You like the idea of eliminating traditional house keys and switching to a modern smart locking system, but you have concerns about safety. Are keypad door locks actually safer than their old-school counterparts? The easy reply is yes. But before adding one to your Tempe smart home, there are several things you should consider.

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

The main issue with traditional locks is the need for a key. Keys are frequently lost and easy to copy, which spells trouble if they fall to the wrong person. In addition, older door locks are more vulnerable to bumping, forcing, and picking. Modern smart locks eliminate the need for a key completely. The options that provide a backup keyed system usually use a more secure style of cylinder, so they can’t be bypassed by traditional methods.

Are there any concerns with keypad door locks?

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

  • Unauthorized code use: Codes have to be kept secure. It’s also wise to update them often and never use predictable codes like “1234.” If you have to give a person one-time access, you can set a code and then remove it once it’s served its purpose.

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

  • Technical issues: Issues can arise due to a software bug, WiFi drop, or battery failure. As a general rule, vital local features like a PIN code still work even when your WiFi is not available, but you could lose access to the smartphone app. Smart locks 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 operate during a blackout as it runs on battery power, not your wired electricity. You can still use the keypad, Bluetooth, or fingerprint scanner, according to what your system uses.

Why Vivint smart locks are an excellent choice for your home

Vivint’s smart locks work seamlessly with other components in your smart home. You can switch the lights on automatically whenever the door is unlocked, or configure a whole-home scene with multiple automations. For example, you can turn lights off, lock your door, arm your system, and even change your thermostat all at once when you head to bed. And you know what else? Your locks and all your smart home devices are fully accessible in the palm of your hand with the Vivint app.

You’ll always get insights into who’s entering and exiting as Vivint systems monitor the use of smart lock codes. You can also create as many as 50 distinct access codes.
