General Central lock issue

[Bhagwan]

I am experiencing a problem in central locking system of my Fiat, Linea, Emotion, 2010, Petrol.

Problem description: All four door are working properly with car remote key. But there is locking issue while using manual key.
Scenario 1: When all doors locked. I insert key in driver's door key socket, only driver's door will open.

Scenario 2: When all doors unlocked. In this case I can lock only driver's door, not all the doors with manual key locking.

Can someone help me to understand the issue.

Hi and welcome

Your Linea is probably a model based on the 188 punto, these cars are now rare here in the UK

But the problem is likely to be a common one..

I suspect the keylock (drivers door) is not sending the 'locking signal' to the other doors

Using the Remote is using the 'BodyComputer' To drive ALL the locks

Do you have a keylock on the passenger door?
