1. A laser-based key cutting machine for making duplicate keys, the key cutting machine comprising:
a master key imaging compartment having a scannable surface configured to receive and support a master key having a key blade for imaging;
an imaging device disposed proximate to the scannable surface and positioned to capture image data of the master key key blade;
a laser disposed proximate to the scannable surface and positioned to direct a laser line on the master key key blade;
a processor and a memory having stored therein instructions executable by the processor, wherein the processor is adapted to send and receive signals to the imaging device and laser;
a set of non-transitory instructions stored in the memory and configured, when executed by the processor, to:
target a laser and project at least one laser line on the master key key blade based at least in part on captured image data;
determine a set of measurements including distance and height measurements related to the master key and the projected laser lines;
based on the determined set of measurements, determine a pitch angle of the master key key blade relative to the scannable surface; and
target the laser and project a further laser line based at least in part on the set of measurements and the pitch angle; and
a key cutting component configured to receive a signal from the processor and cut a key blank based on a set of master key bitting information included in the signal.
