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 really safer than their time-honored counterparts? The simple answer is yes. But before integrating one into your Brownsville smart home, there are some things you should know.

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

The main issue with traditional locks is the need for a key. Keys are often lost and simple to copy, which can be a real problem if they fall into the wrong hands. On top of that, older locks are more vulnerable to bumping, picking, and forcing. Modern smart locks remove the need for a key completely. The options that have a backup keyed system frequently use a different kind of cylinder, so they can’t be circumvented by traditional methods.

Are there any risks with keypad door locks?

Even though they’re typically safer than standard locking systems, keypad door locks do come with some risks, including the following:

  • Unauthorized code usage: Codes have to be kept secure. It’s also smart to update them periodically and avoid predictable codes like “1234.” If you want to give a person one-time access, you can create a code and then eliminate 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 updating apps, firmware, and passwords often. Integrate two-factor identification whenever you can.

  • Technical issues: A battery failure, WiFi disconnection, or software bug can cause issues. Generally speaking, core local features like keypad entry still work even if your WiFi is down, but you may lose app functionality. Models with backup keyed systems can give you another way in.

Do smart locks still work during power failures?

Yes, your smart lock should still function during a blackout as it runs on battery power, not your home’s electricity. You’ll still be able to use the keypad, Bluetooth, or fingerprint scanner, according to what your system uses.

Why Vivint smart locks are a great fit for your home

Vivint’s smart locks work reliably with other equipment within your smart home environment. You can set a rule to turn the lights on whenever the door is opened, or configure a whole-home scene with multiple automations. For instance, you can dim lighting, lock your door, arm your system, and even change your thermostat simultaneously when you head to bed. And you know what else? Your locks and all your smart home components are completely accessible from the convenience of the Vivint app.

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