These 6 Security Door Locks Instantly Enhance Security — Starting at $16
There are a lot of smart home devices such as cameras and video doorbells that can help keep your home safe. They’re a good deterrent, but the catch is that these devices cannot stop someone from entering your home. To prevent a forced entry attempt, it’s a good idea to invest in physical security that makes a break-in more difficult. If your front door isn’t secure enough, a security door lock is a great option.
Deadbolts go a long way to keeping your home safe, but they’re not perfect. One of the significant limitations of a deadbolt isn’t the lock itself but what it’s attached to. If the strike plate on your door is small or not very well secured, it could become detached from the doorframe with enough force. The strike plate is the metal piece that connects to the door frame. One way to improve your front door’s security is by replacing your old strike plate with something more extensive and sturdier.

In addition to securing your front door with improved hardware, you can invest in a security door lock. These are auxiliary locks that attach to the inside of your door. They’re easy to open from the inside, but they add extra safety to your home.
Some security door locks and portable travel locks can also be used on interior doors that don’t have locks. Suppose you share an apartment with multiple people or want to ensure a little extra privacy. In that case, a security door lock can be used on interior doors without replacing your hardware or needing a keyed lock. These can also be useful in keeping children safe from entering rooms they shouldn’t be in.
We’ve rounded up some reinforcement security locks, which we’ve assessed based on reviews, features and brand reputation. Check out some options below.
