1. A method of duplicating a key, comprising:
- storing, by a key duplicating machine, key blanks of different cross-sectional profiles;
receiving a master key in the key duplicating machine;
automatically detecting, by the key duplicating machine, a cross-sectional profile of the master key;
automatically selecting, by the key duplicating machine, from among the different stored key blanks, a key blank whose cross-sectional profile matches the automatically-detected cross-sectional profile of the master key; and
automatically cutting, by the key duplicating machine, the selected key blank to duplicate a key tooth pattern of the master key.

Abstract
A method of duplicating a key includes receiving a master key in a key duplicating machine. The machine automatically detects a cross sectional profile of the master key. The machine automatically determines, based on the detected cross sectional profile, a type and model of the master key. The machine automatically selects a key blank that matches the type and model of the master key, and then automatically cuts the selected key blank to duplicate a key tooth pattern of the master key.

5. A method of duplicating a key, comprising:
-
receiving a master key in a key duplicating machine; automatically detecting, by the key duplicating machine, a cross-sectional profile of the master key by the key duplicating machine attempting to close a pair of sliding elements, having a profile of a particular type of key, around a blade of the master key, and determining that the master key is of the particular type based on the sliding elements successfully closing around the blade; automatically determining, by the key duplicating machine, a type of the master key based on the detected cross-sectional profile of the master key; automatically selecting, by the key duplicating machine, a key blank that matches the type of the master key; and automatically cutting, by the key duplicating machine, the selected key blank to duplicate a key tooth pattern of the master key.
