Hi Alan,
How are you trying to contact Vaio Support? You need Vaio Support - not Sony Support!
Try customersupport.en@vaio-link.com or telephone +44 870 240 2408 (Mon to Fri 0800 - 1800 BST) You will need to be within warranty and have the Serial Number of your Vaio available.
However, I am not sure broken keys will be covered by your warranty and you may have to pay for the repair.
As this is a fairly new model, there may not be third party keyboards available yet - you will have to Google or contact Vaio Support.
