Are keypad door locks safe?

You are drawn to the idea of eliminating house keys and moving to a modern smart locking system, but safety is still a concern. Are keypad door locks truly safer than the old-school locks they replace? The easy reply is yes. But before adding one to your San Diego smart home, there are several things you should consider.

Why upgrading to a smart lock makes sense for your San Diego home

The inherent problem with traditional locks is the need for a key. Keys are frequently lost and simple to copy, which can be a real problem if they end up with the wrong person. Besides, older door locks are more vulnerable to bumping, picking, and forcing. Modern smart locks do away with keys completely. The models that provide a backup keyed lock frequently use a different type of cylinder, making them resistant to common break-in methods.

Are there any risks with keypad door locks?

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

  • Unauthorized code usage: Codes must be kept secure. It’s also a good idea to change them periodically and never use predictable codes like “1234.” If you have to give a person one-time access, you can create a code and then remove it once it’s served its purpose.

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

  • Technical problems: A battery failure, WiFi disconnection, or software bug can create problems. However, essential local features like keypad entry still work if your WiFi is offline, but you may lose app functionality. Models with backup keyed systems can offer another way in.

Do smart locks still function during a power outage?

Yes, your smart lock should still function when power is lost as it gets power from batteries, not your wired electricity. You’ll still be able to use the keypad, Bluetooth, or fingerprint scanner, based on what your system uses.
