sry about my english ,but you can use a really thin stick and long, approximately 90 centimetres then bend the top and put it through ur side window [around rubber that is used to protect rain] behind door handle , then try to move until the top ,which you bend it , touches and seems amost lock the metal stick inside ,next push forward strongely and the door will be opened ,but It might damage ur car .
