I don't think so, all the argentines seem to have put the chip in it, and games are so cheap that no-one really seems to rent.
My son didn't want to chip it either -he preferred to buy the super expensive games abroad...
I am told that all that can happen is that they block you when you play online, then you can re-chip it.
You can google where you can get it done, there are many places, but unfortunately I forgot how it is called in Spanish. Or maybe ask in a store where they sell the games?
