Nah, not really any way to repair that kind of damage. You just gotta swap the KB out. It's not usually all that hard to do. If the machine's under warranty, and you're sure you didn't spill anything, then you can probably send it back to the manufacturer for repair. (They check for water damage if it's not covered by the warranty, but things do break, so... yeah.)
There appears to be a couple different "DV6" models, they might not all have the same keyboard, but DV6 keyboards are running about $20 USD ($24 NZD) here, so they shouldn't be too bad. You could always see if somebody in FS/FT would be willing to work as your proxy.
Scientific progress goes "Boink?"
