I am trying to find out if I need to purchase a transponder bypass with a remote starter that I am putting in my mother-in-laws 2002 RAV for her birthday. I couldn't find anything on the net about it for that model year. She has the 4WD model. The key looks like it may have a chip in it but since I couldn't find anything online about it, I am skepitcal. Also, we live in the US if that matters! Thanks!
