Non start and ignition switch problem

The boxster pre 2004 suffers with a problem ignition switch. The problem I have is the car will not start and the ignition key barrel is not sitting in its required position. I have been unable to lock the car remotely, which I understand is due to the ignition switch. I jumped started the car recently as it had been left for 3-4 days and it started without no hesitation, went back the next day and the battery was completely flat only flashing some dash lights. I put a trickle feed on the car for 3 hours and still nothing. Is this a cause of the ignition switch staying live. Your input would be very much appreciated
