Schlage Encode Issue

[Toni7692]

I had my lock installed about a montha go.  Everything seemd to be working fine with my app.  Airbnb assigned a code to a guest and a couple of days before the guest was due, I got a message that read I needed to check my Schlage lock as it was offline.  It was on its 2.4G band and codes were all working.  Now, after two days of trying to get it going again, it seems to be locked.  I did a reset and it isn't recognizing my programming code.  Any suggestions?
