It can be done easily I believe. I bump a lot of 6 pin schlages with 5 pin bump keys due to the forward ramp of the key. This is present on any key so it should work in this situation also.
For the best book out there on high security locks and their operation, take a look at amazon.com for High-Security Mechanical Locks An Encyclopedic Reference. Written by our very own site member Greyman! A true 5 Star read!!

But, if I'm understanding you Zeke, then pip should not be cutting a 7th cut then, right? He should just cut the 6 existing cuts on the key to lowest, and rely on the ramp of the tip of the key to hit the 7th pin, correct?

instead of making a 7th cut
just maybe take a little extra off the shoulder ?

Yes, it would be worth a shot. I guess I misunderstood the post. Speed reading on the forums isn't a good thing I guess :lol: .

Taking off material from the 7 pin key will be innaccurate, and might not work. Do like Zeke and pip said, that should work.
