Hello everyone! I own a 2004 Impala and am having a lot of difficulty programming my key fob. The first key fob I had started dying and would work sometimes and then stop so I figured it was the battery. Changed the battery and then it stopped working all together. Bought a new one that came in today and it has a fresh battery (checked with multimeter) and I still can't program it. I used Kermone's guide and never heard a beep until I completely exited out of the setup menu. I held down the lock and unlock buttons for about a minute before the "push fob" message timed out. I even tried to hold down the DISP button to see if it would flash like stated in the guide but it just kicked me out of the setup menu. Any help on this issue would be greatly appreciated.
