I don't work for Lockitron, but I am a moderator on the forum. The system thought you were a spammer, so it incorrectly held your first few posts. Sorry about that.
Regarding the issue you're having - with the key in, is the action of locking/unlocking manually (turning the thumb turn) smooth, or rough?
You're using the included deadbolt from the box?
If so, it might be possible that the tailpiece wasn't rotated all the way before attaching the Bolt unit. Check Step 8 (p. 13) in the manual.
