  • Patent number: 9041510
    Abstract: An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry.

  • Patent number: 8648693
    Abstract: A key slot capable of accommodating an auxiliary key, which is a vehicle key other than a master key. A key lock mechanism locks or unlocks movement of the auxiliary key in the key slot, thereby allowing the auxiliary key to be taken out of the key slot in accordance with a lending condition of the auxiliary key. An invalid key return prevention unit permits the auxiliary key to be returned to the key slot in accordance with a return condition of the auxiliary key. If the return condition is met, the invalid key return prevention unit causes the key lock mechanism to lock the auxiliary key in the key slot. If the return condition is not met, the invalid key return prevention unit does not allow the auxiliary key to be returned to the key slot.
