Driver side, can lock all doors when turn the key, but when try to unlock it only unlock driver door.... it this normal?

on Passenger side it can lock and unlock all doors when turn the keys...

 

From the drivers door it only unlocks itself - that's a "feature". You either hold the key for a couple seconds, or you twist the key a 2nd time (can't remember which).

 

I try both technique but doesnt work ...

 

straight from the owners manual...

All doors can be locked from the
outside by using the key in either
front door. To unlock only the driver's
door from the outside, insert the key
in the driver's door lock, turn the key
and release it. If you turn the key
and hold it, all doors will unlock. All
four doors will unlock when you
unlock the passenger's door with the
key.

if you have issues, the multiplex unit may be going south on ya.
