Ford Windstar Power Door Lock Replacement

Hi!

My friend owns a Ford Windstar, model year 2002, which he purchased from a German dealer as a vehicle registered in Germany.
As is common with American cars, all the doors lock immediately after the car starts. Because he often drives short distances, this is very annoying. Once, on vacation, he was standing next to his car with the key in the ignition when the central locking system suddenly locked the car by itself...

He would have liked to reprogram it. However, the Ford people say that it is not предусмотрено in the program, which I don't believe. I've already searched the internet and can't find any advice. Does anyone know how to do it?

Best regards,
Uwe.
