First of all the factory remote useage sucks...only reaches like 35 ft. Go with something like this...only costed me 119.00 and so easy to install. NO Wirecutting involved. here's a link to the website where I got mine. Didnt need any transponder either and mine has been going strong for over 2 years. Ive even done installs on others cars for some extra $$ and purchased through this site. MIne is the code alarm 1 button CA420. http://www.autoalarmpro.com/inc/sdetail/108
