My girlfriend owns a Levono Yoga 3 14 and just recently the keyboard has stopped working. We bought it at Best Buy and considering their is a crack in the screen they can't do anything to fix it.
I have tried updating the driver for the keyboard, getting every update for Windows 10 updated, and even Factory reset the laptop to see if that would fix the problem. Also, I tried entering safe mode to see if for some magical reason that would at least get the keyboard to work and nothing. Another possiblity that I had thought of was the anti-virsus (AVG) was blocking the connection between the keyboard and the laptop so I removed it and it didn't help at all. This recently happened on my laptop so I figured I'd give it a shot.
The keyboard does light up when the laptop is initally turned on but none of the keys work after that. I'm able to connect a external keyboard to the laptop and use it that way but actually using the keyboard on the laptop I have had no success.
If anybody has had any problems light like this and has came up with a solution, please let me know.

Welcome to the forums Ser4!
I updated Lenovo Transition software but problem was still there. I stopped "ymc" service from Control Panel->Loca Services and keyboard was back to work! Remeber need to set "ymc" service Startup type to disabled so that the keyboard will continue to work after reboot.
Let us know how you get on.

I think I had the same problem, just for confirming, when you're in the BIOS it doesn't work either?
I sent my laptop back 2 times to lenovo before finding a solution myself. The first time they did a reset/update of the BIOS. But only 3 weeks after receiving it back, the keyboard stopped working again, we send it back again and they replaced the whole keyboard... I had my computer for one week and the keyboard stopped working again.
Before sending it again or asking for a new one, I checked all the drivers (as you did) and I found that they released a new BIOS update (for keyboard trouble apparently)
I hope it works for you too!!
