do it yourself...pretty simple. I'd suggest finding a dental tool that's like a hook so you can pull out the clip that much easier. and it is easier if the car hasn't been started at all...you're hands will thank you for it.
It took me almost two hours to do it, but having some experience...easily can be done under an hour.
Anybody know a good (great) trustworthy, independent shop in Ventura or Santa Barbara County, Calif. that can install a SSK/DSSR? I'm still trying to decide independent vs. dealer install.
