Well just wanted to let everyone know that I have installed a remote start in my Titanium with push to start that works off the factory key fob.
The installation does not require any additional keys or dealer scan tools. Although I do this for a living, I did install this (soldering all wires) in under 1 hour.
Here is the link to the hardware required to do it all.
It is currently raining so this is what I have to show for now, I will try to make a better video showing all the install tomorrow if I have a chance.
