MY MAIN KEY HAS A CRACK IN IT AND IS LOOKING VERY THIN 
HAS ONE BUTTON ON FOB,WHICH ONLY WORKED A LITTLE LIGHT.
HAS NO CENTRAL LOCKING! ON OPENING THERE IS A SMALL BATTERY,AND A LITTLE OBLONG "THING"
NEAR KEY,WHERE JOINED TO FOB.
IS THIS A CHIP?
MY SPARE HAS A VERY SMALL FOB ON AND IS HARD TO TURN,
BUT WOULD RATHER USE THAT THAN HAVE ORIGINAL SNAP OFF 
WOULD THE SMALL ONE HAVE A CHIP IN TOO 
WOULD I HAVE TO GO VW DEALER OR IS THERE A CHEAPER ALTERNATIVE.
COULD I PUT MY CHIP IN ANOTHER FOB,(SECOND HAND ONE)
HELP, ANYONE?
it tells mostly what you want to know
