oval, i had this problem twice, i did nt try t destroy t lock but its one of t two options. if you mange to remove t door card you ll still have too destroy t lock too open t door, what i done was i took ff t back door hung it from t roof, that allowed me room too cutt striker bar not easy either, but now youll have too get a new striker bar also, basically what happens is a plastic part in t lock breaks yes thats what opens t door a bit of plastic and i mean a bit its tiny, and also try and get t replacement from t exact year of vehicle, i did nt and had too make one out t two, personally i d say follow t thread on how too destroy t lock its what i d try t next time first.
