Technical doblo cant seem to be locked fully

[johndoblo]

hi all, am new to the forum as i just purchased a new 2014 1.3d doblo cargo and the problem i seem to have is that if the window is open or was broken the doors including the back doors can be opened from inside via the push button at the door handle, i have read the booklet and it does not explain how to resolve this issue. its the bottom of the range cargo with a key for opening/closing and has no remote keys for deadlocking etc. any help on how to stop this function or change this setup would be great, thanks in advance
