Portable Door Lock with Alarm

This lock works on most standard inward-swinging doors with a standard latch/strike plate configuration. It fits the vast majority of hotel rooms, apartments, and homes. However, some modern hotel doors with extra-wide strike plates, recessed latches, or non-standard hardware may not be compatible. We always recommend a quick test when you arrive — it takes 10 seconds. If it doesn't fit your specific door, our 30-day guarantee has you covered.

130dB is louder than a rock concert (120dB) and approaching the threshold of pain. For context: a normal conversation is 60dB, a car horn is 110dB, and a jet engine at 100 feet is 130dB. This alarm will not only wake you up — it will wake everyone on your hotel floor. That's the point. The shock and noise alone sends most intruders running immediately.

Yes. The lock and alarm function independently. You can use just the physical lock for a silent security barrier, just the alarm as a vibration detector, or both together for maximum protection. Most customers use both, but you have full flexibility.

The three levels (high, medium, low) control how easily the vibration alarm triggers. Use HIGH for quiet hotel rooms where any touch should trigger the alarm. Use MEDIUM for standard environments. Use LOW for doors that rattle from wind or AC vibration — this prevents false alarms while still detecting actual tampering.

Up to 1 year on standby from a single USB-C charge. Active alarm use draws more power, but even with frequent triggers, a single charge lasts months. Charging takes under 2 hours. We recommend charging before each major trip, though you likely won't need to.

This lock is designed for inward-swinging doors only — which covers the vast majority of hotel rooms, apartments, and residential doors. Outward-swinging doors (common in some commercial buildings or European hotels) require a different security approach. If you're unsure, check which way your door swings from the inside.

In most cases, yes — this lock works alongside your existing deadbolt for layered security. However, some hotel doors with extra-long strike plates may require you to choose one or the other. The travel lock provides a unique advantage the deadbolt doesn't: the hotel (and anyone with a master key) cannot override it from the outside.

If you travel with a partner, have multiple doors (like a suite), or want one for home and one for travel — the 2-Pack at $17.09 ($8.55 each vs. $9.99 each) is the clear value choice. Many customers order a second one after their first trip because they want coverage for both the main door and the bedroom.

A basic door stop alarm sits on the floor and relies on friction. This is a proper lock mechanism with a dual-claw strike plate that physically prevents the door from opening — plus it has a 130dB alarm with adjustable sensitivity and USB-C rechargeable battery. It's a physical barrier AND an alarm system in one device, not just a noisemaker on the floor.
