I would like to find a way to source the NFC chip that is in the FOB and put in my cell phone case. IIRC, the key fob has two components when you open it up. It has the circuit board/battery which operates the button functions and it has a chip which is glued to the bottom half of the case. I believe this is the chip that is registered with the vehicle for keyless operation.

I would like to find the source of this chip and buy it so I can program it like a fob and put it in my cell phone case or wallet to alleviate the need to carry the FOB.

On early Honda keys, the transmitter was a T5 chip and you could buy them for a dollar or two and get them programmed. I believe the same thing can happen here.

If anyone has a fob that they would like to send me, even if it doesn't work, I would be interested in doing some experiments.

If anyone is able to find the manufacturer of the chip, let me know. Below is the bottom of the FOB case. Perhaps someone can share with me their case so we can try to figure out what might be a part number.

Buy a fob on ebay - best bet right there.

Super interested in this. I hate GMs fob. I miss my RX8 key. It was a credit card basically. I'd rather have a normal key and have to use it in the ignition over this stupid thing.

Remote call and drive (automated chaffeur) will require some sort of interface like this. I believe it's in the works.

As shown in the OP's photo, CMIIT = https://en.wikipedia.org/wiki/Ministry_of_Industry_and_Information_Technology.

That product registration number (similar to FCC product registration number) can probably be used to identify the manufacturer.

EDIT:
FCC ID HYQ4EA is registered as a fob for Camaro and Malibu and they can be purchased here:

More details are available from the FCC database. https://www.fcc.gov/oet/ea/fccid.
From the OP's photo the Grantee code = HYQ and the Product code = 4EA
The FCC database confirms that, as marked on the fob, it is manufactured by DENSO of Japan. And, based on photos in the FCC database, the same circuit board is used in quite a few different Chevy fobs and can probably be found at a junk yard.
