My passenger door wont open from the inside. I have a 2005 honda accord...
 

...coupe, I read the manuel? And there are no child locks on a coupe, what could be the problem The doors open fine from the outside.

90% says there is a break or a snag in the linkage connecting the inner door handle and the latching mechanism... if you are brave you could take the door panel off and look for it. Otherwise I suggest taking it to a dealership or body shop and ask them

sounds like the linkage to the latch mechanism dropped or completely broke......bring it to the dealer as it is most likely still under warranty....messing with it will void the warranty
