Hi I had this, but mine is a SW model and you have to check that the two boot doors are closed too.
ei the central locking will not work if the top window boot is open. check it by just pulling on the winscreen wiper on the back window. if it is open this is why the central locking will not work. It is a safe guard so you do not walk away for the car even if you cannot see the boot is open.
