I have now given up on trying to re-solder the keyboard sensors IC back onto the ceramic substrate, after many attempts non would work.

By chance I found a company in the Czech Republic that will ship to the UK and they have the TESLA Hall sensors, DSM Components

So this MicroSwitch Keyboard might just make it back to working condition.
