Here's a question for someone...
What happens if your away from home in your 172 cup and the key remote fails. You think bugger, i'll just have to use the old key in door method. However, when you open the car this way, the alarm goes off as soon as you open the door and you won't be able to switch it off as the remote isn't working. Will the alarm stop if you start the car, or will it not start because the immobiliser is armed?
See where i'm coming from? Or am i talking complete and utter cr*p!?
