Hi Ian .

Okay the key fob is ok, what problem you have is the chip in the key is not being recognized by the Immo will need a diagnostic scan tool to check what has malfunctioned with in the system.

What you could try first is the second key if you have one as the one you are using maybe faulty.

If the key does not work then you will need this checked by a dealer or you could use the mobile keysmith team . Please click here for locator .

Need further assistance then please get back to me .
