Will i need the win10 activation key? [duplicate]

The situation is that there’re some problems with booting any system on my laptop(cannot boot any system at all), it was preinstalled with win10 and now it’s not booting, I want to format the whole ssd,will win10 after reinstalling find the activation key automatically or I’ll need to enter the activation key? Found some information that windows will not be able to find the key after CPU replacement and ssd may be freely changed but still not sure about this.
