How do you replace the trunk release locking mechanism for a 2003 ford focus?

To replace the trunk release locking mechanism on a 2003 Ford Focus, first, ensure the vehicle is off and disconnect the negative battery terminal. Remove the trunk interior trim panel to access the locking mechanism; this may involve unscrewing bolts or clips. Disconnect the wiring harness from the old mechanism and remove it, then install the new mechanism by reversing the steps, reconnecting the wiring harness, and securing the trim panel back in place.
