My neighbor asked me to look at her wireless doorbell, which suddenly
stopped working properly. The buttons still work if you move them close to
the unit but they no longer work mounted on the outside of the door frame.
We've replaced the 3 "D" cells in the base unit and the 12V cells in the
two
buttons but still no joy.

Any ideas?

are you certain the new batteries are really good?

Checked them all out with a voltmeter, first thing.

Did you just check the open-circuit voltage, or did you test them
under load. I usually put a100 ohm resistor across the battery
terminals when I test them, that puts a 10 - 30 ma load on the 1 - 3 V
battery which usually is enough to show either good or weak.
