Thank you Tigerfish, an explanation that makes sense. There are obviousy a lot of owners out there who don't know why it is needed. It would, as Purvesh humourously stated, make it easier to steal, not actually so funny. Lexus should consider making the SHIFT LOCK key operaed as the boot lid can be. Just a thought to improve security.
Lexus, if you do it then i want paying for the idea!!!
