Make 2009 Mazda cx9 key, which key programmer

Hey folks! Having problems connecting to a 2009 Mazda cx9...i tried skp900, ck100, and tcode and all I get is error. Customer says he tried starting it like 100 times with a key with no chip.

Did he lock up the computer? Does anyone know how to get my machines to connect to the ecu??

Thanks.

Solution 1

Try unplugging the battery for at least 30 minutes that worked for me in the past.
When you plug it back put jumper cables with your car running too

Solution 2

Try skp900 key programmer under cx7 it worked for me
