1. I have a fob just this one but I want to purchase another but how do I tell if I have a 302w or a 502w?
2. Does this work with RS7-G4 ?
3. So, I'm looking to replace this remote for an otherwise totally working Crimestopper Cool Start RS7-G5 starter that's installed and fully working. The remote we have will no longer take a charge which is why I'm looking to just replace the remote. That being said, does the remote come with instructions for how to hook it up to the already installed starter in my car?
