What happens when you turn the key? Do you hear a starter solenoid click? Do you get a message on the console? Is there a code (do you know how to get the codes?)?

Sounds like a problem with the starter. If the PASS key system was at fault, the PASS system fault light would be on.

Check for battery voltage at the large cable connection to the solenoid. Then check for battery voltage at the small solenoid terminal while a helper holds the ignition switch in the start position. If you have battery voltage, then you'll need to repair the starter. I always recommend having the existing starter repaired by a local AC Delco starter repair center vs. installing a chain store starter.

If there is not any battery voltage at the small terminal when the ignition switch is held in the start position, then check the connections to the gear selector switch which is mounted on top of the transmission where the shift cables connect.

As a last resort you could bang on the starter lightly with a hammer

Well and as a real last resort you could actually replace it

If you find out for sure it is getting the juice just fine
