The Isis Adventure

So I got the Isis open to find a real key. I live nearly 800 miles from the nearest non-virtual pyramid. What I am supposed to do with the real key? Hold on to it just in case I ever go travelling/wandering/on vacation?

Seriously, what's the other option? Throwing it away? Flushing down the toilet? I wouldn't do that.

Other option.....send it to me

If you're planning on doing the whole series of Isis puzzles, you'll need to collect the keys from the first four puzzles in order to make a valid claim as being the first to open Isis V - there's apparently a cash prize for being the first person to open the last puzzle in the series as long as you've opened the first four, first.

Thanks for the info about the entire puzzle series, and the necessity of the keys.
