I don't think that I have a whole lot to add to this discussion except for what I am coming to learn as of late.
my dad and I get our kicks from fixing up wrecked jeeps. We are on our 4th jeep right now. Its a 2002 sahara. The problem was that in the accident, the battery tray pretty much busted the PCM in half. So I got us a PCM off of ebay. Now, as the people in this particular thread are probably aware, its not so simple. this vehicle is equiped with the sentry key immobilizer system. My understanding of how this works is there is a key in the PCM, and in the Ignition switch. Then there is a transponder in the key itself. This is why a replacement key costs me 50 bucks from the dealership. Basically what happens now is if you try and start it, it runs for 3 seconds and shuts down. I'm thinking that not all wranglers have the SKIM setup. But my impression would be that a remote start wouldn't work if you had a SKIM equipped jeep, unless you have a spare key close enough to the ignition switch. I think this is what KK was talking about, can't remember.
anyway, I think that from a technical standpoint its more than possible. an experienced car electronics guy can bypass the clutch stuff and install his own safeguards. But its my opinion that its still dangerous. and I don't think that it would really do much for resale. but what do I know.
bottom line: I live in Wisconsin. My frozen tundra heart bleeds for all you chilly socal folk.
