Anyone have had this problem?

Sometimes when I open the car, sit in, close doors and turn the ignition on it sounds like the doors get locked? I hear the doors "clicking" like it dose when I click on the remote..

If this is above 15kph then thats the anti-hijack

the doors get locked before I start the engine.. it looks like they lock when I put in the key..
