Portable Door Lock & Alarm, Dual Protection Security Door Set for Home, Travel, Apartment, Hotel Safety

Portable door locks are made of heavy-duty steel material and strong ABS plastic, with a thick and rigid design. These door security devices offer better performance and durability, adding trusted bolt security to your door locks to prevent unauthorized entry. Doors equipped with these locks cannot be opened from the outside, even with a key or magnetic card.

The door stopper alarm features a 120dB siren, a stainless steel pressure plate, and a non-slip bottom. It offers three sensitivity levels - low, medium, and high. When the baffle is stressed while the alarm is in the "on" status, it will trigger an extremely loud 120dB alarm, scaring away intruders and helping to wake you and give you time to find help. The door stop alarm is powered by a single 9V battery (not included).

This door lock can be installed in seconds without any tools, even in emergency situations or in the dark. Simply insert the metal piece into the hole on the door jamb, align the lock core with the hole, close the door, and then place the black handle groove onto the stud on the metal sheet. Once in place, the door cannot be opened from the outside.

The door security devices have a portable, compact, and convenient design, with two holes of different sizes to ensure suitability for most hinges and inward-swinging doors. They are perfect for use in hotels, dormitories, apartments, Airbnbs, bathrooms, bedrooms, and other similar settings. These portable door locks can also be used to prevent pets from going out and to keep children from opening their doors to strangers, providing an additional layer of security for your home.

The manufacturer provides lifetime technical support to customers. If you have any questions or problems with your purchase, you can contact them directly to replace the portable door lock or receive a full refund. They offer professional services at all times, ensuring a worry-free purchasing experience.

The package includes 1x Portable Door Lock and 1x Door Stop Alarm.
