A smart lock is a type of door lock that doesn’t require only traditional key. Instead, it uses your smartphone, biometrics or a special code to open or close the lock. You can control it remotely, meaning you can lock or unlock your door from anywhere using an app on your phone. Some smart locks even let you give temporary access to guests, so they can unlock the door without you needing to be there. It’s like having a high-tech way to keep your home safe and easily manage access.
