I think he's referring to PTS systems (based on his car listed).Not completely true, I got my remote start installed by BestBuy, I went with the Viper start and they program their remote start to be able to be used with the regular key and you don't need any extras. Also, I hope you're not planning on paying the $800 or whatever it is to Honda for your remote start, because that is just NOT the way to go. I called to ask for a price on adding remote start for my car and even the Honda salesman told me himself not to go with OEM and to go with after market instead. I'm very happy with my Viper remote start and I dont need any extra keys except for the on/off remote start button.
Hope that helps!
