A hackerspace is a place where hackers meet to do hardware or software hacking projects, like Umea Hackerspace in Sweden (they happen to run a GNUsocial instance) https://social.umeahackerspace.se/ . In many cities there are hackerspaces, and these ppl may have an idea to help you. Perhaps they have some old unused USB keyboards and can give you one. --- Another idea may be to look at eBay for a replacement keyboard. I once bought an original spare keyboard for my notebook for €15. --- Yet another idea is to order a replacement keyboard at a spare parts dealer like this http://www.ipc-computer.es/piezas-de-repuesto/tecladoen
