1999 LS Programming Power Locks

I just bought a 99 Malibu LS. It is fully loaded except leather. Anyway.....the locks don't automatically lock and unlock. Most newer GM cars have a procedure to program the locks in a way that you can turn that feature off. My car didn't have the owners manual. So if the procedure exists....I don't know how to do it.

Is this possible??? If so, can someone tell me how to do it??? Thank you ahead of time.
