You are drawn to the idea of getting rid of traditional house keys and switching to a modern smart lock, but safety is still a concern. Are keypad door locks really safer than their time-honored counterparts? The quick answer is yes. But before integrating one into your South Fulton smart home, there are several things you should think about.

Why smart locks are the best choice for your South Fulton home

The inherent problem with traditional locks is the requirement of a key. Keys are frequently misplaced and simple to copy, which leads to disaster if they fall into the wrong hands. In addition, older door locks are easier to force, pick, and bump. Modern smart locks remove the need for a key entirely. The options that have a backup keyed system usually use a different kind of cylinder, so they can’t be bypassed by traditional methods.

Are there any risks with keypad door locks?

Although typically safer than older locking systems, keypad door locks do carry some risks, like the following:

  • Unauthorized code usage: Codes need to be kept secure. It’s also a good idea to change them regularly and never use predictable codes like “1234.” If you want to give a person single-time access, you can set a code and then remove it once it’s served its purpose.

  • Hacking: Cyber intrusions are always a risk to electronic devices bridged to your smart home. Offset the risk by updating firmware, apps, and passwords frequently. Integrate two-factor identification whenever you can.

  • Technical issues: A battery failure, WiFi disconnection, or software bug can lead to problems. Generally speaking, vital local features like the keypad still work even when your WiFi is not available, but you might lose app functionality. Models with backup keyed systems can offer another way in.

Do smart locks still work during a power outage?

Yes, your smart lock should still function when power is lost as it is powered by batteries, not your home’s electricity. You may still use the keypad, fingerprint scanner, or Bluetooth, based on what your system supports.

Why choose Vivint smart locks for your South Fulton home?

Vivint’s smart locks work reliably with other components within your smart home environment. You can set a rule to switch the lights on when the door is opened, or establish a whole-home scene with many automations. To illustrate, you can turn lights off, lock your door, arm your system, and even lower your thermostat all at once when you go to bed. The best part is that your locks and all your smart home equipment is fully accessible from your phone in the Vivint app.

You’ll always be aware of who’s coming and going as Vivint systems monitor the use of smart lock codes. You can also assign up to 50 unique access codes.
