Smart Lock - Phone App Question

For those that have a smart lock, is there any way to disable the app on my phone remotely if my phone is lost or stolen? I don’t want someone to be able to get into my home using my phone to open the door. I looked at web portal and I don’t see an option to disable it. So, my options appear to be (1) log out of app every time; (2) if my phone is stolen or lost - remove the battery from the lock; or (3) if my phone is stolen or lost - as soon as I am able pair the lock with another phone - as you can only pair the lock with one phone. Any other ideas? Thanks!
