Abstract
An electronic key device has a housing, a substrate unit, a battery holder, a key passage, and a key. A lock pin provided on the battery holder is biased toward the key by a spring. A distal end of the pin enter the key passage for retaining or locking the key. When the key is not being used, the key is covered by the pin. When the key is being used, the pin advances into a locking aperture of the key to lock the key. The pin locks the battery holder to the housing. The use of one pin for locking the key and the battery against the housing enables miniaturization of the device.
