We have used both the Schlage Encode and the Yale Assure locks and they are both excellent. Do you have the Schalge Encode Model? If so, I would just keep it as the new Airbnb interface should be available soon. Also, some Hosts have been complaining the Yale interface with Airbnb has stopped working recently. See thread below. Forgot to mention you can use a 3rd party smart lock service to generate codes automatically. I have heard RemoteLock mentioned, but its a paid subscription service. I would just wait for the Airbnb smart lock integratio to go live.
The only negative I have heard with the Schlage is that it can have problems in coastal areas with high humidity and moisture getting in the lock and causing issues. We have not experienced that however (property with Schlage is in a dry climate). It doesn't look like your property is in a coastal area though?

The new Airbnb interface should be available soon. I would go ahead and install the Schalge (if it's the Encode model) and just manually create and send the codes to guests until the new interface is available with Airbnb.
Schlage Master Codes
Set your master code to 4 digits (not 6) when installing the lock. This is because all codes that are used after you set your master code must be the same number of digits as the master code. The new Airbnb integration says they will be using 4-digit codes when it goes live and you may have issues if you use a 6 digit code for your master code. You can change your master code, but it involves doing a factory reset on the lock (a pain). Be sure not to loose the codes that come with the lock manual and paperwork in the box.
Schlage Encode Backup Key
Schlage only provides one backup key with the lock. It's best to make several copies of that key just in case before installing the lock. The backup key is only needed if the batteries run down and the keypad won't work. You do have a battery indicator in the App and on the lock. Most Hosts keep a key as a backup either in a lock box or hidden somewhere just in case a guest needs it to get in if the keypad doesn't work. Most Hosts report about 6months of battery life. That is typical for a Wi-Fi smart lock. It is a pain to have to change batteries every 6 months, but all the benefits of the smart lock are worth it.
