Automatic Locking De-activation

Is it possible to de-activate the automatic locking feature after the vehicle has been parked for a time.
It would be very easy to leave the keys in the vehicle by mistake, then be unable to open the doors to retrieve them.

Yes. Instructions on how are in your owners manual. It has also been discussed in several posts.
