2014 Cayenne - Entry & Drive Button

[elav01]

Hello, I have a 2014 Cayenne Diesel and the "Entry & Drive" buttons on the passenger side stopped working.  The "Entry & Drive" buttons are the rubber buttons on the exterior door handles that you press to lock the vehicle.  The driver's side buttons work fine.  The front passenger side button feels like the switch is no long lined up - you can press the rubber and you don't feel it clicking.  The passenger rear door button feels like the switch is still in place but perhaps isn't working due to the front door not working?  Does anyone know if I can investigate this more using Durametric, or is this more about opening up the door to check it out?  Can you replace just this switch or am I looking at replacing the entire door handle assembly?  Thanks in advance!

Ok, so I removed the door handle and while I don't think they intended for people to take the door handle apart I did.  It turns out that they embed the wires and the door switch/button in silicone.  I was going to dig it out and get a closer look at the button but then I realized that the rubber boot that goes over the button has a rip.  I'm pretty sure moisture got in there and ruined the switch, so I'll purchase another door handle.  Here are some pic s.. .

It looks like you can only purchase handles in primer - and getting it painted make this pretty expensive to fix.  Has anyone purchased the Chinese versions on eBay? I may order one, remove the silicone from my broken handle and try and swap over the switch so I can use my existing painted handles.  Anyone try this before?
