Released by Lenovo in October 2015. Identified by model number ZA0H0022US.
Here is a link to the service manual for your Yoga.
Scroll to p.84 to view the necessary pre-requisite steps and then the procedure to replace the USB and volume key module.
On p.30 item #17 you'll find the part number for the module, - 5F78C03560. (I think this is the correct one. As there are 2 numbers in the parts list check on your USB/Volume button module to verify which number is correct)
If you search online using the part number only, you'll find suppliers of the part.
Here is a link to just one supplier. It is not a recommendation to use them. It is shown to give an idea of the cost of the part. There are others that may suit you better.
Hopefully this is of some help
