Okay, if I understand you, the passenger door will not open and it is not locked. The likely issue is in the lock actuator itself. There are linkages and levers that move as you lock/unlock the door. It sounds like one of those has broken and is not allowing the door handle to release the latch.
It could be as simple as removing the door panel and spraying the unit with some lube to free up the parts. Or you may have to replace the actual lock/latch.
Either way you will need to access the latch itself to determine the problem.
