Hard to read the last three characters from one of my keys (no label on the other) but the information seems correct according to google...

FCC ID: HYQ12BZE
IC: 1551A-12BZE

Thank you for responding, That's the Fob's I purchased. I had a locksmith come out earlier to program them. Two hours later he finally gave up. So I have the Master that only works if in the key slot/ignition to crank. When he was programming the lock/unlock sequence it would work until he opened the door. Then no lock unlock, tells me that the FCC ID must be wrong. The place I bought them from asked for my VIN and said these was it.

FWIW, my FOB is for an 2004.

I've only owned my car for a week and one half so I'm certainly no expert around here. But then again I've had a chance to read the manual. How many keys did you have before this? I only got two key fobs with my car and I think that they are both master keys because I can open the trunk lock with them mechanically. Is it possible that the key that you have is a sub key?

My car only came with the master key in the first picture. The FCC id was long gone.

You might try going to a dealer and talking to the parts person. They should be able to give you the right part number using your VIN. Explain to them what you are trying to avoid the high cost of keys and they should be able to help you figure out the information you need to order aftermarket keys. Just a thought, worth a try.
