Hello Nihol. While I don't price installations for our company, I can tell you that we typically do Remote Start Alarms with Keyless Entry on Toyota's like yours for around $450. This would be a system from Directed Electronics. Different requested features of course affect the final price. If you haven't already had the work done, I request that you call our store and request Jeff on the phone since I am aquainted with your question.
I had them put a stereo in my truck and it hasn't been anything but a problem since will not go back hasn't worked right and broke my dash cover
I don't work for them but seems like it would depend on what additional parts would be needed for adapting the kit to your vehicle. At least when I was getting a new stereo system installed that was part of the equation. They had a basic kit or you can bring your own and they do labor and make sure it is installed correctly. Hope that helps. They did really great work on the stereo system I have installed. Still working great and is over a year ago now.
Depends on what brand of alarm and remote start you want.
