What is a smart lock for a door?

A smart lock for a door is a type of lock that takes advantage of innovations like the Internet of Things to enable powerful features that aren’t available on an old-school lock.

Smart door lock features include:

  • Multiple credentials. You can choose between multiple ways to open the door. You can choose between PINs, card or fob readers, or even fingerprint scanners — and many locks support multiple options at once.
  • Remote unlocking. These days, you don’t even have to carry around a physical credential or memorize a PIN – using a keyless entry door lock is as easy as a few swipes on your phone.
  • Easier administration. If you’re a property manager, you can easily set or remove users instead of fumbling around with manual records.
  • Higher security. This feature ties into easier administration — you’re less likely to leave a security flaw by leaving an old resident’s password in your system. Plus, you can easily shuffle around PIN codes or issue new keys or fobs if you suspect a security breach.


Can you put a smart lock on any door?

Yes, you can put a smart lock on any door. Whether you’re interested in placing a smart lock on a hinged door or a sliding door, there’s a smart lock on the market that can fit your needs.

You can also put a smart lock on a door that already has an analog lock, or you can install that lock on a door without any previous lock.


What is the difference between a smart lock and an electronic lock?

A smart lock has more features than an electronic lock.

Electronic locks only use wireless tech to read credentials and verify residents’ identities. In contrast, smart locks use wireless technology to connect to other devices to enable features like remote unlocking.

How do smart locks for doors work?

Smart locks for doors work by connecting to other pieces of technology, like your smartphone or a router that connects to the internet.

Smart locks for doors have these components:

  • Credential reader. Smart locks use wireless receivers to communicate with credentials. A keyless entry door lock with app connects with a smartphone to receive its credential. Other locks might scan a fob or come with a keypad that accepts a PIN code.
  • Access control panel. After the reader intakes the credential data, the lock forwards it to an access panel that actually verifies the data. The access panel might be located inside the lock, or it might be a larger access panel somewhere on the property that controls several locks at once.
  • Locking mechanism. These are the physical components that engage and disengage at the direction of the access panel.


How do you turn an existing door lock into a smart lock?

You turn an existing door into a smart lock by removing the analog face of your lock and installing the smart lock. This way, you can use your existing deadbolt.

Otherwise, you can remove your old lock entirely and install a smart door lock with a handle, that uses its own deadbolt.
