2003 Malibu doors lock in gear but do not unlock when put in park why is it programmed through the radio?

In a 2003 Malibu, the door locks are programmed to engage when the vehicle is in gear for safety, preventing accidental exits while driving. However, if the doors do not unlock when the car is shifted into park, it could be due to a malfunction in the central locking system or a programming issue. The radio may play a role in controlling the door lock functions, as some models integrate the locking system with the vehicle's audio system for convenience features. Checking the vehicle's manual or consulting a professional may help resolve the issue.
