Repair of FFC connector mount for a Lenovo Yoga 2 13" mainboard?

Is it possible to replace a mount / bracket / holder for the Flexible Flat Cable connector of the keyboard port of an Lenovo Yoga 2 13" laptop mainboard - because it was broken? Since then 6 keys of the keyboard are not working.

If it’s possible - where to order that part? I don’t even know the exact term or identifier for it. What’s the exact term for this part?

Anyway, I managed to glue the piece together again and it looks as it does it’s job by applying pressure between the port and the FFC contacts, but still 6 keys are not working. The initial reason for opening the laptop and touching the plastic mount / holder and breaking it because of wrong handling, was, that there went some black tea (without sugar) over and in the keyboard and I wanted to clean it. But all the keyboard backlights are working after a drying break of 3 weeks and all the other keys as well. Do you think the reason could be the fluid damage, still? The non working keys are NOT the keys where the fluid was gone. The non working keys are G, H, Ä, <, ArrowUp (german layout) which are quite DISTRIBUTED across the keyboard. Is there a way to check if those keys are dependend on the same contact of the FFC, that may not have be enough pressure from the broken (but glued) plastic mount / holder / bracket?

Thanks in advance for ANY feedback!
