On 28-29 and early 30 you (do not) need a key to take it apart if you look at Tom`s picture there is a Botton head set screw on the side take it out and the tumbler will come out with the lock ring, sometimes they can be a little sticky so hold it in one hand and with the other hand pop it in and let popout it will knock the ring loose. on the 28-29 cable Bratton part #16370 30 with a oval speedo it used the same head but the cable is longer,
