Advanced key programming

Hi.

I have a 2nd generation 2008 Mazda 6 and recently, because of badly closed door, the battery diyed.

After I've replace the battery, another problem came up.

The problem now is with the advanced keys. They simply don't open or close the doors, and the remote keys batteries are new.

Is it possible to reprogramme the remote keys for this model?

I've came up with several tutorials to do this but they are all for Mazda 6 1st generation model.

Thanks,

Luis
