I guess I'm one of the lucky ones.  Yes, the darn thing was a pain to install.  Did my homework first with the factory manuals for my Lumina.  Then I trained to be a contorchounist(sp?) to get under the left dash. Worked right off. 400 feet?  No way.  But, I did not route the yellow antenea wire in any special place. As long as it will start from my house to the garage. The only thing worth mentioning is I had to replace the remote transmiter recently (after six years).  My Lumina did NOT have remote door locks so that is worth the $$$ and effort!
