i bought a 23 Sierra 1500 diesel and it only came with 1 key. I had another key made but the keys are #3 & 4 in the system so I can't use the memory functions.

I contacted the local dealer and they said they won't configure keys they didn't sell. if they won't fix the problem, is there any way to get these keys coded? I'm not spending $800 on 2 new keys for their stupid policy.
