Well, I've had the same issue and in addition to replace it, I have also bought some pointer rubber top covers for my keyboard. Those are very useful and cool. You can search out for them into your local stores but I've personally bought those from Aliexpress. In addition, if you will decide for a purchase from Aliexpress, I strongly recommend using Ali tools. This tool will automatically find the best offer from verified sellers. In case you'll need, you can find more information by the link. Good luck ! ))
