Programming sequence for automatic door lock

Hi all,

I've bought myself a XJ-6 X300 -96.
The car has the (bad) habit of locking the doors when I swtich in to drive..
I know that this is a feature, however in Sweden we never drive with our doors locked.
I used to have a Ford Explorer, and I know that this feature is possible to switch on and off by programming the car.. For the Explorer it was a matter of turning the ignition key a numer of times and pressing certain buttons in the car in a pre-determined sequence..
Does anyone here have the programming sequences for this features?

Thanks in advance!
