Are keypad door locks safe?

You are drawn to the idea of getting rid of house keys and switching to a modern smart locking system, but you have concerns about safety. Are keypad door locks truly safer than their old-school counterparts? The easy reply is yes. But before integrating one into your Dover smart home, there are several things you should consider.

Why smart locks are a better choice for your Dover home

The inherent problem with traditional locks is the requirement of a key. Keys are frequently misplaced and easy to copy, which can be a real problem if they end up with the wrong person. On top of that, 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 system usually use a different kind of cylinder, making them resistant to established break-in methods.

What are the risks of keypad door locks?

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

  • Unauthorized code entry: Codes must be kept secure. It’s also wise to update them often and steer clear of predictable codes like “1234.” If you want to give someone one-time-only access, you can create a code and then delete it once it’s no longer needed.

  • Hacking: Network breaches are always a hazard for electronic devices connected to your smart home. Offset the risk by updating passwords, apps, and firmware regularly. Integrate two-factor identification whenever you can.

  • Technical problems: A battery failure, WiFi disconnection, or software bug can cause problems. Generally speaking, core local features like the keypad still work if your WiFi is down, but you might lose smartphone app functionality. Smart options with backup keyed systems can give you another way in.

Do smart locks still operate during power failures?

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

Why select Vivint smart locks for your Dover home?

Vivint’s smart locks work smoothly with other devices within your smart home environment.

Your locks and all your smart home components are fully accessible from the convenience of the Vivint app.

You’ll always know who’s coming and going as Vivint systems keep track of smart lock codes. You can also set as many as 50 unique access codes.
