I have a 2016 ford focus se hatch and the rear button on the car doesn't work.. used to work and just stopped one day a couple of times it worked but you had to press hard. it not hard to press the button and if I press it now hard or easy nothing happens... my key and interior trunk button still works. I use my trunk almost every day and it's just a pain to get out my keys again instead of being able to press the button on the back of the car. any ideas on what went wrong and how to fix it? thanks!
