Yamaha Key/Ignition question

[Djkringe]

Bought a new ignition for my G16 electric. Installed it just fine as the connection was prefab and fit just right. Works great and looks way better than whatever was on there before. Figuring my teens and wife would be driving the cart I decided to get some more keys. I ordered a pack of ten Yamaha golf cart keys off Amazon and when they came they were already precut and don't fit in my ignition. Looking at other listings they all seem to be cut the same way. Are all stock Yamaha keys the same? I figure I am going to run up to Ace and see if they can make me some copies of my current ones, but am kind of bummed I can't use any of these other keys.
