How to unlock the middle storage department? on 2008 Lexus GS450h

i have apparently locked the middle storage department that is between driver and passenger seat. how do i unlock or lock it?

PS. it could have broken but i think that is locked. no reason to think is broken other than the fact that its nor opening

With a key? What does the owners manual say? Or has a broken latch.
it does not have a key hole. it must have locked by pressing a combination of buttons probably.

i have the owners mannuals in a storage facility, which i think i should take back and look for solution.
Sorry, but yes the manual belongs in the car not storage.
