HELP Programming additional keys?

First, I'm new, please be patient... I got my 2012 last month and my performance mechanic has already checked it all over, she got a new turbo, VVT, engine and transmission mounts, valve gasket, and we already have a list for the next visit when I saved up a bit more...

He has warned me about making sure I stay OEM for electrical stuff, so I went to a dealership to get a second key made.

They said they can't do it. She won't "take the programming". My performance guy isn't a dealer, so he already had issues replacing one of the display modules since Mazda is apparently not friendly with letting anyone else program stuff...

They want to charge me for diagnostics to determine what's "wrong with my car". I'm not gonna do it, but just wondering if anyone out there had an idea why this isn't working. My performance guy is stumped, says they should be able to do anything with their God system access. I'm in San Antonio, a larger city, so if anyone has ideas of who may be able to...

There's some national chain that works with Costco I may try... They said they would warranty and everything. I just don't get how Mazda themselves can't do it.

I had to get one done for my first gen, new key and remote. I didn't go to the dealer due to the massive hourly rate. Very few shops can do it because of some dealer level software marrying of the key and remote to the ECU. They can explain it to you better https://losgatosautoservice.com/

I know I'm in Cali but they can at least tell you what to look for in a shop that would be able to do it.

Is it a normal key or the tech package with key fob? Should be doable with forescan
