I just purchased a 2005 cobalt coupe. The dealer was only able to provide me with one keyless entry remote without having to order and program a new one. I found a site that I can get a new one pretty cheap but I don't know where to begin with programming it to my car. I ran across these instructions for a Tahoe and was wondering if they would work on the cobalt as well.

Programming Instructions:
1. Close all the vehicle doors.
2. Insert the ignition key into the ignition lock cylinder.
3. Press and hold the door unlock switch.
4. While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
5. Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
7. Repeat the previous step to program up to 4 transmitters.
8. Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
9. Operate the transmitter functions in order to verify correct system operation.

If this won't work, could someone provide the correct instructions?

Thank you for any help at all!
