Abstract
A key structure with illumination function including a grip housing composed of a first and a second casing, a key plate enclosed in the grip housing and having a key head extending out of the grip housing, a cell disposed beside the key plate and a light emitting diode having two terminals extending to two electrodes of the cell. By depressing a depression button, the terminals of the light emitting diode are electrically connected with the cell to form a closed circuit so that the light emitting diode can emit a light beam to illuminate the circumference of the key hole. Accordingly, in a dim place, a user can easily use the key to unlock the lock.
