 My 2007 ford focus rear door also will not lock manually or with the remote. Report this issue on Safercar.gov This is a safety issue because our kids can just open the rear door because you have no ability to lock the door and/or use the child safety lock feature. This happened to my 2007 Focus and dealer asked for $500. Please report all car issues to the people who force the Auto companies we just bailed out to fix our cars.
