hi i have wondered the same thing. there are videos online which feature Honda/Acura accords in the US, which you can change the door locking modes by turning on the ignition, then pressing and holding the master lock button, till it click 2 or three time.
i haven't tried it yet myself, because these videos, being American, are all automatics, and to reset to default they mention being in park with your foot on the brake, etc..
i do know that the US Honda/Acura and Euro Honda are extremely similar in a lot of ways. Might be worth you looking into.
