hi all, I'm thinking of getting a used MK3 but have a query. I currently have a MK1 which I will occasionally sleep overnight in when working away from home. I simply lock the car from inside using the keys and as it has no alarm, that's fine. However, how does the alarm system on the MK3 work? I recall an old vehicle I had years ago that I left the kids in and locked it from outside while I went I to a shop. What happened was the kids triggered the sensor inside and set off the alarm. So I'm concerned that I won't be able to lock my new MK3 jazz when I'm inside it??
