How to Use a Portable Door Lock: Extra Security for Travel or Home
Published Date: Aug 19, 2025
Are you looking for a simple way to make your space safer, whether you’re traveling or just want more protection at home? A portable door lock is a smart answer. These compact tools are designed to add an extra layer of security when traditional locks aren’t enough — or when there’s no lock at all. However, not all travel door locks work the same way. This guide from Sure Lock & Key walks you through the most common types and how to use them properly, depending on your door type and situation.
Top Places to Use a Portable Door Lock
A travel door lock is small enough to pack but strong enough to add extra privacy. It’s ideal when the standard lock just doesn’t feel like enough. Here are a few situations where these locks really come in handy:
- Hotel rooms — Add a personal layer of safety beyond the key card or standard latch.
- Rental homes — When staying at an Airbnb or similar, a portable lock can help you secure your Airbnb home and rest easier.
- Dorm rooms — Students can use these locks for extra privacy in shared spaces.
- Home use — Even at home, they’re useful for adding privacy to rooms like offices, basements, or guest areas.
Types of Portable Door Locks and Their Best Uses
1. Addalock and Similar Insert-Style Locks
One of the most popular travel locks is Addalock, designed for inward-opening doors with a visible strike plate. If you’re searching for how to use Addalock, here’s what to do:
- Open the door slightly and insert the metal “claw” part into the strike plate (the hole where the latch enters the frame).
- Close the door gently on the claw so it stays in place.
- Slide the red handle (locking arm) into the groove on the claw.
This locks the door from the inside and can’t be removed without reopening it. It’s perfect for hotels, dorms, or rooms without deadbolts.
2. Door Jammer or Under-Door Wedge Locks
These wedge-style tools slide under the bottom of the door. Once pressure is applied (like someone trying to open the door from the outside), the wedge tightens, stopping it from opening. They’re ideal for tile or hardwood floors and lightweight interior doors. Some models also use adjustable foot levers for extra grip. Great for travelers who want quick setup and removal.
3. Chain-Style Portable Door Locks
Less common but useful in apartments, these portable chains anchor to the door frame with an adhesive or clamp, then hook onto the knob. While not as strong as Addalock, they’re handy when other options don’t fit.
Choosing the Right Lock for the Situation:
- Inward-opening doors? Go with Addalock or similar insert types.
- Smooth floors and light doors? Try a wedge-style lock.
- Staying somewhere temporarily and can’t install anything? Travel chain locks may work best.
Want a More Permanent Solution?
You now know how to use portable door locks, but remember that they offer temporary protection and aren’t a full replacement for strong home security. If you find yourself constantly relying on a travel door lock, it might be time to consider an upgrade, so you can feel truly secure without always needing a temporary tool.
