Being a curious George I went out to test mine... my hood is always up in the the garage(so the mice wont build a nest on the SC) so I pulled fuse #26. Damn the fob dosent work any more.... but the car does pick it up as I can hear it clicking trying to open the doors. Insert key and turn, driver door unlocks fine. It does not unlock the passenger door or hatch.
With the fuse in and using the key it does unlock everything....

So it seems that the OP does have another problem if his key will not unlock the door...
