You have to remove the coil (bottom left of the circuit board) carefully without damaging anything else.
That in turn will remove the chip AND induction charging coil, so you will have to replace the rechargeable battery with a non rechargeable one.

It's not working because you cannot have 2 chips talking to the transponder ring at the same time.
