Are keypad door locks safe?

You like the idea of eliminating your old house keys and switching to a modern smart lock, but safety is still a worry. Are keypad door locks really safer than the old locks they replace? The quick reply is yes. But before integrating one into your Phoenix smart home, there are some things you should think about.

Why smart locks are the right option for your Phoenix home

The biggest downside of traditional locks is the requirement of a key. Keys are often misplaced and simple to copy, which spells trouble if they end up in the wrong hands. In addition, older door locks are easier to pick, bump, and force. Modern smart locks remove the need for a key altogether. The options that have a backup keyed system usually use a different kind of cylinder, so they can’t be circumvented by traditional methods.

Are there any concerns with keypad door locks?

Although generally safer than older locking systems, keypad door locks do come with some risks, including the following:

  • Unauthorized code use: Codes have to be kept secure. It’s also wise to update them often and steer clear of obvious 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 no longer needed.

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

  • Technical glitches: A battery failure, WiFi disconnection, or software bug can create issues. However, vital local features like a PIN code still work even if your WiFi is not available, but you may lose access to the smartphone app. Smart options with backup keyed locks can offer another way in.

Do smart locks still operate during power outages?

Yes, your smart lock should still operate when power is lost as it gets power from batteries, not your home electricity. You can still use the keypad, Bluetooth, or fingerprint scanner, according to what your system supports.
