Replacement Locks for Storage Doors w/ CH751 Keys October 06, 2010, 01:12:58 pm Yahoo Message Number: 5570I 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:Industrial Lock and Hardwarehttp://www.iss4locks.com/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!
