Just wondering if there is a matched chip in the tip of the key, as there is on most modern keys?


It fits into the barrel just fine and it appears to be the correct length but they seem to have trouble cutting the key because of that bloody big plastic handle on the end. I have been tempted to removed that plastic but I don’t know how far up into the plastic the metal goes. It boils down to the accuracy of cutting the valleys and ridges to engage the tumbler pins.
