Hey, I have a 2015 Ford Taurus and for some reason when I lock my doors they unlock and I have to lock all doors by hand. Can someone please let me know how to stop this from happening. Also, for some reason my lock button on the keyfob doesn't work so I press the inside lock to lock it.

 

There's a switch that is activated by the gear selector that locks the doors when put in drive. I bet it is faulty or a connection is loose. I think you have to remove steering wheel. Remove neg batt post, the steering wheel and the column cover. The switch should be around the D position behind the gear selector. I don't know if you could just try Low gear to see if it locks. If it does, that could be an adjustment.
