Dead lock warning

[ka4564]

Hi all hope someone can help
I keep getting a warning when I turn the ignition off saying ' check dead lock mechanism'
I assume somehow this has been activated - hence once locked from the outside anyone inside cannot get out!
I have referred to the owners manual which says to deactivate
Press the remote lock twice
Press the internal lock on door once ( which incidentally does nothing)
Insert key and lock twice
But to no avail I still have the dead lock activated :crazy

Hope you can help
