2004 Trailblazer Remote Keyless Entry

I just bought a 2004 Chevy Trailblazer that did not come with keyless entry installed. I have a few questions before attempting the project.

Is there a factory kit that can be purchased from GM that simply plugs in somewhere and activates it? (like I am doing with the cruise control switch swap). If so, does anyone have the GM part #?

If not, other than the keyless entry kit, what else would I need? (looking at getting the deluxe one from 12voltshop)

Will I need to purchase this Databus Interface Kit also? (wasn't sure if that was just for remote starter kits or not)

Also, roughly how hard is this to install?  If all I have to do is plug wires into harnesses or strip wires to tie into, I don't mind doing that. If it requires soldering or pulling all the door panels off, I would have a pro do it then. I wasn't sure if the databus kit made this as easy as installing a stereo or not.

I haven't found anything on the 2004 keyless entry topic in the forums, mostly about remote starters, but wasn't sure if they all tie in the same or not. I appreciate any info that can be given.

Thank You

Aftermarket Keyless entry isn't too bad in the trailblazer as long as you do buy the gm databus interface. with this module you will only hook one wire up to do both the lock and the unlock, inside the vehicle. If you don't buy the module, then that is when you have to do all of that other stuff.

OK, I am looking to get the Deluxe Remote Keyless Entry from 12voltshop.com. What data module do I get? Is it the GM Doorlock & Alarm Databus Interface Kit ( http://www.12voltshop.com/cadetails.asp?prodid=GMDL1&cat=22&path=1,22) or the Passlock 2 In 1 Wire Bypass ( http://www.12voltshop.com/cadetails.asp?prodid=PLDATA&cat=13&path=1,13).

Not sure if I need the databus interface kit or the factory bypass kit.

Thanks again for the info.

OK, the wife decided she does want the remote start feature too. So, according to NowYaKnow, I need the PLDATA. Do I also need the GMDL1?

I realize that the KE and RS kits connect to the wires coming from the PLDATA & GMDL1 modules, but how do the modules connect into the vehicle system? Do they have harnesses that simply plug inline? I haven't been able to locate any pics that show one installed, or instructions that show where they plug into. If someone knows of a good website that shows this, please let me know. I would like to order the stuff within the next few days, but want to make sure I have everything I need.

I appreciate any and all info given. Thank You!!
