so i just bought a set of 5 keys off ebay. i am going to the hardware store by my house to make a couple copies of each one (those guys probably think i'm crazy by now). then i'm gonna try and modify the tip/shoulders with my dremel tool. so here's my question;

some of the keys look different than others. in that some have peaks that are maybe 3 mm high while others have much higher peaks. does this matter? also THE BIG THING THAT CONCERNS ME is that the tips on some of the keys have this huge tooth on them. meaning that the peak on the tip is at maximum height while the other peaks are the smaller type. i will try to put up a pick of this soon.

do i need to fix this giant peak at the tip or is it supposed to be like that?

does anyone know anything about this. i am totally lost. thanks so much

By your explanation it *sounds* like your keys should be OK. The heights of the peaks will sometimes be different.

A common misconception is that the pins rest on the peaks, when in fact they rest in the valleys (cuts). The slopes are the surfaces that interact with the pins and transmit the bumping force to them. If you have a homemade key, and you have tried bumping a few times with it, you should be able to see marks on the slopes where the bevelled edge of the pin is hitting. If one of the slopes has a bigger dent in it then an uneven amount of force is being applied to the pins (meaning the cuts are not all the same depth).
