However, you need to swap out an internal module if you want to switch from Bluetooth to, say Wi-Fi or Zigbee. That means you can control it from your smartphone, whether you have one of the best iPhones or best Android phones, or a smart speaker like the Amazon Echo, Google Nest Mini or Google Nest Hub Max. It works with Alexa, Google Home, HomeKit and SmartThings, and will also support Matter in 2023. The support for multiple smart home standards make the Yale Assure Lock 2 one of the best smart locks available. The only thing missing is support for Apple HomeKit. That module can handle multiple locks, so it’s a great low-cost pick for adding remote control to several doors at once. Note that you will also need the August Connect module (about $60, sold separately) if you want to control and monitor the lock remotely. And, when you move out, you can quickly and easily remove the lock and replace it with the old one, keeping your deposit safe. There’s no need to replace the cylinder it will continue to work with your existing keys, keeping your landlord happy. If you rent your home, the August Smart Lock is the best smart lock, as it’s very simple to install on top of an extant deadlock without replacing the cylinder or key.

You can pick up this smart, full-featured lock for less than $100. If you want to add some smarts to your home without spending too much, the August Smart Lock has most of the features you'll need, at a reasonable price.
