the transponder chip is the one in the orange oval, like Adrian said: "the black chip", but i thought the red line made it unclear. Don't look at the red line, it doesn't matter.
I had a broken key, and being very cheap i didn't pay for the chip to be duplicated, in stead I took apart the cover under the stearing-wheel and using tape i fixed the chip to the ignition barrel.
mi key has no longer got a chip.
