What is a smart lock and how does it work?

Smart locks are an increasingly common sight around neighborhoods. These gadgets bring some modern amenities to your front door, letting you eschew your traditional key to operate your deadbolt with a password, fingerprint, or Bluetooth. If you’re curious to learn more about smart locks before adding one to your home, here’s everything you could want to know.

What is a smart lock?

At its most basic, a smart lock is an electronic lock that connects to your home and lets you open your door without needing a traditional key.

This can be done using a keypad, smartphone app, and sometimes a fingerprint scanner. There are a variety of reasons for adding one to your home, but one of the main reasons why homeowners prefer smart locks over traditional locks is their versatility — letting them give temporary passwords to visitors, removing the need to make copies of keys for family members, and providing peace of mind when away from home. If you’re not ready for an all-digital door, you’ll be glad to know that many smart locks include a traditional keyhole in their design.

This means you’ll benefit from all the smart home features while still being able to access your home with a key (a great option if the lock’s batteries die). You’ll also be happy to know that smart locks are just as secure as traditional locks and you won’t have to trade safety for convenience when adding one to your front door. Some obscure models might be susceptible to hacking, although models from trusted brands are typically ironclad.

Features offered by a smart lock

Smart locks bring a myriad of features to the table.

These vary based on the exact model you’ve purchased, with premium locks typically offering more than their budget counterparts. Here’s a quick look at some of the tasks smart locks can perform.

  • Unlock with keypad: Most smart locks include a keypad. This allows you to simply type in a password to unlock or lock the door — removing the need for a standard key.
  • Unlock with a smartphone app: If you’ve installed a companion smartphone app when setting up your smart lock, you’ll get a bevy of additional features.

    One such feature is the ability to open your door remotely using your smartphone app. Conversely, you can use the app to ensure your door is locked when away from home.

  • Set temporary password: Using your home as a short-term rental? Smart locks make it easy to secure your home for each new visitor by allowing for temporary passwords.

    These typically run alongside your permanent password, letting you quickly swap out codes whenever a new visitor books a room without deleting your primary password.

  • Sync with your smart home: Smart home products come in all shapes and sizes, and smart locks often fit right into your existing ecosystem. This allows you to set a variety of parameters after unlocking or locking your door, such as turning off lights or changing the temperature of your home. Some smart locks can even connect to your home security system.
  • Auto-lock functionality: There’s nothing worse than getting on the road and not remembering if you’ve locked your door.

    Opting for a premium smart lock negates this problem entirely, as many models let you enable an auto-lock function that’ll deadbolt your door after a few minutes of inactivity.

  • Send smartphone alerts: Some smart locks let you enable push notifications to receive alerts when your door is locked or unlocked. This is especially useful if you’re having a dog sitter swing by your home while on vacation, letting you know when they arrive and ensuring the door locks when they leave.
