lock back itself even if back door has been opened

Hi all,

The centralised locking system of my T6 locks itself back up after 30 seconds if no doors have been opened for security reasons. since I replaced the back door, even if I opened that door, the car locks itself up after 30s. I only replaced the door body and kept the harness and lock. when I opened the other doors, it acknowledges to the CPU and the locking system stays opened as usual.

is there anybody who knows how the signal is given to the CPU. is it a built-in switch within the lock giving a status open/not open signal the CPU? or do we need to re teach the CPU that a new door has been put in?

any ideas guys?
