There's two primary issues with them.
1) navigation button plastic buttons falling inside the TX.
2) the actual tactile switch electronic components failing.
This video is about replacing the tactile switches.


The original parts for them seem to OMRON BF3-1060.
The switches measure 6x6mm with a switch height of 7mm, not including the through-hole legs.
