The locksmith would have to be subscribed to GM service programming, and have a Tech 2 scanner. The dealer is usually the only place to have this done. $400 is really high for this service. You might consider a different dealer. Any GM dealer should be able to do this for you. The keys usually run around $40 to $65 each. Only genuine GM keys are recommended. The cost of programming is usually around 1 hour of labor.
