Missing keys on my keyboard

[kovalski]

Hello.
I recently lost a couple of keys on my keyboard on on this laptop Acer Aspire E15 https://productz.com/en/acer-aspire-e-15/p/lEbY4 laptop. You can see it in this picture:

Is there any way I can buy only the missing keys or do I have to buy the whole keyboard? Also, where can I buy these keys if it's possible?
