Drivers door lock

[Jimary]

I have a 1999 MA gas on the F53 chassis, and the keys I have don't work the drivers door. I have both keys for the side door and they both work. The side door and drivers door locks both have an "F" stamped on them, does that mean they use the same key? Any help would be appreaciated.
