I'm trying to remove the headrest from one of my 2nd row seats in my 2010 Explorer so I can properly install my Granddaughters carseat. The manual says to insert a thin pointed object like a paperclip into the holes of each head guide and lift up & it should come off. I've tried doing this multiple times with different people helping me & have had no luck. The ends of the paperclip dont seem to go in very far & the head rest doesn't move. If anyone has any experience with this your help will be much appreciated! Thank you!
