How do people make exact copies of keys?

They use a small machine with a grinding wheel at one end. The original is held in a clamp, and the blank is put into another one by the grinder. As the original key is moved along and the indents are pressed against a thin upright post so the blank follows its movement and is ground to an exact copy. Dec 19 04, 12:01 AM

Or there's the less legitimate method of taking an impression by means of some modelling clay concealed in your hand and later making a brass casting from that. Used to be used by criminal types before the high security keys and locks came in. Dec 19 04, 6:42 PM
