It depends on your lock model and it’s behavior. For example with a Schlage BE469, if it’s in jammed states, you can send it a lock command it will try to lock itself again. However if the door is physically in a state where the deadbolt is being blocked, then it won’t help. If it’s in a state which is partially blocked, it may help. It’s contextual.
Most locks do send this including Schlage and Yale deadbolts, it need to be captured and processed by a compatible DTH and processed by a SmartApp which will notify you.
Not necessarily, if you have the DTH report to ST that the lock was jammed. You can setup a WebCoRE rule that captures that jammed event, notifies you and automatically sends a “lock” command to the lock. If it fails a second time you’ll have to someone over to see what’s going on.
