This great combination of mechanical dependability and digital ingenuity adds both convenience and security that is unmatched by outdated locks. Through TTLock’s app, users can open or close the lock, create and share access codes with friends and family, and access data logs regarding your lock’s unlocking records and failed entry attempts. Access codes can be revoked at any time through the app, and they can be programmed to work for specific periods of time.

Additional features include a peep-free password option and a low battery alarm which will trigger before your lock’s battery has been depleted.

None of this is required, but it does unlock an endless amount of additional functions for your smart lock and home.

Important Features to Consider

There are a few important considerations to think through before purchasing a smart lock.

  • Bluetooth vs. WiFi. Some smart locks are equipped with Bluetooth, WiFi, or both. Bluetooth connectivity allows you to operate your smart lock via a smartphone within Bluetooth range of the device, which usually means the immediate area around your home. WiFi connectivity means that your smart lock is synced to your home’s WiFi at all times and that allows you to connect to the device through your smartphone from anywhere around the world as long as your phone can transfer data.
  • Door fit. Different smart locks require different methods of installation. Check the installation requirements of a smart lock before you purchase it. Make sure your door’s width is appropriate for the device, and be prepared to drill extra holes in your door for sturdier mounts. Some Smart locks will retrofit with existing deadbolt locks, but not all do.
  • Smart home integration. WiFi connectivity is required for smart home integration with products such as Apple Homekit and Amazon Alexa. Z-Wave certified WiFi connectivity is required for specific home technology devices.

Frequently Asked Questions

What are smart locks and how do they work?

Smart locks are mechanical locks that can be operated and manipulated through Bluetooth or WiFi by smartphones and other smart devices. They work similarly to traditional deadbolt locks, many even still having physical keys as a backup, but can be controlled digitally as well.

Can smart locks be hacked?

There is a risk that smart locks can be hacked, but it’s not any more likely to occur than someone using a lockpick on your traditional lock. Smart locks are encoded with encryption for security against hacking, and Z-Wave certified locks have a standard of security that is stronger than most.

Do all smart locks require a hub?

No. Smart locks only require a hub if you need WiFi capability and the smart lock doesn’t already come standard with WiFi integrated into the device.

Are smart key locks safe?

Yes, mostly. Again, hacking is a possibility, but door lock manufacturer Schlage has said that worrying about such things is equal to worrying about your Amazon account being hacked and that people are much more likely to use brute force to break into your home than sophisticated hacking methods.
