I only have one key for my panda, 2004 petrol 4x4. I got a key cut which opens doors and switches on the dash display. My idea was to take the chip out of the original key and stick it near the ignition barrel, then be able to use either key. But it won't work for some reason, it still works as normal with the chip back in the old key. Question is does anyone know where the pick up point is on the barrel ?
