A while back, I did a DIY for removing the 'pill' and placing it by the ignition switch:

I plan on doing a remote start on one of my cars, but haven't gotten to it yet. The best location that I found for the 'pill', is where the pencil tip is in the picture below. Simply attach it to inside of the rubber trim that goes around the ignition switch.
That has worked fine for starting and running three of my Boxsters on Audi/VW Keys. I can not verify that it will operate the trunk and frunk, since my spare keys do not have the internal electronics, but is fully functional with the original key fob.
