If you have fold down rear seats then you are OK.
Remove the rear deck cover, oh whatever they call it.
It is glued in so need to give it firm tug. Then unclip the center stop light wire and remove.
There is a large speaker hole that was never used on the contour. You will be able to reach through and release the fold down seats.
Once you get in I don't know what to do. If you can get at the switch that will allow you to use the cable release then you are saved.
