Are keypad door locks safe?

You like the idea of getting rid of your old house keys and upgrading to a modern smart lock, but safety is still a worry. Are keypad door locks truly safer than the old locks they’re replacing? The easy answer is yes. But before integrating one into your Greenville smart home, there are some things you should consider.

Why smart locks are the right choice for your Greenville home

The inherent problem with traditional locks is the need for a key. Keys are often misplaced and simple to copy, which leads to disaster if they end up with the wrong person. On top of that, older door locks are more vulnerable to bumping, picking, and forcing. Modern smart locks do away with keys altogether. The ones that provide a backup keyed system typically use a more secure type of cylinder, so they can’t be bypassed by traditional methods.

Are there any concerns with keypad door locks?

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

  • Unauthorized code usage: Codes must be kept confidential. It’s also smart to update them regularly and never use easy-to-guess codes like “1234.” If you have to give somebody one-time access, you can configure a code and then delete it once it’s been used.

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

  • Technical issues: A battery failure, WiFi disconnection, or software bug can create issues. Generally speaking, essential local features like a PIN code still work even when your WiFi is down, but you might lose smartphone app functionality. Smart locks with backup keyed locks can offer another way in.

Do smart locks still operate during a power outage?

Yes, your smart lock should still work during a blackout as it is powered by batteries, not your home electricity. You may still use the keypad, fingerprint scanner, or Bluetooth, depending on what your system offers.

Why Vivint smart locks are an excellent choice for your home

Vivint’s smart locks work reliably with other components in your smart home. You can make a rule to switch the lights on automatically when the door is opened, or establish a full-fledged scene with many automations. To illustrate, you might arm your system, turn lights off, fasten your door, and even change your thermostat simultaneously when you head to bed. And you know the best part? Your locks and all your smart home devices are completely accessible from the convenience of the Vivint app.

You’ll always know who’s coming and going as Vivint systems track smart lock codes. You can also assign as many as 50 unique access codes.
