SERVICE KEY 23425557

Has anyone ever had to order one of these? We have a 2010 Camaro in the shop that has had the recall done and we need to program a transmitter. My tech is telling me that in order to program it, we need a service key. Seems familiar as I think that I have ordered one of these in the past. I am trying to order this one now, and twice I have had the order cancelled due to an invalid key code. The key code is in the Zxxxx format and the source is telling SPAC that the key code should be in the Vxxxx format. When looking to see what the key fits (2010-2015 Camaro and 2015-2018 Express/Savana Vans) I find that both vehicles have key codes in the Zxxxx format. I am about to go nuts over this key and the fact that nobody at GM or apparently the source wants to look at the obvious and admit that there may be an issue and the dumb-old parts guy might actually be onto something. Has anyone else out there shared in my pain??? How did you get it handled if so?
