How to use the lock status to create notification

Yes but you need to write a custom app to subscribe to the attribute (depends upon which / whose lock device handler you’re using).
Here is one that I’ve written which works with the stock ST device handler and also with my own custom zwave device handler.
This does more than just jammed notifications.

There may be other free ones available but am not aware of any smart app which only reports on jammed notifications.
My device handler highlights jammed notifications on the device page but you still need a smart app if you want a text or push notification.
