I'm trying to access the exterior door handle on a 2016 500X, driver's side. I have the inside door panel off, although I still need to disconnect the wiring and cables. Before I go any further, the videos I've found so far show a secondary membrane-type lining that can be cut to access the exterior door handle from the inside of the door. The secondary lining between the door and the removed inside panel on my car is solid (probably thin metal). Does it pry off?
