It is not clear to me exactly what signals that you try to send, for example, the exact name on irdb.tk.

I am not going to debug your code (hard with #include AIRremote.h...). But let me point you to that IrScrutinizer 1.3 that can generate Arduino code directly from (for example) irdb.tk. Just import the codes (as raw or parametrized), and export them as "Arduino Raw". This generates an .ino file that can either be used directly, or modified.
