[K.S.H]

Phone the Police, they have a kit to get into most cars or try yourself with something like a coat hanger in 1 of 2 ways
1 - pull the button up if its on the top of the door moulding
2 - you got to try and get hold of the metal rod that the interior handle is fastened too, put a slight hook on the coat hanger/wire and go straight down the inside of the door (down the side of the window, just force it past the rubber seal)to the same depth or just lower than the lock, rotate 90 degrees and pull upwards and hope you grab it, keep trying till you get hold of it, you might end up bending the rod but better having to straighten this than replace a window
