Sorry for the late reply.
Could you please tell us just some of the key not go on or none of them?
You can go to the Settings--factory settings--others to make sure the key light option is selected.
if possible, would you mind take a short video, upload it to youtube or other video webiste, then send the link to us?
We will help you check and try to provide you positive solution.
