As an Airbnb host, a good smart lock is an extremely important purchase. I've gone through my fair share of smart locks, but none have been more reliable, affordable, and easy to install than the SwitchBot WiFi Smart Lock Pro, which I raved about in a recent review. Right now, you can get the bundle that has everything you need (it comes with the smart lock, keypad, and hub to control it remotely) for just $84 (originally $199.99) during Amazon's Big Spring Sale—that's the cheapest it has ever been, according to price tracking tools.
The main reason I love this smart lock is its reliability. A smart lock's most important job is to open and close reliably, whether that's physically with a key, with your finger, code, or remotely through the app. That seems like a pretty basic requirement, but you'd be surprised how few smart locks nail it—the SwitchBot has been the only smart lock to not fail me in the year I've been using it so far.
The installation was also the easiest of any smart lock I've installed. You only need to remove the lock faceplate from inside and use an L-shaped hex wrench that comes in the box to mount the smart lock. It took me seven minutes to finish. There's also an option to glue the hardware for a complete tool-free option.
The smart lock also retrofits most locks, and since the installation is so easy, that makes it perfect for renters, too. Some nice features are the auto-lock (I love not having to close the door behind me), a status detector that notifies or alerts you of activity, and being able to send permanent or temporary codes to family or guests. It also works with Amazon Alexa, Google Assistant, and IFTTT. The battery lasts up to nine months, according to SwitchBot, but it'll depend on use (it was accurate for mine).
