Civic Drivers Door Lock Relocks Itself

My Granddaughter has a 2006 Honda Civic that can be locked with a key but not unlocked with a key. The only way the drivers door can be unlocked is by using the rocker switch to unlock it & pulling the handle down within a half a second. After that it relocks itself. The mechanical inside lock next to the door opening lever doesnt work either. Might anyone know what might be wrong, or broken?
