coat hangers are pretty handy for getting in to the car without breaking the seals...
but theres a million and one tricks best option is the coat hanger if not , locksmith.
also if yo going to break into the car... the small glass on the rear side door is the eazysist but i over just cut tennis balls in half and force it in at the corner of the window , if done right the window shatters and no glass moves
also you can just get a nail or a knife and push it into the window and it will give way...
you could break the seat o the bottom section of the window and use a hook to open it but again the first opion is the best one
