The Crossfire guy at SOS doesn’t talk on the phone, he only does emails.

They are going to drop a new transponder in and program it once they realize it doesn’t have one. Since they think you don’t have a working transponder they will write the new transponder over one of the key tracks at random. You have a 1 in 8 chance they write over your current transponder. Every Crossfire was made with two keys from the factory. Key Track 1 and 2. You have a total of 8 key tracks available.

The dealer almost always held 1, if you have 2 you’re lucky.

If your current transponder, in your pocket, is 2 and they write to key track 2 either it won’t work or the one in your pocket won’t work (I don’t know what determines this but they won’t both work). If they write to key track 1 then you’ll have two transponders that work. They might write to 3, or 4... in which case it doesn’t matter.

I would email them, explain the situation and ask if you could get a valet key cut without the transponder. When it arrives with your new fob, put the transponder from your key right now, in your pocket, into the valet key. Voila, you have a working fob and a fob less key that will run your vehicle (good for letting it idle to warm/cool while you lock it with the fob and stay inside your toasty/cool house/work in the morning or whatever).
