Ive just came home from a fairly long drive, running like a dream. Got back home parked up in my driveway, left the car running for about 30 seconds whilst i closed the gates then turned off the ignition. When i opened my door the siren was going off (like when you leave your lights on without the key) so i tried to put the key back in the ignition and it wouldnt go in? no dash lights are on, heaters etc wont work but the stereo will still turn on? and the keyfob wont work neither (it will unlock but not lock). am i just being dumb or does it sound like i have goosed something?
Thanks in advance
