Many are probably of aware how widely the CH751 lockset is used on Genset cabinets, RV's, lock boxes, bins on bucket trucks and other vehicles. In some situations it may be good to have a CH751 key and if you have a lockset using a CH751 key you may want to change it...Added..Because I have a key
Those that do use the 751 also have a murphy switch on them, well hidden. (Or should, if it's yours ---)
I had a car that was stolen three times, but it never got very far away. I had installed a cut off switch for the electric fuel pump under the driver's seat. It gets power two ways, one when cranking, and one while running ( key positions). By switching the run leg, it would start easily but die within a block. It was found about half a mile away last time, with no damage, and drove perfrctly , once the switch was thrown.
The CH751 lock is easily defeated using rudimentary tools. Not for secure storage. But as was said long ago "A lock only keeps out honest people"
