Fcc id?

[robtemp]

I'm looking to purchase a spare advanced smart key for my 2007 Mazda CX9 GT. What I'm having trouble with is finding out what the FCC ID is of my smart key. Where is this number located? It's not on the front or back of the credit card key. I've opened up the key case to look at the circuit board inside and there's no number similar to BGBX..... There's a JX331BA... # but I don't think that's it.

Dealer says he can't pull the ID based on the VIN only so that doesn't seem like an option.

Please help.

Thanks,
Rob
