with the motor running and radio off press buttons 1 and 4 on the radio this should unlock the radio
Disconnect the battery again and allow the systems to re-reset. This may solve your problem. Y-THINK-Y
Have you replaced the battery in the fob?

What is the unlock code for a pontiac g6
I may be having the same problem. I replaced the battery. The interior lights, siren, horn, radio all work, but the car will not turn-over when the ignition is turned. I am really interested in how to unlock the vehicle.
The dealer should give you the code number for it.
See if your passenger floorboard is wet. If so, look for corroded wires. If you fix the wires, it should correct your problem. I have a Chevy Venture that had the same problem and this worked.
I know if you just change the battery you hold down the lock and unlock at the same time for about 10 seconds. This will reset the transponder.
You can call the dealership. Just call the parts dept. Read them your vin, then they will give you the code. Hope it helps! D
Take it to the dealer. They get the numbers off the radio and input them to the master GM computer to get the master code. There is no other way.
