Are keypad door locks safe?

You like the idea of ditching your old house keys and switching to a modern smart locking system, but you’re concerned about safety. Are keypad door locks actually safer than the old-school locks they’re replacing? The simple response is yes. But before installing one with your Arlington smart home, there are a few things you should know.

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

The main issue with traditional locks is the need for a key. Keys are frequently misplaced and simple to copy, which spells trouble if they end up in the wrong hands. On top of that, older locks are more vulnerable to picking, bumping, and forcing. Modern smart locks remove the need for a key altogether. The ones that offer a backup keyed lock usually use a different type of cylinder, so they can’t be bypassed by traditional methods.

What are the risks of keypad door locks?

Although typically safer than traditional locking systems, keypad door locks do carry some risks, such as the following:

  • Unauthorized code entry: Codes must be kept confidential. It’s also wise to update them regularly and never use obvious codes like “1234.” If you have to give somebody single-time access, you can set a code and then eliminate it once it’s no longer needed.

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

  • Technical issues: A software bug, battery failure, or WiFi disconnection can cause issues. However, core local features like a PIN code still work even if your WiFi is not available, but you might lose smartphone app functionality. Smart locks with backup keyed systems can offer another way in.

Do smart locks still operate during a power outage?

Yes, your smart lock should still function during a blackout as it gets power from batteries, not your home’s electricity. You can still use the keypad, fingerprint scanner, or Bluetooth, based on what your system supports.

Why pick Vivint smart locks for your Arlington home?

Vivint’s smart locks work smoothly with other devices in your smart home. You can set a rule to turn the lights on automatically whenever the door is opened, or create a complete scene with several automations. For instance, you might turn lights off, lock your door, arm your system, and even lower your thermostat simultaneously when you go to bed. The best part is that your locks and all your smart home devices are totally accessible from your phone in the Vivint app.

You’ll always be aware of 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.
