My wife has a 306 with the keypad style immobiliser on the centre console in frontof the gearstick.
We went on holiday for a fortnight and, as usual, the battery was flat as a pancake so when she tried the ignition the alarm went off. This has happened before.
I got it jump started but now, whenever a door is opened the alarm goes off and it is driving me nuts. I do not know the default code for the car as we bought it second hand and have no docs. We did have a new security unit fitted a year or so ago because after a repair we did not know the code that had been punched into the old one. Anybody got any ideas on what I need to do to sort it out?
