2010 Legacy GT Key Replacement / China Blanks

I have looked high and low and couldn't find all the right information in the same place nor get definitive answers regarding the transponder chip.

For 2010 Legacy:

• The OEM key part number is 57497AJ00A. It is applicable to MY 2010 to 2014.
  
• The transponder chip is 4D6#? I have found both references to 4D60 and 4D62.
  
• The keyless entry frequency is 433 MHz. The FCC ID is CWTWBU766. Inside the key, there is an additional model ID which is CWTWB1U766.
  

For 2011-2014 Legacy:

• The OEM key part number is 57497AJ10A. It is applicable to MY 2011 to 2014. It is not applicable for any 2010 model.
  
• The transponder chip is 4D60 (please correct me if I'm wrong. I'm basing this on any reference I have found never pairs this key with a 4D62 chip)
  
• The keyless entry frequency is 315 MHz. The FCC ID is CWTWBU811. )I'm assuming that the module inside would have a model ID of CWTWB1U811.)
  

The main reason for this thread is to see if we can definitevely say that if you have a 57497AJ00A or 57497AJ10A key, that you need to find THIS transponder and THIS keyless entry module.

Can anybody concretely confirm the transponder chip inside the 57497AJ00A key? I opened mine up and there are two numbers, but I can't crossreference them: 9519 and R-05463.

Any insight into this would be greatly appreciated because many sites list 2010-2014 as being the applicable MY which just doesn't seem correct due to 2010 having the 57497AJ00A and the 57497AJ10A is NOT applicable for 2010.

ILCO has a blank, DAT17T13, that is for 09-10 Legacy and includes a 4D62 transponder.

Does anybody know if these keys can be cloned? Or can they only be added by registration?

From what I understand they can only be registered. Cloning would require a different type of key that would only work with a specific cloning machine.

I was able to re-register key for 08 STI using a "sbb pro2 48.88 48.99 SBB V48.88 Key Programmer Automotive Scanner Multi-Language SBB ECU Programmer Tool Replace SBB 46.02 33.LL" I got off AliExpress for around $70. They say they support cars up to 2017.

Just checking, so you went with the latest version (48.99) or one of the older ones?

After months of delays getting something from eBay, I got the flip keys. I went with 433 MHz and the 4D60 transponder. Unfortunately, when the tech (not dealer) was going to program the keys, when he selected the vehicle, it came up with a warning that said something to the effect "absolutely make sure you are not on a G blade key." He never saw that warning before and he doesn't do many subarus, so he backed out. I forgot the name of the unit he was using, but it was fairly chunky unit in black.

Does anybody know what a G Blade Key is and is that warning applicable?

Failing all this, I have an appointment next Tuesday at the dealership to get the programming done there.
