2012 LTD R rear door stopped opening on 2nd pull of front door handle & 1A key is within 3 fee of door. All doors lock when pressing the exterior bump of F door handle.
It used to be that when I approached the locked vehicle, first pull on L Front door handle unlocked the L front door, and the second pull then unlocked the rear door. (that is one of the advantages of the 1A Intelligent Access key)
Could this have anything to do with the R Rear door ajar sensor?
