perhaps I failed to communicate correctly

if you have a fob that works, why couldn’t you remove the chip and install it close to the ring

take the existing circuit board and install it into a new fob case with key blade (no transponder because it resides on the ring)

If this works then you would be able to get a used FOB from EBay for the circuit board

install the circuit board from EBay used fob into eBay new fob with key blade

if the chip on the ring works then the rest of this would cost less than $50


i have progamed a used fob to unlock my car. I cannot dubilcate the transponder
