Even if a master key gets used, this backup barrier holds the door shut. Sleep easy knowing you've got a second line of defense.

Based On Real and Honest Experiences
Moving into my first dorm, I wanted extra security without upsetting my landlord. This little lock slid onto my door strike perfectly and took under a minute to install, and now I actually feel safe at night.
Honestly, I doubted a small metal lock could really stop a door from being forced. After trying GuardLatch on every door in my new apartment, I'm sold. It's solid, fits perfectly, and doesn't budge an inch.
