Use this guide to replace or remove the keyboard on a Lenovo IdeaPad S340-15IWL laptop.
If your device is not registering keyboard clicks, the letters are not appearing on the screen, or your keys stick, it may indicate that your keyboard needs to be replaced or cleaned.
Make sure to consult the troubleshooting page before beginning the replacement as there is a chance that your keys may be obstructed, your drivers may be damaged, or the keyboard settings may have been changed.
Ensure that there is no food or liquids nearby while conducting the repair because your computer’s internal components will be exposed.

I would say that the best repair for a keyboard replacement on this laptop is to replace the entire top cover with the keyboard attached to the plastic pegs and top cover assembly.
I've done a lot of these for quite a few customers and they always come back complaining that the keyboard was bouncy after replacement.
Well, that would be because there are no screws to bolt the laptop to the chassis, and where the complete machined part assembly of the top cover can give you a perfect repair.
Sure its more expensive and more work, but it will help the customer out the most in the long run. If you're doing this repair yourself, feel free to do the keyboard only, but if you're doing it professionally for a client; Get a complete top cover assembly.
Hi
Does anyone have a link to purchase a reliable replacement parts for the keyboard/top cover?
Thanks for the guide...it proved very helpful in cleaning out the keyboard. My wife seemed to think the laptop sitting on the kitchen counter while reading a recipe was a great idea, until the sauce landed on the keyboard. Next time I hope she sticks with the tablet. Hopefully it won't be to bouncy without the plastic supports. There's probably enough plastic left to use a soldering iron and melt some of the pegs to offer more strength.
