My neighbor asked me to look at her wireless doorbell, which suddenly

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?

I had one of these units. Made in China POS construction. Will work for maximum of two years and then the electronics are kaput in my estimation. Chuck it and replace or put in a wired unit.
