We're taxing my memory in terms of the exact sequence of steps, but try this:
Turn car on w/out engine on (press start button twice w/out pressing brake).
Press and hold the lock button on driver's door for ~5 seconds.
Start the car and drive it - see if it worked.
If that didn't work, try doing the same thing in ACC mode (press the start button only once w/out brake).
If that doesn't work, try the above but press the Unlock button.
Pretty sure its something like that.
