Lexus 2003 lx470
 

The problem I have is when I pull the car key out from the ignition switch all the power goes off. Like door ajar ceiling lights door lock and unlock, central lock, remote unlock.
I have checked all the fuses in the engine compartment and both driver side and passenger side fuse boxes all ok. Can anyone help me where to find the fault??? I bought it second hand so am not sure if any modification was done to achieve this condition on purpose. Help me rectify it please 😞
