Can Smart Locks Be Trusted? What You Should Know About Smart Lock Safety

Smart locks are a safe pick for most households, and features like remote access and programmable schedules can make them safer than conventional locks. There are still concerns about security, but they usually have more to do with the way families use smart locks than with the devices themselves. 

Take a closer look at smart lock safety and learn why these tools are a great fit for your St. Louis home.

What Are The Security Concerns Of Smart Locks?

There are risks associated with smart locks, but they largely depend on your own safety habits. These are the central concerns to watch for:

  • Predictable codes: Easy-to-guess passcodes are the foremost security risk when it comes to smart locks. As you might imagine, creating a code of ‘1234’ is asking for trouble. It’s also wise to skip birthdays or anniversaries and other overly simple combinations. 

  • Cyberattacks: If someone hacks into your wireless home security system, they may be able to engage the smart lock. Keep your passwords updated, turn on two-factor authentication, and always run manufacturer-recommended firmware and software updates. 

  • Code smudging: Touching the same buttons again and again can leave marks that point to your code. Switch up your passcode and wipe off the buttons often.  

Internet outages and blackouts may also interfere with your smart lock. Most will keep working at the door since they run on their own batteries, but you will probably lose access from your phone. Numerous models are equipped with backup keyed systems, which gives you another way to get it in. 

Pro tip: Smart locks with backup keyed locks are typically built to resist bumping, a common break-in technique used on conventional locks.

Why Smart Locks Are Safer For Your St. Louis Home Than Standard Keyed Locks

It’s easy to see the danger of keeping a house key under your welcome mat, inside your mailbox, or within a rock decoy. Whoever comes across it will have instant access to your house and your possessions inside. Even when handing a key to trusted relatives or friends, it can find its way to the wrong people and be easily duplicated at the local hardware store. 

Fortunately, the days of depending on house keys are behind us. Smart door locks allow you to go keyless and offer many advanced features to strengthen your security. 

What Gives Smart Locks The Edge Over Standard Locks?

Smart locks are a core part of modern security systems. They come with features that make them a stronger choice than traditional locks. Some standouts include:

  • Automatic locking: You can program your door to lock itself after a set time period. You no longer have to worry about forgetting to lock up.
  • Scheduling: You can set smart locks to lock at whatever time you want and include them in whole-home routines. To illustrate, you might have your system arm, lights dim, and door lock all together when you go to bed
  • Remote management: You can quickly check your smart lock's status by accessing your home security app. It’s also possible to unlock or lock your door remotely.
  • Instant updates: You’ll get alerts to your smartphone app any time somebody opens or closes the lock, letting you know who’s coming and going.

On top of that, anybody who needs entry to your home can be assigned their own code, so you’re not using the same one. You can give or revoke access whenever you need to.
