HELP! Locked out, key fob broken, key door lock mechanism broken

[ike301]

ok, so worst case scenario has happened.

1. key fob remote battery dead for over 6 months.
2. door lock mechanism broken - i cant manually arm/disarm or unlock doors.
3. can't unlock doors using a wire and manually pulling on door latch b/c latch is double locked when armed.

dealer wants to break window, climb in, hopefully unarm the car by cranking with the key (he hope by cranking it with the key, it will disarm the car). then replace the window and then replace the door mechanism.

ok, hoodlums. need you advice how to break into my car CHEAPLY.

help!!!
