If you want an added level of security for your apartment or dorm, or travel frequently and stay in hotels and Airbnbs, a portable door lock is a worthwhile investment. These ingenious temporary locks are designed to be deployed from inside the room to prevent unwanted guests from entering — even if they have a key.

There are several styles of portable locks that you can buy, and they vary in terms of size, door compatibility, and installation method. And luckily, the majority of options are very affordable, priced at about $25 or less. Some are compact enough to stash in your backpack or rolling suitcase, making them ideal for travel, while others are more heavy-duty and designed for commercial applications. Plus, there are options for almost every type of door, including hinged and sliding doors, as well as both inward- and outward-swinging configurations. Read on for our recommendations, plus essentials to consider before shopping.

Best Portable Door Locks

What to Consider

There are several types of portable door locks available today, and you’ll need to select the best option for your application. If you’re traveling, door strike locks are small and lightweight, making them easy to pack. Door stops or braces are another option for regular hinged doors, though they tend to be bigger, and some even have a built-in alarm that sounds if someone tries to open the door. For sliding doors, you’ll likely need a security bar, which are often too big to comfortably fit in a suitcase.

When buying a portable door lock, it’s important to ensure the product you select is compatible with your door. Some locks only work if the door has a specific type of door strike or gap of a certain size, so if possible, you’ll want to double-check these measurements before you buy.
