SIDE  DOOR  CENTRAL   LOCKING  - (  Lubrication required  )

REMOTE  CENTRAL  LOCKING  NOT  WORKING  ON YOUR  CABIN DOOR   ???

This  is  an easy  Fix  and part of  normal maintenance  required which is  just  CRC 
On the edge of  your cabin door you will see 2  pins  as pictured  ( this is the contacts  for central locking ) 
And  after a while  they stick with usage  and dont move  freely .
so all you do is undo  the  2  philips  screws  and it will slide  out   ,( making sure  you dont  turn it upside  down when you put it  back  )
on the back  are two pins  spray each one  with crc  from the back and  move  pins  in and out from front and  back  to make sure sliding freely
put it  back into place  and  screw  the  2  philips  screws back in ......  and you are  then all sorted 

PLEASE  REMEMBER  TO NEVER  ....  use the remote key fob to try and unlock door and at the same time try to open the cabin door
otherwise you will break the  lock .......
