Bruce-
I can't think of any reason for a repairer to access the hood latch system in this case. For a fix, I suggest first getting your head under the dash and inspecting the release handle. Then seeing if there's any way to remove the grill from the front [this will allow manual latch release]. As a next resort, crawl under the front of the car, remove the bottom engine cover [~15 screws] and look at the cable, but it's unlikely anything would be apparent. Last resort is the dealer, but note that they may have a quick fix!
