The remote start probably has a hidden key by the ignition switch which now will have to be re-programmed also, I think you can do that easily having 1 key already programmed, you just put the good key in ignition, turn on-off and quickly put the hidden key in and turn it on, hidden key might be nothing but the blade though, best buy should do this part for free, the AC must be a separate problem because the key has nothing to do with it except to start the engine to run the AC, the dealer is responsible for that

I have a valet key for my LT, starts the car just no remote buttons, the keys have a RF ID pellet in them, the aftermarket remote start's I've seen they hide the key buy the ignition switch and the remote start module makes it happen, on the cruze I'm not sure what the remote start system does--must use the GM buss

Valet Key? Was this the Camaro ignition recall key?

I dunno-got it on eBay, had it cut and it programmed just fine, looks like a regular key and I use it for my hidden key
