door locking problem

[_crazy_crazy_]

well i have a little problem in my 7 the door locking mechanism wasn\'t working properly and when i needed to transport the car i had to close the door and i did by closing it and then locking the door but now the door doesn\'t unlock .
i\'ve allready tried to disassemble the door and see if i could unlock it but it seems as the mechanism is jammed any ideas on how to open the door ? and by the way i don\'t have the key for that door since the last owner had a bit of stupid ingenuity and i have 3 different lock\'s in my car and i only have the ignition key so any ideas ?

thanks in advance

p.s. i forgot it\'s an 1987 fc n/a just in case the locks are different and it doesn\'t have for what i could see central locking
