I searched the forums for this but found only discussions of Toyota remote starters. I can't afford them. About a week after I got my new 2009LE I had an ExCalibur model RS-310-EDP installed. It seems to be working OK so far, but it's warm weather now. Cost me $250 and has remote door locks too. (If you start car remotely, your Toyota keyless entry won't work, have to use the ExCalibur gizmo to unlock doors, or use your key, and that's only on drivers side). The installer did not put a hood interlock on this one (I had one on my 2000 Corolla too). But this Valet Mode is easier to get in and out of, at least. The remote on my 2000 Corolla would only work to about 0 degrees F. Lower than that it WOULD start but the engine was turning too slowly for the gizmo to detect that the engine had started. It would try 3 times and quit. Hope this one works better. My early morning drives are about 2 miles, not enough time for engine to warm - THAT'S why I think remote starter is important for me. I usually only use in once a day. So... anyone else have any opinions on this?
