2015 Peugeot 3008 Central Locking

[BigStu09]

Hi all.
Brother has a 2015 peugeot 3008 and central locking has stopped working..all doors are unlocked.
Using key in door only locks drivers door and no way to lock other doors.
When pressing lock button on dash he can hear a click but nothing happens.
He has tried a bsi reset with no joy.
Anything else he should be looking at.
Thanks
