BA-BF some au- to change central locking remote from single lock to double lock action when pressing remote -

close all doors -push and hold lock and unlock buttons on remote at the same time, for extended time until blinkers flash again - test remote operation -same again to restore original function

Done this to my car awhile ago, sometimes i find it a pain when only unlock once then walk to the passengers door and try and get in lol.

then dont set it this way or carry remote to passenger side !

stops someone uninvited jumping in passenger side in carpark while you or the woman in your life is getting in drivers side and knocking off your handbag from passenger seat etc.......................
