Sedoy, even with broken driver door handle,
did you try the "two key turn" method, as
noted below?
It looks & reads confusingly, but a "double turn"
should open other doors, manually.
Then, you can pop hood and connect batt. charger to
bring batt. back to life, hopefully. Your "mechanic"
does not sound too adroit, lol!

Opening and closing – via the door lock
Using the key
One turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the liftgate/
tailgate and the fuel filler door.
You can have an acknowledgment
signal set to confirm that the
vehicle is correctly closed.

Convenience operation
You can also operate the windows and
sliding/tilt sunroof via the door lock.
>
To open: with the door closed, turn
the key to the "Unlock" position and
hold it
>
To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to be sure that no one is inadvertently
injured. Releasing the key stops
the operation.<
Manual operation
(in the event of an electrical malfunction)
Turn the key to the extreme left or right
to unlock/lock the door.
