You like the idea of eliminating house keys and upgrading to a modern smart lock, but you’re worried about safety. Are keypad door locks really safer than their time-honored counterparts? The quick answer is yes. But before integrating one into your Huntsville smart home, there are a few things you should know.

Why switching to a smart lock makes sense for your Huntsville home

The main issue with traditional locks is the requirement of a key. Keys are frequently misplaced and easy to copy, which can be a real problem if they fall to the wrong person. Besides, older door locks are easier to force, pick, and bump. Modern smart locks eliminate the need for a key entirely. The options that offer a backup keyed lock typically use a more secure type of cylinder, so they can’t be bypassed by traditional methods.

What are the risks of keypad door locks?

While they’re typically safer than older locking systems, keypad door locks do carry some risks, like the following:

  • Unauthorized code usage: Codes must be kept confidential. It’s also smart to update them often and avoid predictable codes like “1234.” If you want to give somebody one-time-only access, you can configure a code and then delete it once it’s served its purpose.

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

  • Technical issues: A battery failure, WiFi disconnection, or software bug can create problems. As a general rule, essential local features like the keypad still work even when your WiFi is offline, but you may lose smartphone app functionality. Models with backup keyed locks can give you another way in.

Do smart locks still work during power failures?

Yes, your smart lock should still operate when your power goes out as it is powered by batteries, not your home electricity. You may still use the keypad, Bluetooth, or fingerprint scanner, depending on what your system uses.

Why Vivint smart locks are an excellent choice for your home

Vivint’s smart locks work smoothly with other components in your smart home. You can set a rule to turn the lights on automatically whenever the door is opened, or configure a complete scene with many automations. For example, you might turn lights off, fasten your door, arm your system, and even change your thermostat all at once when you call it a day. And you know what else? Your locks and all your smart home devices are totally accessible from the convenience of the Vivint app.

You’ll always be aware of who’s coming and going as Vivint systems keep track of smart lock codes. You can also set up to 50 unique access codes.
