You'd have to have a decent amount of work done to have the factory kit installed. It's more than just the remotes. Your best bet is to go aftermarket and get a kit that includes remote start. I am having a Viper 5301 (one-way) kit installed on the 13th. All total it's running me about $330.
There are cheaper kits though, such as the Viper 5101 (one-way but still effective) that only run about $210, installed + the bypass module which you can pick up for $39 online and have installed for another $30 or so.
$280 will have you setup nicely.
Where did you get yours from?
Best Buy and Amazon.com. The links in the post are the same links I used or would have used. Best Buy is handling the install as it's included in the price.
