2006 cts remote starter dilema

Thanks for advance for reviewing this topic. Ive done alot of research up to this point.

I have a cadi 06 cts with the pk3+ immobilzer system and ob2-can. It has heated seats, Nav,RDS, xm, 2 driver positions,etc What I want to do is install a 2way remote starter with alarm/door lock features.I have installed several remote start sytems in the past with fairly ease, but looking for more input before i get started. Looked over several sites and it seems the xk01/xk06 is the way I want to go over the gmbpdl /gm-sl2.

Questions I have, is this the easiest bypass to use for this car? I want the fewest connections possible to retain the factory wiring. Is there a site that can tell me all of the available starters that have the D2D data port compatibile with the xk01? I know it only saves me a few connections, but might as well go that route if I can.

I need the longest range starter unit, as the car needs to be started from a 10 story building. I currently have a bulldog deluxe 500 2way in my other car that easily covers that distance and havent had any problems with that unit ever. I just need a newer unit with more secure features in it and anti-grind. looked at possibly the cs2900II fm from crime stopper w,D2D output.

also plan on installing a bluetooth kit at some point, if that might play into things.

Any opionions would be greatly appreciated

Both keys have pk3+ printed on the shaft.   I have seen sites that state I need both modules to get the system to work correctly.

Is there a site to enter my vin to positively verify this for sure???

Thanks

Also, the xk01 says I need to cut/splice a passkey wire for pk3 systems. I have no intentions on doing that. Id rather leave a blank key in the car first and use the gmbpdl unit.  With the xk06 -pk3+ systems if I remember correctly.

any way to verify this? This is where I need the most help as I dont know for sure either way as there is so much contradicting info on this car year. I want to make sure I cover all the bases so i have a clean and efficent install process.

Thanks again

Thanks for the factory anti grind info. I wasnt aware of that.

The problem I face here is that the listings for this vehicle state coverage for pk3 systems with the xk01 and gmbpdl. My key says pk3+ which I dont believe is covered by the bypasses listed above. Which means I might need another bypass for the pk3+ immobilzer. Or is the fact these bypasses also cover passlock 1,2 and passkey3 mean it will cover the pk3+ system also? From what I understand the pk3+ is passkey 3 and pass lock combined together.

The reason Im unsure is that the xk06 bypass specifically states pk3+ coverage, while the other bypasses do not, but all sites indicate the xk01 and gmbpdl/gmsl2 should work with my vehicle. I just want to be 100% sure before I purchase the bypass kit.
