There are two kinds of key codes: blind codes and bitting codes.ach number in the bitting code corresponds to a cut on the key blade. For example, a bitting code of 11111 with Depth and Spacing Number 46 specifies a Kwikset key with five shallow cuts.
For example, the virtual-key code for the LEFT ARROW key is VK_LEFT (0x25). For the complete list of virtual-key codes, see Virtual-Key Codes. No constants are defined for the virtual-key codes that match ASCII values. For example, the virtual-key code for the A key is 0x41, but there is no constant named VK_A.
