When I used to get out of my Roomster the doors could be locked with a press of the lock button of the remote control.

This no longer works.

To lock the car I now need to either press the unlock button of the remote control key or before getting out of the car press the unlock button on the central console, then press the lock button of the remote control (from the outside of the car) .

Is there a fix for this problem please?

Sorry, I don't have a fix.

 

But do you have the same problem when using the other key?
