I used to roll my eyes at travel safety gear—until someone tried to open my hotel room door in the middle of the night. Not because of bad intentions, but because he was drunk and lost. Since then, I don’t travel without my €2 stainless steel travel door lock. It’s light, small, and it adds the peace of mind I didn’t know I needed.
Quick Guide – What You Need to Know

How to Use This Travel Door Lock
The stainless steel version from Temu is simple but effective. Here’s how I use it:
- Open the door from inside your room.
- Insert the metal plate into the strike hole of the door frame.
- Close the door. The flat plate will now be sandwiched between the door and frame.
- Loop the handle part through one of the slits and pull tight.
- Test the door by pushing it gently—it should feel blocked and resistant.
You don’t need screws, tools, or modifications. It doesn’t damage doors and it doesn’t leave a mark. Just pack it back in your bag when you leave.
Real-Life Moments It Made a Difference
In Mexico City, my Airbnb had a door that latched but didn’t actually lock. I didn’t realize it until after I’d unpacked. I used the travel door lock that night and finally got some sleep.
In a hostel in Budapest, someone mistook my room for theirs and tried to come in. The front desk gave them the wrong number. Thanks to the lock, they couldn’t open the door—just a loud thud that woke me up.
Even in places with good locks, I’ve used it when housekeeping showed up too early, or when I needed to leave my laptop charging while I was in the shower.
Best Travel Door Locks for 2025
- Temu Stainless Steel Lock (€2) – Basic but strong, fits most doors, unbeatable price.
- Addalock (~€25) – Plastic housing, easier to install, bulkier.
- AceMining Portable Lock (~€20) – Sturdy and ergonomic, good for repeated use.
- DoorJammer (~€30) – More industrial, heavier, adds downward pressure.
- Mini Alarm Wedges (~€20–25) – Not true locks, but sound an alarm if the door moves.
If you’re just getting started or traveling occasionally, the Temu version is perfect. I’ve used mine in at least 10 countries.
Why This Matters Especially for Women
I don’t use a travel door lock because I’m afraid. I use it because I want to sleep through the night without unexpected surprises. I’ve had friends walk in the wrong room. I’ve had hotel staff open the door without knocking. None of them meant harm—but that doesn’t make it okay.
This lock gives me control in situations I can’t predict. It doesn’t cost much, and once it’s in your bag, you don’t notice it—until you need it.
Final Thoughts
You don’t have to wait for a bad experience to protect yourself. A travel door lock is a cheap, practical tool that does exactly what it’s supposed to. I don’t leave home without mine. For €2, it’s one of the smartest things I’ve ever packed.
