Abstract
A method for programming a lock to accept a key. The device will erase all the codes currently stored in the memory and program a new key value. The process requires several steps of turning the key to one of two positions when an LED is illuminated to indicate that the key must be rotated. After successful responses, all the codes currently stored are cleared and the security code of the new key is stored.
