hi all Every time we unlock the car and start to put our daughter in to her car seat on the near side rear the car locks after 30seconds. i have worked out that the car does not know that this door is open, it does not appear on the dash as open or turn the interior lights on. All 3 other doors, bonnet a boot do indicate on the dash as to being open. The car does not lock after 30 seconds if any other door is open. Does any one know how the car knows the door opens and how to fix this? I am guessing it is not like old cars with little switches that the door pushes in to say it is closed as i can not find one!! any help apreciated as one day i am going to lock my keys in the car!!! Thank you.
