'94 Galant door issues
 

Hey there. I'm a Mitsubishi newb here but I just inherited my late Grandad's 1994 Galant. I'm working on it but issues have arisen. Mainly the rear passenger door. I don't know what it is but whatever the case the door is completely jammed and there's no getting it open. I'm trying to figure out if it's this ancient security system or what. Any theories or ideas?
