I did consult an Owner's Manual and found 2 specific passages in relations to matching the key fOB and key. I lofe is goint well. rom 2-11 Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have only four transmitters matched to it. Since all vehicles come with only two transmitters, you must check with your dealer for information on how to obtain additional transmitters. All transmitters must be present when replacement or additional transmitters are being programmed. From Page 2-21 To program the new key: _ Insert the current driver’s key (black in color) in the ignition and start the engine. If the engine will not start see your dealer for service. _ After the engine has started, turn the key to OFF, and remove the key. _ Insert the key to be programmed and turn it to ON within ten seconds of removing the previous key. _ The SECURITY light will turn off once the key has been programmed. It may not be apparent that the SECURITY light went on due to how quickly the key is programmed. _ Repeat the Steps 1 through 4 if additional keys are to be programmed. Matt, GM Customer Assistnace
