It can be pretty easy to do.
You'll need a bright flash light and a small flat head screw driver.
Turn on your flash light and shine it directly onto the dials, take your small screw driver and push the dial to one side or the other, usally push it to the left. 
Yes, you won't have a lot of room to move it, but you should have just enough to see a line, or a groove. If you don't see a groove turn the dial to another number until you are able to see a line, or groove.
When you see a groove you are on the correct number, then do the same to the other ones, then push the button to open it up.
Example. (0)(0)(0)     (0)(2)-(0)     (1)-(2)-(0)     (1)-(2)-(3)-
Good luck.

pull seat back as far as it wil go then take all the screws out of the door pannel and then at the edge of the door nearest the pillar wedge the pannel so u can get ur fingers behind then pull hard mooving down then along the bottom pulling , now u have com to the bit thats trapped behind the dash. dont worry from the bottom corner facing the pillar lift the door card upwardsthe door card will part from the window trim and part from behind the dash in a shearing motion two new clips will be requred but no major damage

You could always break a window! You could try and wedge one of the windows open enough to stick a coat hanger or something in to try and unlock the passenger side. Good luck
