true, but it lets you butcher the top to make a mushroom style key that doesnt brake everytime you hit it with your leg getting on and off the tractor. besides i have access to a key cutter so its no biggie for me.
Amazon sells Ilco 10 pack for about $10 + shipping. For the CK10 series the Ilco 1695 works and they're stronger than original Kioti keys. My original started developing a crack and it was only a matter of time until breakage.
