Help, somehow disabled keyless entry / exit.

I have somehow managed to disable the keyless entry and exit on my 2005 Laguna.

I have done this I think, using various permutations of button presses on the remote and the locking button, start button and right hand stalk button.

Before anyone asks, keyless start still works. Its not the door sensor because keyless lock is also not working.

And for info, I was trying to disable selective unlocking in a similar manner to my Vauxhall which is done using a combination of the fob and the unlock button in the car.

And yes, I am an **** !

Help.
