Kervalon® 2-in-1 Portable Door Lock & 90dB Alarm

Kervalon® combines a heavy-duty portable door lock with a built-in 90dB security alarm, giving you both physical resistance and an audible alert. If someone attempts to force the door open, the alarm immediately sounds to warn you and deter intrusion.

The powerful 90dB alarm is loud enough to wake you up and alert nearby people. It adds an extra layer of defense, especially when you’re sleeping, traveling alone, or staying in unfamiliar places.

Simply insert and secure — no drilling, no screws, no damage to doors. It works within seconds, making it ideal for renters, hotel guests, and dorm residents who need temporary yet reliable security.

Compact and lightweight, this portable security device fits easily into your bag or suitcase—so you can stay protected wherever you go. Ideal for travelers, renters, students, seniors living alone at home, or anyone who values added privacy and peace of mind. Reliable protection that keeps you secure in hotels, apartments, dorms, offices, or your own home.

Lightweight and small enough to fit inside your bag or suitcase, Playtrixlab® goes wherever you go. Whether it’s a hotel, Airbnb, apartment, or office, you can carry peace of mind with you.

Crafted with reinforced metal components, this lock is designed to withstand pressure and prevent unauthorized entry attempts while remaining easy for you to remove when needed.

Kervalon® ensures complete security with a powerful alarm, dual protection, and robust design — unlike other portable door locks that rely on flimsy components or lack alarms entirely.
