Abstract
A key assembly for mounting an electronic component in the head of the key. The electronic component is mounted in either an opening such as a bore or recess formed in the key head, or a carrier connected to the heel end of the key shank. In the former case, a closure member such as a plug or adhesively backed panel member is employed to close off the opening. In the latter case, the carrier is encapsulated within a plastic key head.
