ABSTRACT:
An apparatus for programming a magnetic card key associated with a magnetic locking device. The apparatus is comprised of a computer coupled to an encoder unit. A list of codes are stored on the computer system. When a user desires to encode a magnetic card key, the identification corresponding to that particular key is input to the computer. Thereupon, the computer searches for the matching code. The magnetic card key is inserted into the encoder unit. A bank of electromagnets mounted in close proximity to the inserted magnetic card key is programmed by the computer to encode the key with the proper code.
