How do open your car door without keys and rolled up windows?
You best bet is to call a locksmith!!! There are several different ways to break int.....i mean get your car unlocked :) If the car uses a certain type of locking system, you can use a coathook to lift the lock lever (if it is the kind that has a vertical or up/down lock you can see near the window). Otherwise, it is probably a horizontal or side-to-side locking system, in which you will probably need a slim Jim. If you don't know what a slim Jim is, Google it and it will be more explanatory than i can be without pictures. The only other conventional method is probably the most simple... Your local locksmith will probably use a number of tools to pry open the top of you car's door. This could be anything from a plastic wedge to a inflatable diaphragm that gives you enough room to use a rod through the door and push the unlock button or move the lock control.
Remember to call more than one locksmith to get an unlocking quote. Some locksmiths charge double compared to others.
Hope that is helpful.
WARNING: YOUR BEST BET IS TO CALL A LOCKSMITH. I HAVE HAD A FRIEND BREAK INTO HIS OWN CAR AND LEFT NASTY SCRATCH MARKS ON THE PAINT. BE CAREFUL AND DON'T DO SOMETHING THAT WILL COST YOU MORE MONEY IN REPAIRS.
