I have the skylake precision 5510; it also has the keyboard debounce issue, and it hasn't been fixed. Contacted Dell, had the keyboard replaced but that hasn't helped. I don't have faith in their ability to fix this - it's been an issue going back all the way to 2009 and affects multiple models (latitude, inspiron, xps, precision)
Used an external keyboard for the first few months, so money back is not an option anymore. Terrible experience!
