You like the idea of ditching house keys and upgrading to a modern smart lock, but you’re worried about safety. Are keypad door locks really safer than the keyed locks they replace? The quick response is yes. But before installing one with your Sacramento smart home, there are some things you should know.

Why upgrading to a smart lock makes sense for your Sacramento home

The inherent problem with traditional locks is the requirement of a key. Keys are frequently lost and simple to copy, which spells trouble if they fall into the wrong hands. On top of that, older door locks are simpler to force, pick, and bump. Modern smart locks eliminate the need for a key entirely. The options that provide a backup keyed system typically use a different type of cylinder, so they can’t be circumvented by traditional methods.

What are the risks of keypad door locks?

While they’re generally safer than traditional locking systems, keypad door locks do have some risks, including the following:

  • Unauthorized code use: Codes must be kept secure. It’s also a good idea to update them often and avoid obvious codes like “1234.” If you have to give somebody one-time access, you can configure a code and then delete it once it’s no longer needed.

  • Hacking: System breaches are always a risk to electronic devices connected to your smart home. Offset the risk by regularly updating apps, firmware, and passwords. Integrate two-factor identification if possible.

  • Technical problems: A WiFi disconnection, software bug, or battery failure can lead to problems. As a general rule, essential local features like keypad entry still work even when your WiFi is down, but you may lose smartphone app functionality. Models with backup keyed systems can provide you with another way in.

Do smart locks still function during a power outage?

Yes, your smart lock should still work during an outage as it is powered by batteries, not your home electricity. You may still use the keypad, Bluetooth, or biometric scanner, based on what your system supports.

Why Vivint smart locks are an excellent choice for your home

Vivint’s smart locks work smoothly with other equipment within your smart home ecosystem. You can make a rule to turn the lights on automatically whenever the door is unlocked, or create a full-fledged scene with several automations. For instance, you might dim lights, lock your door, arm your system, and even adjust your thermostat all at once when you go to bed. And you know the best part? Your locks and all your smart home equipment is totally accessible in the palm of your hand with the Vivint app.

You’ll always know who’s exiting and entering as Vivint systems keep track of smart lock codes. You can also assign as many as 50 distinct access codes.
