This is replacement rubber pad only – no internal part or electrical components.
Plus two brand new sealed lithium Panasonic brand batteries.
The buttons on the remote / ignition key get worn out quickly, but can easily be replaced by just prying off and replacing the triangular button insert on top of the key.
This is available as a separate part, rubber pad.
Changing the button cover is easy, using the smallest flat-head screwdriver carefully pry the pad off, the replacement one just press-fits right into place. It is literally 45 seconds to do the swap.
