Your are absolutely right sir. My Bad, I was thinking in the perspective of the Punto which does not have a boot Open button on the remote. So one has to open the driver door to use the Boot Open latch (In which case the driver door will lock on it own) or use the Key manually to open the Boot door. Again, for a Linea, it's possible to screw up i guess. In either case, i absolutely agree that one has to carry the spare key atleast when doing long drives (And make sure it is in a safe place in the pocket and not a bag inside the car ).
