I think I posted it on here before, but if you are looking to replace your CH751 lock cylinders and keys, here's a really great source:

I just replaced all of my locks with new cylinders that use the much more secure tubular keys.
I ordered everything from them: cylinders, keys, finger pulls and cams. All the cylinders are keyed the same, took about 2 hours to replace all the locks. Turned out great.
Approximate cost was $12/lock. Everything included.
Just wanted to pass on info on a good vendor!
