I just completed a 2009 Mazda cx-9 and the customer uses her autoheadlight feature . The problem is that when they exit the vehicle at night the doors will not lock until it times out .Is there a way to allow the lock function to work with the auto system still on. I have the locks wired to the PURPLE / white single wire with a 1k resistor,and the factory alarm is bypassed using the keysense.

Use lt.green to arm/disarm & lock/unlock, same connector as the PURPLE / white. Unlock/Disarm with (-). Lock/Arm with (-) through 1K ohm. >0.8sec pulse will unlock all doors at once.
