At one time, making duplicate keys required
hand grinding or filing a key blank. The method was difficult to master, and
only a locksmith could do the job accurately. Today’s technology makes creating
a duplicate key quick and cost-effective. Hardware stores are now equiped with
automatic or semiautomatic key-cutting machines, which are able to follow the
shape of the teeth along the key while grinding the blanks into precise copies.
1.Insert the original key in the vice with the teeth
facing upward.
2.Insert the blank key into the second vice, where the
cutting blade is located.

3.Close the protective cover and activate the machine.
The micrometer will trace the original key. It automatically controls the
angles and depth of the high-speed cobalt blade.
4.Once the duplication is complete, turn off the machine
and remove both keys. Use the high-speed wire brush to polish off any rough
edges or spurs.
5.Place the new key and the original against each other
and compare. They should be an identical match. If not, another key may need to
be cut.
