rob have you tried opening the car from the boot? also if the doesn't open the doors, hold the key in the open position until all the windows open, then put the key in the ignition but dont open the drivers door as the alarm will go off, press the unlock doors button then open the door. i had this problem with mine and it was the only way i could get in the car without the alarm going off. a simple recode and reset in vagcom and all is well
