Key replacement

Hey all, recently purchased a 2012 sky sedan! Love the vehicle so far.

It came with one jackknife key (fob/keyless + ignition key).

What are my options?

I have spoke with a couple dealerships, quotes of around 300$. I know I can buy the device online but since I'm limited to one key, I cannot reprogram it myself.

Anyone have any advice?

I have a 2011 Mazda 3 and only one key just like you. I went to partsource yesterday, they said they can make a copy with only one key. Quoted me at $100 for the non-fob key cut and programed.
