Central Lock problem.

[powerboat]

1999 A6 Q.
Central locking system.
2-3 minutes after I unlock the car, it locks itself if not started.
I was lucky the first time it happened, the keys were in my pocket...
Is this normal? If not, how to fix?
Thank you.

Normal - believe it is an anti-theft feature. Happened to me a couple of times a well

Mine does it as well. Luckily it won't lock if the keys are in the ignition.

It is to prevent the car from staying unlocked if you hit unlock by mistake while walking away from the car. If no doors are opened after a period of time, the car will re-lock itself.

Just remember where your keys are when you lock the car but are still getting stuff out of the trunk!
