2011 Mazda 3 2.0L USA regular key

Can anyone will me through on the "All key Lost" here?
I used SKP-900 at first, all good, did it as 2013 year car, 2 keys, light out. Disconnect, never a crank. The Lock came back flashing fast after a few (10?) Sec in IGN on.
Used another programmer, same..
Used diagnostic scanner, when through dance with in and out codes, reset parameters in PCM, Programmed keys ,.... Same. Noticed that CEL flashing (ford flash codes) And then I lost communication to PCM. Left it like that for now, battery voltage - maybe... The shop will charge it.
Please, who can tell me exact steps? I am Not so familiar with this one.. I know it's simple but need to know if it's a car or me? I found a nest of some animal underhood. Related? possible..
Transponder type for can Mazda always 80 bit?

OEM chip or chinese? I did heard that the chinese one is a hit and miss.

Chip gotta be ID63 80 bit.

I took chips out from older Mazda keys. I'll check them with tango, yesterday checked with zedbull quickly.

Don't believe 80 bits are reuseable?
