I had to get a new remote key made today for our Corsa, one of the two original keys was a bit faulty, and it's always best to have 2 good keys. It needs to be re-programmed from the diagnostics socket, which I thought was located below the heater-ventilation controls, behind a press-out black cover. However, I have removed the small plastic panel, and it is not there. Are any Members here aware of an alternate location for this socket please? From my brief perusal of the owners manual which came with the car, there is no reference to it. Thank you.
