i've a quistion i've seen that option allready in usa and UK/JDM ludes
this option to lock down you're door from the inside
stole pics from si imports

have anyone a diagram how it works and what parts you need for it?
also on the pic from si imports you see the passanger had only a switch for the window
here in Netherlands we don't have the switch to lock the door but we have a place to put one in and also on the passanger side..
and if you lock on driver side the door.. wil also lock the passanger side??
thanks Ferdie
