Are keypad door locks safe?

You are drawn to the idea of getting rid of your old house keys and switching to a modern smart locking system, but safety is still a concern. Are keypad door locks really safer than their time-honored counterparts? The easy answer is yes. But before integrating one into your Modesto smart home, there are a few things you should consider.

Why upgrading to a smart lock makes sense for your Modesto home

The biggest downside of 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. In addition, older locks are more vulnerable to bumping, picking, and forcing. Modern smart locks do away with keys entirely. The models that offer a backup keyed lock typically use a more secure style of cylinder, making them resistant to traditional break-in methods.

What are the risks of keypad door locks?

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

  • Unauthorized code use: Codes must be kept secure. It’s also a good idea to update them often and avoid easy-to-guess codes like “1234.” If you want to give someone one-time-only access, you can configure a code and then eliminate it once it’s no longer needed.

  • Hacking: Cyber intrusions are always a risk to electronic devices linked to your smart home. Reduce the risk by regularly updating apps, firmware, and passwords. Incorporate two-factor identification whenever you can.

  • Technical glitches: Issues can arise due to a software bug, 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 work during power failures?

Yes, your smart lock should still operate when power is lost as it runs on battery power, not your home electricity. You’ll still be able to use the keypad, fingerprint scanner, or Bluetooth, based on what your system supports.

Why select Vivint smart locks for your Modesto home?

Vivint’s smart locks work reliably with other devices within your smart home ecosystem. You can turn the lights on when the door is opened, or create a complete scene with multiple automations.

Your locks and all your smart home components are fully accessible in the palm of your hand with the Vivint app.
