I wouldn't want to try this but, ....couldn't you just get a wedge of wood (like a door stop/wedge) and gently push it between the front window glass & the rubber. Hopefully widening the gap just enough for you to poke a stick (or something else suitable) inside to hit the door lock/unlock button?
Not sure if that would work tbh & really wouldn't want you to damage the window seal or window but just thought I'd put it out there.
