I was told that you can install them but you have to buy a new key from the dealer so the chip can be used out of it. They would basically destroy the key so they can use the chip in the remote starter kit. They have to do this because the cars anti-theft system needs the chips info to start and stay running without doing a theft engine kill. The keys from the dealer are about $200- $300 dollars each and they are the only ones that can make them.
The "chip" that is in the key itself is really a resistor. Alot of times they have to measure it and have to install it into the ignition system in order to get the car to start and run. Give it a try.
