Re: knocking phil j
you cant program your own key on the 156. the ebay ads are referring to fiat code system1 vehicles (with a master key for programming), your car is system 2 or 3 (check for the number on the metal part of your key)
the glass phial chips work in exactly the same way as the chip in your original key, they are simply from different manufacturers. either way that is not a problem since you are fitting your old chip in the new key. that will work no problem but make sure you fix your chip in a good place, by that i mean where it can be read easily.
