Anybody know the brand and or a site where I can find that flat, adjustable tension wrench with C' shaped jaws that fit into the top and bottom of a key way?
It has a small brass acorn nut for adjustment of the opening of the jaws rather than spring tension.
The function is similar to the common 'Y" shaped wrench for auto locks with a spring shutter but you can use it in normal door cylinders.
Any ideas appreciated.
