2015 C Key Fob help

Folks,
I've searched this forum but can't seem to find the info I need. I just bought a used 2015 C to replace my 2006. It came with only one key. I want to buy another. I have the Techstream swr and am tech savvy. However, how do I know if I have an H or G chip, or no chip? The numbers inside the key fob are just HQ12BDM. I seen no H or G anywhere.
1. Does this mean I don't have or need an H or G chip key/fob?
2. If not, how do I find out which I have?
I'm new to the Gen 3 so I really could use some help.

Lastly, anybody in the Lynchburg VA area want to buy an '06 for parts? Engine clacking and the I believe the traction battery is done. Interior, Body and running gear excellent. Cat is good.

Thanks for the responses.
I have the techstream software and dongle. I just need to determine if I have a G,H, or no chip fob before I order. I'm hoping the software can detect the type of chip (which is actually the transmitter frequency) of the original key. I'm betting on the G, which is 315 Mhz. That's pretty common and what most tire pressure sensors use. But the only way to be sure is to detect it with an analyzer.
