Abstract
After making measurements of a key, the measurements are converted into a compact format which can be read back at a later date or at a different location by apparatus capable of accurately reproducing the original key. The data may be stored on, for example, a sticker, paper strip, or magnetic swipe card. When the duplicate key is required, the data are read from the storage medium and transmitted to a suitable key duplication device to produce a reproduction key.
