Try this
PASSKEY LOCKOUT RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
the problem is most likely the receiver for the key transponder, the dealer can test this system with a special electronic test tool called tech 2 scanner, u can't replace the parts yourself because they require programming to your cars keys.
I am sure of this solution, sorry you are away from a dealer, but this is what you must do, these security systems do have there problems that is for sure.
