Portable Door Locks for Hotels and Rentals
The Addalock Original is our overall pick because it fits almost any inward opening door in seconds and packs flat. The DoorJammer Portable Lock resists far more force for longer stays, and the Wedge-It Ultimate Door Stop is the simplest thing to keep in a bag.
For hotel rooms and short term rentals the Addalock Original is the easiest portable lock to live with, while the DoorJammer Portable Lock resists more force and the Wedge-It Ultimate Door Stop is the fallback that fits in a jacket pocket.
Choosing one is harder than it looks because devices split into strike plate locks, floor jammers and door bars, and each depends on details like whether the door opens inward and what the floor is made of. We compared install methods, published force figures and what owners report about awkward doors to rank the seven below.
The best picks, ranked

Addalock Original Portable Door Lock
A two piece steel device that slots into the strike plate hole and blocks the latch with a red clasp, taking about five seconds to fit. It works on almost any inward opening door with a standard latch, regardless of floor surface. Owners report it is the one item they now pack for every hotel stay.
Pros
- Works regardless of floor surface or carpet
- Extremely fast to fit and remove
- Small and light enough to always carry
Cons
- Needs an accessible strike plate hole
- Will not work on outward opening doors

DoorJammer Portable Door Lock
A floor braced jammer that wedges under the door and screws down to increase pressure, converting any push against the door into downward force on the floor. It holds against considerably more force than latch style devices. Owners report it works best on hard floors and shorter pile carpet.
Pros
- Resists far more force than latch style locks
- Works on doors without an accessible strike plate
- No installation marks left behind
Cons
- Needs a gap under the door to fit
- Less effective on thick or deep pile carpet

Master Lock 265DCCSEN Door Security Bar
A telescoping steel bar that braces from the door handle or the door face down to the floor, adjusting across a wide length range. It also fits sliding patio doors laid in the track. Owners report it is the most reassuring option for a home or a long stay, though it is far too bulky to travel with.
Pros
- Very strong bracing for a home entry door
- Doubles as a sliding door track bar
- Rubber foot grips without marking floors
Cons
- Far too bulky for travel
- Needs floor space clear in front of the door

Calslock Portable Door Lock
A single piece steel bracket that hooks into the strike plate and blocks the door from opening even if someone has a key. The one piece design means there is no clasp to lose. It handles connecting hotel room doors and internal doors that latch style devices sometimes struggle with.
Pros
- One piece so there is nothing to misplace
- Works on connecting and internal doors
- Steel construction resists bending
Cons
- Bulkier in the strike plate than slimmer designs
- Some doors have too little strike plate depth

BuddyBar Door Jammer
A heavy solid steel bar that braces from under the door handle to the floor, weighing several pounds and built for a permanent spot behind an entry door. It resists a great deal of force but is not remotely portable. A sensible choice for a front door, a home office or a bedroom.
Pros
- Among the strongest options compared here
- No moving parts to fail or loosen
- Padded foot protects flooring
Cons
- Too heavy and long to travel with
- Fixed length limits which doors it suits

SABRE HS-DSA Door Stop Security Alarm
A wedge door stop with a pressure sensitive alarm that sounds loudly when the door pushes against it. It combines a physical barrier with an alert, which matters if you are asleep. Owners report the alarm is loud enough to wake a floor of a hotel, which is exactly the point.
Pros
- Alerts you rather than relying on the barrier alone
- Very loud alarm draws attention immediately
- Works on any inward opening door with floor grip
Cons
- Physical resistance is modest on slick floors
- Needs a battery you have to remember to check

Wedge-It Ultimate Door Stop
A moulded polymer wedge that works in three orientations, holding a door closed, holding it open or hanging over the top of the door. It weighs almost nothing and costs very little, which makes it easy to keep one in every bag. Owners report it grips well on hard floors and poorly on thick carpet.
Pros
- Almost weightless so it goes everywhere
- Three usable orientations from one shape
- Nothing to break or run out of battery
Cons
- Limited resistance to a determined push
- Poor grip on deep pile carpet
What to look for
Know which door direction you have Almost every portable door lock assumes the door opens inward toward you, because that is what lets a floor wedge or a strike plate block do its job. Outward opening doors, which are common in some apartments and on fire exits, defeat most of these devices entirely. Check which way the door swings before packing, and for outward opening doors look at devices that clamp the hinge side or simply rely on the existing deadbolt.
Strike plate locks versus floor jammers Strike plate devices such as the Addalock and Calslock block the latch itself, so they work on any floor surface and take seconds. Floor jammers such as the DoorJammer resist far more force but depend on floor friction and on there being a gap under the door. Deep pile carpet ruins wedge grip, and a door sitting flush to the floor leaves no room for a jammer, so the two categories fail in opposite situations.
Think about the failure mode, not just the strength A device that resists a shoulder charge is useful, but so is one that wakes you up. Alarm wedges make noise the moment pressure is applied, which buys reaction time even if the barrier itself yields. Many travellers carry a strike plate lock for the physical block and an alarm wedge for the alert, since together they cover both problems and still weigh very little.
Check that nothing damages the property Portable locks are popular precisely because they leave no marks and need no tools, which keeps them acceptable in hotels and short term rentals. Anything requiring screws, adhesive or drilling is a different category and needs the owner’s permission. Also remember that blocking a door completely can conflict with fire safety expectations, so use devices you can release quickly from the inside.

Good to know
Are portable door locks allowed in hotels?
They are generally fine because they cause no damage and leave no trace, and they are widely sold for exactly this purpose. Staff may need access in an emergency, so use a device you can remove instantly from inside, and do not leave one engaged when you are out of the room.
Do these work on outward opening doors?
Most do not. Strike plate locks and floor wedges both rely on the door swinging inward. For an outward opening door, your options are limited to hinge side clamps, portable alarms, and making full use of the existing deadbolt and chain.
Which type is strongest?
Floor braced bars such as the BuddyBar and the Master Lock 265DCCSEN resist the most force because they transfer the load into the floor across a long lever. Among genuinely portable options, screw down jammers like the DoorJammer hold better than latch blocks, which in turn hold better than simple wedges.
Will a door wedge work on carpet?
It depends on the pile. Low pile commercial carpet, which is what most hotels use, works reasonably well. Thick residential carpet compresses under the wedge and lets it slide, and very smooth polished floors can also be slippery. Strike plate locks avoid the issue entirely.
Can I take these through airport security?
Portable door locks are small polymer and steel items with no blades or sharp points and are routinely carried in hand luggage. Rules vary by country and by screener discretion, so if you are carrying a heavier steel bar it is safer in checked luggage.
Do I still need to use the hotel deadbolt?
Yes. A portable lock is a second layer, not a replacement. Use the deadbolt and swing bar as normal, then add the portable device. Layered barriers take longer to defeat and each one adds noise, which is itself a deterrent.
What about connecting doors between rooms?
Connecting doors are worth securing because they sometimes have simpler hardware than the main entry. Strike plate locks work well here, and the Calslock in particular is designed with these doors in mind. Check the door is actually latched before fitting anything.
How quickly can I get out in an emergency?
This matters more than raw strength. Strike plate locks release in a second or two, wedges kick free, and screw down jammers take a few turns. Practise removing whichever device you buy once, in daylight, so you are not working it out for the first time in the dark.
The verdict
For travel, the Addalock Original earns its place in the bag because it fits nearly any hotel door in seconds and weighs almost nothing. Longer stays and rentals with awkward door hardware are better served by the DoorJammer Portable Lock, and adding a SABRE HS-DSA alarm wedge covers the case where you are asleep and need warning rather than resistance.
