Other 70 Problem: Difficult problem. doors wont open.

[gottobeg]

Hello.
I own a 2002 volvo v70. Yesterday as usual i locked the doors with a key (don´t have a remote) and today they would not open. The key turns nicely both ways but somehow it wont unlock the doors. from between the doors i tried pulling up the knobs with a string. the knobs moved up nicely but still nothing. then i tried pulling the handles with a wire but still no luck. there are also no other keyholes other than the driver door one. It seems that the doors are deadlocked and the pin might have come loose from the driver lock shaft so it wont turn. now i have ran out of ideas of what to do. for my disadvantage i have previously disconnected the driver main window mechanism. so even if i attach a key to the wire and turn the ignition on, i still can not lower any of the windows to get inside of the car. as i have studied and searched from the internet for hours i am starting to lose hope and it seems that my only option is to bust a window, remove the driver seat, rip off the driver door panel and somehow press the brass latch that will open the driver door. Is it possible that some of the fuses are bad and that´s why it wont open the driver door (to my understanding, the door should still open with a key, even if the deadbolt is activated) or are there any other methods of how i could get inside or just something that helps. i would not like to smash in a window i´m getting desperate.
