Following up on Don's suggestions, put the KX1 in the 'fridge, and
check it for key down output once a minute. If there's a sudden drop
in power, it's likely a solder connection. If it's a gradual drop,
it's probably not a solder connection. I'd keep the batteries outside
the fridge to eliminate them as the cause of your no output problem.
If you don't see the problem, put the batteries in the fridge and
repeat the test.
Let us know what you find.
