oh, some cars that have electric locking systems have a sensor in the driver side door lock, so, when you push the lock down on the driver door, it makes all the doors lock, so if this sensor is malfunctioning, it can cause the doors to lock and unlock unexpectedly, i’ve had this happen before, what you can do, and this can be done at home though it is easier to have a dealer do it(i’d do it myself), what you can do is take the door apart and either remover the sensor from the lock device in the door, if you can find it, note this will bypass the sensor completely so the doors will not auto lock with the driver door, OR, just by a new lock and install it, or have the dealer do it, either way
