Repair or replace keyboard cover wire

Hi,

My son has a Surface Pro 8 with a genuine Microsoft cover keyboard. The keyboard has stopped working, on investigation I have confirmed it is the ribbon cable that goes around the hinge and connects to the edge of the tablet.

I understand that this is a common problem so Microsoft are pushing poor quality products on our schools.

Cut to the chase has anyone successfully repaired or replaced the cable?

I suspect I need to completely remove the fabric outer to find the clips but it would be useful if the ribbon cable could be push in.

Thanks in advance
