...2000 Toyota Celica? I have a 2000 Toyota Celica (automatic) that already has a remote starter installed in it however, it no longer works. I took it in to a place to have it checked out and I was told that the "brain" of the unit was dead. The starter that is currently installed (and not working) is a Command Start and the unit I would like to replace it with is a Pro Start. The wiring is already done and both remote starter controls have the same four buttons (start, lock, unlock and trunk). When I hit the start button on the Command Start remote the lights flash but the car doesn't start. My question is, can I swap the Command Start unit for the Pro Start unit using the existing wiring setup? Is it difficult to do? If it is a little too tricky for someone without any car electrical knowledge (meaning me) to do, what would be a realistic cost "estimate" to have it professionally installed? My mom actually has the exact same car (a 2000 Toyota Celica) and when her remote starter was installed the labor cost amounted to $180. I've taken my car back to the same place that worked on my mom's car and they told me it would be the same price ($180) to swap the starters. It doesn't seem logical that I would be charged that much especially since all of the wiring is already in place. If anyone has had experience with this kind of an issue I would really appreciate any information that you can give me! Thank you!
