You need to remove that... It's a ghost.
When you factory reset the lock, you really don't need to exclude. Remove that ghost you created or you will wreak havoc on your mesh.
Now with the schlage locks you need to pair them within 2 or 3 feet of eachother because of the whisper key exchange they do during pairing. After that you can move things to their final resting place. You would also want a beaming repeater as close to the lock as you can.
Now that said, you should be pairing your mains based devices first (electrically powered) and battery based devices second. Read this post and pay attention to the z-wave section. Especially the section on building a strong z-wave mesh. The overall post though will help you avoid some gotchas! Get rid of that ghost!
