TDI Passat Replace Push Button Switch

I have a 2012 TDI Passat SEL. The car has the push button Switch. I believe it is starting to fail. Every once and a while when I push down on the switch it won't start until I repress it. Is it hard to replace? The part is around 100.00. I can't find any photos, videos or any forums about how to replace the button switch.
I greatly appreciate any assistance in this matter.
Thank you.

Have you replaced the battery in the key fob?

I replaced the batteries in both of my key fobs.
The starter button moves or wobbles around a bit while pushing down on it.
Thank you.
