ok so my car has all the options except power windows and doors, and im tired of having to fumble through my key ring of 20 damn keys just to find the door key, so i want to just be lazy and push a button. i went on ebay to see what they have, and some people are offering kits to install. so i want to know if these things work or are they just BS? has anyone tried, can anyone recomend a particular brand thats good? thanks!
