How do you program a 2004 Pontiac vibe key fob?

To program a 2004 Pontiac Vibe key fob, first, sit in the vehicle with all doors closed. Insert the key into the ignition and turn it to the "On" position (not starting the engine) and then back to "Off" five times within 10 seconds. The doors will lock and unlock, indicating the programming mode is active. Press and hold the "Lock" and "Unlock" buttons on the key fob simultaneously for about 15 seconds, then release them; the doors should lock and unlock again to confirm successful programming.
