One other possibility is the actual RKE receiving antenna. i seem to remember someone on here trying to put in a sub under the rear floor and discovered that this is where the antenna is.
Make sure the antenna wire is clipped into the harness.
I haven't tested distance on my new D yet, but it is so true that the environment matters. On my last D, I had an aftermarket that was supposed to be good to 2000ft. It was typically good line of sight, if I could see it, it would start. Through buildings was still good for 200+ feet. But - if a cell tower was within a block, forget it. At my usual supermarket where a cell tower is right across the street, I've held the remote a foot from the car and it would refuse to lock/unlock/start - even inches from the remote start antenna.
To the poster that had it work 200 feet from their car in a ramp, I suspect the ramp is pretty well shielding outside signals, and the concrete tunnels the signal, bouncing off the low ceiling.
I don't get why car manufacturers don't get it - they could easily offer an upgraded two way long range unit - I'd sure buy it if it were well integrated. Now I'm reluctant to add an aftermarket system since I don't know how it will play with my keyless-go remotes. Don't want to mess those up.
