Need help getting a 2nd key

[rawr]

I just bought a used 2010 Mazda 5. We're pretty happy with it so far, although not so happy that the owner had only key to hand over. We were even less happy when we found out how much it would cost to get a 2nd key made! Anyway, I've done my reading, and would like to try and find a compatible switchblade-style key online. From what I understand, it seems like I need to make sure I match the FCC ID. I took the key apart, and can't find anything resembling any of the FCC IDs that are out there.

This is what I found:

Stamped into the black plastic on the inside, next to the battery:
>PA-GF50<

On the green circuit board, in white letters (next to what looks like a Mitsubishi logo?):
JX331BA88
02B

On a black chip on the board, in white letters:
MH86O (or 0?)
-DM98
949E

I even found this, etched onto a small silver component (so small, I had to use a macro lens to read it):
500P

Googling these codes don't seem to come up with anything useful. Is my remote really that unique? Is it because it's a Canadian car? It looks exactly like the photos of the other keys I've seen out there.

Any help would be appreciated.

I found my ID on the case, it was behind the blade, in that spot where the switch-blade folds into..

Wow, I don't how I missed it! For future reference, it was in very small yellow writing on the remote half. After I separated the two pieces, I could see it on the newly uncovered side that was facing the key half.

Thanks for your help.
