I just bought my first Lexus, an 04 black on black is300 5spd with 37000 miles! Love the car so far, but It didnt come with a master key. I called Lexus and told him what I wanted and he says brace yourself! in order to reprogram a new remote you need the old one! he sys i have to replace my "computer"! lexus will do that one time only for free, I just have to buy two new keys at $320 a peice! Then pay to have the new "computer" installed, the new keys cut and programed comeing to about $1000! For keyless entry? So this is my question to you, does anyone know any other way to program a key without the old one, and if not, does anyone have an aftermarket alarm/keeyless entry system that they would recomend? Being So new to the forums and the car any feedback would be greatly appreciated. Thanks!
