I have a 2007 Malibu V6. I do not remove any fuses as I am able to turn the key to the off position. (Almost to the off position) I cannot remove the key, but everything is turned off.
If the 2005 is the same body style as 2007 Malibu you will have no steering wheel lock.
Try turning your key to the on position, shift to neutral and then turn the as far as it will go toward the off position. If everything electrical is dead you are good to go.
