A keyless entry system is provided for locked or disabled items. A transmitter carried by a person generates a signal with a predetermined frequency characteristic such that the generated signal is transmitted through the carrier's body. There is a receiver apparatus including a detector for detecting a signal with the predetermined frequency characteristic and a mechanism that is engageable by the carrier's body for providing signals transmitted through the body to the detector. When such signals are detected, a circuit is activated to unlock or enable the item. An alarm system may be provided which sounds under certain predetermined conditions and a latching mechanism may be utilized to disarm the alarm under certain conditions. |
