You need the little tool that came with the car (looks like an allen wrench, but is not an allen wrench). If you dont have the tool a long 1/4 extension will work too. You have to crawl in the back, and look at the sides of the headrest(can't remember if its the inside or outside side), you will see a small line composed of stitching. You have to insert said tool (or 1/4" extenision) where that line is. When you press down on the release tab with the tool/extension, you have to press down with the headrests at the same time. Hope this helps.
