Feeling safe when you’re at home or traveling can sometimes be difficult. Whether it’s through installing a smart lock in your home, keeping pepper spray readily available or doing a double-check for spy cameras in your rental — feeling secure anywhere you go is important. For those who live in rental properties, knowing that landlords or former tenants could have easy access to your home can create some unease. When staying in rentals or hotels, guests may feel uncomfortable knowing that employees and owners could enter their room at any time. And for those who live with nosy roommates, being able to lock the bedroom door can provide an added feeling of security and help solve arguments over privacy once and for all. That’s why a portable door lock is a great item that can help users feel safe when at home or traveling.
It’s important to note that portable door locks should only be used in legally approved manners. Ensure all the members of your home know how to remove the lock in case of a fire and always use precautions when using a portable door lock.
What Do Portable Door Locks Do?
Portable door locks act as a reinforcement for locking doors and can also be used on doors that don’t have locks, like interior doors. We’ve included styles of portable door locks that can be used from the inside of the home or room as well as portable door locks that can be used on the outside. These locks provide an additional level of security and can act as a deterrent for intruders — whether that’s a busybody roommate or an unscrupulous landlord.
1. The Original Portable Door Lock by Addalock
BEST OVERALL
Feel safe even when traveling by using the Original Portable Door Lock by Addalock. Installation takes only a few seconds and provides an added level of security in any hotel room or rental. Metal claws are inserted into the strike plate when the door is open. Once the door is closed, the Addalock is installed, making it impossible for those with a key to open the door from the outside. Designed to be used on the inside of a door to slow intruders and keep out people with a key, the Addalock is ideal for use in hotels, college dorms or home rentals when strangers may have access to your door.
Pros: The Addalock comes with a storage pouch for protection when the lock is not in use.
Cons: The Addalock may not work on doors with large deadbolts.

2. Travelers Security Lock
CONTENDER
The Travelers Safety Lock is the most secure option on the list, but also the most expensive. It’s constructed from aircraft-grade aluminum that will stand up to serious pressure. This portable door lock can be installed on right- or left-facing doors and is incredibly easy to install. By redistributing any force applied to the door to the lock and doorframe, this lock provides serious protection from intruders. An included carrying case makes it easy to travel with.
Pros: Heavy-duty materials provide reliable security while traveling. Easy to install on virtually any door. Protects against keys and forced entry.
Cons: More expensive than other travel locks. Users with mobility issues may have trouble installing this lock.

3. Calslock Portable Door Lock for Travel
QUALITY PICK
The Calslock Portable Door Lock for Travel provides peace of mind when home or traveling. The small lock is the size of two pens but provides a sturdy second lock over a deadbolt. The Calslock can be used by hooking the lock into the strike plate and then squeezing and pulling back the slide bar when the door is open. Once the door is closed, users simply squeeze the slide bar and push it against the door. The Calslock works best on doors with a small gap between the frame and the door. Like the Addalock, the Carslock is ideal for use in places where multiple people may have access to your door, including hotels, dorms and rentals.
Pros: The Calslock will provide resistance against intruders pushing in on the door and will create a loud noise that can alert sleeping residents.
Cons: The Calslock only works on doors that swing inwards. The serrated edge makes this lock unsafe for homes where small children can reach the door handle.

4. Prime-Line Door Knob Lock-Out Device
HONORABLE MENTION
Help prevent others from accessing the lock on your doorknob with the Prime-Line Door Knob Lock-Out Device. The lock fits over a round doorknob and uses a key to prevent the turning of the knob and access to the keyhole. The cylinder inside the lock is held in place with an O-ring and can be removed when the device is unlocked and open. The Prime-Line can be installed in seconds and is made with a durable, diecast construction.
Pros: Customers can use the Prime-Line to prevent prying landlords from entering their homes without permission. Because the lock fits over the doorknob, the renter isn’t changing the locks, which is against many rental policies.
Cons: The Prime-Line can only be used on round doorknobs.
