The best portable door lock for travel is the Addalock. It hooks into the door’s existing strike-plate hole and braces the door from the inside, so it holds even if someone has a key or slips the latch, it packs into a purse, and it runs under $20. Portable locks work on in-swinging doors only, which covers almost every hotel, Airbnb, and home entry door.
A portable door lock (also called a travel lock) is a tool-free device that adds a lock, or strengthens a weak one, on a door you do not control: a hotel room, an Airbnb, a dorm, or any door where someone else might have a key. We tested the main types the way a locksmith looks at any lock and scored each from 1 to 5.
How we scored the locks
Four things separate a good portable lock from a useless one:
- Effectiveness: does it add real security over the door’s own lock, and does it brace at the strongest point (the center of the door beats the top or bottom)?
- Versatility: does it fit different door sizes and configurations, and does it work on the floor type in the room?
- Ease of use: tool-free install and removal, and small enough to pack without losing parts.
- Cost: a few dollars to around $30 for this category.
How results
| Product | Type | Effectiveness | Ease | Cost |
|---|---|---|---|---|
| Addalock (winner) – See on Amazon | Strike-claw brace | 5/5 | 4/5 | 5/5 |
| Adjustable Portable Door Lock (runner-up) – See on Amazon | Strike-claw brace | 4/5 | 4.5/5 | 5/5 |
| Door jammer bar | Floor brace bar | 4/5* | 3/5 | 4/5 |
| Door stopper wedge | Friction wedge | 1.5/5 | 5/5 | 5/5 |
*The jammer bar only earns a 4 when installed correctly on a hard floor; it slips on carpet and linoleum.
The best portable door lock: the Addalock
The Addalock uses the latch hole already in the door frame. Metal claws seat into that strike-plate opening, and a coated metal piece hangs into the room as a brace. When the door is pushed, it hits the brace, which pulls against the strike plate and stops the door. Because it braces the frame, it holds even when the latch is retracted with a key, keycard, or bypass tool, which is exactly the failure point of the lock already on the door. The wedge has claws on both sides, one for commercial strikes and one for standard house strikes, so it works regardless of lock type. It is effectively as strong as a residential deadbolt, packs flat, keeps its parts on a chain, and costs under $20. Check the current price on Amazon.

How to set one up
- Confirm the door swings inward. Portable locks only work on in-swinging doors, which is most hotel, Airbnb, and entry doors.
- Seat the claws into the strike-plate hole on the frame, or set the jammer/brace against the door and floor.
- Hang or position the brace so it blocks the door from opening.
- Test it by pushing the door before you rely on it overnight.
- To leave, lift the brace and pull the claws out. No tools, nothing left behind.
Runner-up: the Penmama
The Penmama works on the same strike-plate principle as the Addalock and is easy to use, scoring 4.5 on ease. It is a touch less versatile across door types, which is the only reason it lands second. A great backup or second-room option.
The main advantage is that it’s adjustable to ensure it fits tightly on and door, but that is also what makes it a bit more difficult to use.
Door jammer bars
A jammer bar braces from the door down to the floor. Installed correctly on a hard floor it is effective, but it comes in multiple parts, takes longer to set, and slips on carpet or slick linoleum, so it scores lower on ease and is floor-dependent.
Door stopper wedges: skip them
A rubber wedge under the door adds friction and nothing more. It is the cheapest and easiest, but at 1.5 of 5 for effectiveness it is a light deterrent, not a lock. Fine as an extra layer, not as your security.
When a travel lock is worth packing
They earn their spot when you cannot trust the lock on the door: a hotel or Airbnb where staff or past guests may have keys or codes, a rental room, a dorm, or a connecting-room door. They are also the answer for a door with no working lock at all. For a door you own and want truly secured, install real hardware, see lock installation, and for glass or patio doors read how to secure French doors.
What portable door locks cannot do
They only work on in-swinging doors, so an out-swinging door is out. A determined kick can still force some of them, and bar or wedge types slip on carpet and slick floors. Treat a portable lock as a strong travel layer and an early warning, not a permanent solution. Traveling with a padlock too? See our best combination padlock guide.
