From reading a little here on this site this evening I think the answer to my question is Yes. I will call a dealer to ask tomorrow and get the price. I just bought a new 2013 Three this weekend and have been wondering how people deal with multiple key fobs. I have one to get in the company garage, one for my garage at home and now one for the Prius. Seems crazy and I was asking my neighbor who has a Toyota, and he told me that he can program his garage door with buttons on his mirror. I looked at my mirror and sadly there are no buttons on it. Seems my level three doesn't have it. Did I need level four? But I am wondering if the convenience of installing the garage door opener into the car is such a good idea? My wife clips the garage door opener to the sun visor of her car and it drives me crazy. If somebody breaks in to her car, reads the address on the registration and grabs the garage door opener they can simply drive over to our home and steal much more than what's in her car. !!! She should be using a fob. With Homelink it is probably pretty convenient. But can the thief rip the mirror out of the car and use it? And that also brings up another big question. How easy is it for a thief to hotwire a Prius? If the perp can drive the car he can drive it to my house and open the garage door.
