How to: Mazda CX-5 all keys lost

2015 Mazda Cx-5 Touring Sport 2.5l AWD
Just got my F100 from AliExpress 115$ 2 weeks shipping. Worked flawlessly. The all key lost function did not work, probably because i had one working key. I believe I chose start ignition and then it asked to erase all keys, and followed the prompts after 2 min-literally, I had two working keys. I had the red key symbol flashing at first, possibly bc i had two working keys in the vehicle. I think ill be able to cut the ebay key on my reg key cutting machine at work, forget the 70$ at the dealership. Ill be able to tell right away if its going south cutting it. This is all on my 2015 cx-5 key fobs with lock, unlock, and panic.
