All locking is one-way only, to reduce incidence of non-keyholding Simmies getting trapped in a room they are not meant to be in when you lock the door. Place with green arrow pointing in towards restricted area.  Sims will always be free to exit even while entry is restricted.

Hack does not work when the door is placed diagonally.  This is because when the door is placed diagonally, it actually becomes a different object.  I have decided not to offer the diagonal option for the time being because I can foresee various complications and cannot yet think of a very good way round them.  For similar reasons, the door may lose its settings or become unsynchronised between the two sides if you try to move it after setting up keyholders.

Suitable for all games as long as you realise they totally ignore the Maxis tests for door locking, and probably do not understand Pets.  For this reason these doors are not recommended for the main external door or for bathrooms as it does not run the Maxis code that deals with the arrival of visitors and bathroom privacy.

NB doors offer original range of colours, but do not use custom recolours made for their Maxis counterparts.
