206 Xr Brain Malfunction

I have the 2002 model 206 Xr car, the key opens but does not close the doors due to auto lock failure

I took it to the mechanic, checked all the doors and luggage

finally the fault
He said that the Insurance Table also had a box that says SİEMENS.

already attached the central lock from the outside to the box

I think there is a malfunction in the role, it knocks back the doors that are closing (reopening)

He said that the malfunction is in this, I decided to have it repaired.

this piece said it only directs the door and signals, the repairman would like to have it repaired if possible. do you think i have it repaired

can you help me*

When looking for the fault, the cable was cut, it made me bored, are you the same fault? Do you have the doors opening but not closing?
