I just bought an OE Mazda key spare without the FOB for the CX-3.
I've programmed a third key in my 2013 Miata before, but the CX-3 has no key holes to put in for programming. How do I go about getting the PCM security to recognize the third chipped key blank I just bought?

That might be a dealer job but I'll see what I've got on my desktop computer later.
