I am interested in modifying my key fob so that I can operate my 2017 Boxster S convertible top and windows from outside the car. There is a product that does this called "Smart Top" produced by a company called Mods4Cars. Is this the only product that will do what I want? Does anybody have experience with the installation/operation of the "Smart Top"? The installation looks pretty scary to me by cutting wires in the car's computer module(s). However, my aging (70) arthritic bones have difficulty getting in/out with the top raised.
