You have to be giving the ignition system 9V or higher to be able to move the shifter, it has an electronic lock. I couldn't find anything on bypassing the lock at the moment.

If you need to move the vehicle (say out of your garage).....
you can do what tow truck drivers do.

In the engine compartment- you can undo the mechanism at the transmission- this would allow the shifting of the trans to neutral- and allow the vehicle to be rolled.
The shofter would still be locked... but at least the vehicle can be moved.

note the transmission dipstick cap- right above that- I believe is the connector they undo..

My parents had something similar happen to their Impala. It turned out the wiring for the shift lock in the console was so short that the movement/bend of the wire was right where the small section of stripped wire was fastened to the connector. One of the wires broke but would make intermittent contact. It prevented removal of the key as well as shifting into park.

Thank you all for the replies. had to get the car towed and yes rbarrios, that's exactly what the tow truck guy did, unhooked it. As of now the car is in the shop and the first response is the "computer got fried somehow" unfortunately I'm not near a Chevrolet or GM dealer so this is the best I get with a cost of between $200-600. Does this sound normal for a computer "reset"
if that's what needs to be done?
darkstarmoto and anyone else who wants to know, according to a phone call to GM there is not an override button in this vehicle(2009) the cable has to be disconnected from the trans to move in neutral as rbarrios stated. Will post an update after the final diagnosis is made. THX!

IF they are 'replacing' the ECU that cost is about right, if they are simply 'resetting' the ECU that only involves removing the battery positive terminal for a few minutes and replacing it....which takes..well a minute.

Did something go wrong when trying to jump start that it wasn't successful (like touched the wrong terminals at the jumper posts)? Because that will/can mess up the ignition and or ECU.

this is getting ridiculous. the shop is just getting someone in to look at the computer issue they claim is "fried". i don't think anything went wrong with the jump, i had a neighbor helping me and I assume he hooked up to the right post.

will the car start if the ecu needs replacing? it is starting it just won't move out of park and the power door locks and interior lights don't work, haven't checked much else.
