I'm currently unable to enter my Jeep, via the driver side door. It's locked, and won't unlock. This happened to the passenger side door about a year or two ago. I managed to get it fixed, but it was a huge pita, without the proper tools. With that in mind, I quick screwing with it and ordered the six dollar tool, to make getting the window crank handle off and on a bit less of a pita. Until then, it'll sit.
