Have a response from someone in the Jayco Forums.
As far as I know this model doesn't have batteries. Mine looks exactly the same and it runs off 12-volts from the coach batteries, supposedly hot all the time. Look in the hinge area of your door and see if you see two spring-loaded plungers and mating contact areas. That is how power is passed to the lock assembly, it happens only when the door is closed or very close to it. My reply;
You nailed it.
Cleaned up both areas to get better contact and works now...but will keep an eye on it and keys in my pocket.
