My dad can't get the passenger door to open on his '97 Hyundai Coupe. It's impossible to unlock the passenger door, both with the key and the switch on the inside of the door - the switch and key move as you'd expect and feel 'positive' enough, but neither the interior or exterior handle will open the door. Even the central locking still appears to be working (the passenger door lock switch toggles when you activate the one on the driver's door) but the door just ignores the position of the switch.
I've had a mooch, but it appears that to take off the door trim, you have to remove six screws that (you guessed it) you can only get at when the door is open. Short of destroying the interior door trim, is there any way to get the door to open?
