Gosh, DO NOT PRY ON THE DOORS OR WINDOWS! I see that way too often and it breaks windows, scratches paint, and even dents the body/door. There is an EASY way to get in your car with very little work and no damage at all. Fill up a gallon milk jug with hot water. You can use straight hot water from the tap. Slowly pour the water into the door seam where ice has formed and glued the door to the body. In just a few minutes the ice melts and the door opens right up.
Are your windows glazed with a thick coating of ice? Gosh, don't pound and chip, you can crack the glass. Car windows are tempered so you can use the same hot water trick with no problems. Pour the hot water on your windows and the ice melts right off. Very little work, and no frustration. Keep a gallon jug at work in your locker or by your desk and your coworkers will be amazed at how fast you are in and gone while they struggle away.
