Are keypad door locks safe?

You like the idea of getting rid of your old house keys and moving to a modern smart lock, but you’re concerned about safety. Are keypad door locks really safer than the keyed locks they’re replacing? The easy reply is yes. But before adding one to your Charleston smart home, there are a few things you should think about.

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

The biggest downside of traditional locks is the need for a key. Keys are often misplaced and simple to copy, which leads to disaster if they end up in the wrong hands. On top of that, older locks are simpler to force, pick, and bump. Modern smart locks do away with keys entirely. The ones that have 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?

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

  • Unauthorized code use: Codes must be kept secure. It’s also a good idea to change them regularly and never use obvious codes like “1234.” If you have to give a person one-time access, you can set a code and then eliminate it once it’s been used.

  • Hacking: Network breaches are always a concern for electronic devices linked to your smart home. Reduce the risk by regularly updating firmware, apps, and passwords. Use two-factor identification if possible.

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

Do smart locks still work during power outages?

Yes, your smart lock should still operate during a blackout as it runs on battery power, not your wired electricity. You may still use the keypad, Bluetooth, or fingerprint scanner, according to what your system offers.
