open gas door without battery ( or keyfob problem)

[brainrain]

Hi everybody,

I want to know if it is possible to open gas door without battery or keyfob problem for unlock door.

on manual, I read this :

. Insert the mechanical key into the door lock
cylinder and turn it to the rear of the vehicle.

But when I use mechanical key, I just unlock the drive side door.

any ideas please ?

Thank you
