PDL has changed its program

[Ken1]

If my 7 year old recall is correct, when my 01"X" was new we had a method to program door locks so only driver door would unlock with one press of FOB and second press of Fob all locks would unlock. This has been the program for 6+ years but today when I press the FOB one time driver door unlock and then the other doors unlock.
How to reprogram PDL?

Thanks for your reply
