Yes, I assume you had your Schlage lock connected to your Wink system. Once a Z-wave device is connected to a system, it needs to be removed before it can connect to another system. This can be done by the factory reset you did. It can also be done by a remove process of the Wink system. SmartThings also has an exclude mode where you can remove the connection to another system. I am sure Rboy has a more robust handler with many more options, but if all you need to do is lock and unlock the Schlage, the SmartThings handler works fine.
