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

We've replaced the 3 "D" cells in the base unit and the 12V cells in the two
buttons but still no joy.

12V cells?


Any ideas?

I think that's common, and not cheap.

I'm thinking the sets operate around 400 MHz but doubt if anywhere near
wifi.
I don't know if there is a frequency adjust, but I would suspect the
frequency is off.
They are cheap enough to replace the whole thing.
