Abstract

An improved key system incorporates a number of electrical components. In one main aspect, the key is provided with electrical communication to components on the vehicle when the key is inserted into the ignition. The key connects to an antenna associated with the vehicle, such that the combined antenna size is greater than would otherwise be possible. In this application, the antenna is utilized for garage door opener purposes, and a switch is mounted on the key for actuation of the garage door opener. In another aspect, the key is recharged when inserted into the ignition. Further, the key may be provided with various other functions such as memo, vehicle deactivation, two-way communication, and other security applications. In embodiments of the key, the switches are positioned relative to a thumb area such that inadvertent actuation of the switches is made less likely.

Claims

1. A key system for a vehicle, comprising:

a key including a first pair of traces embedded in a body of the key and a transmitter embedded in a head of the key; and

an antenna embedded into an interior component of the vehicle, the antenna including a pair of contact leads,

wherein the pair of contact leads of the antenna align with the first pair of traces of the key when the key is inserted into an ignition of the vehicle, thereby electrically connecting the transmitter with the antenna.

2. The key system according to claim 1, further including a rechargeable battery embedded into the head of the key and a vehicular battery electrically connected to the pair of contact leads of the antenna, wherein the rechargeable battery of the key is charged by the vehicular battery when the key is inserted into the ignition of the vehicle.

3. The key system according to claim 2, further including a control for controlling electrical power from the vehicle battery to the battery of the key.

4. The key system according to claim 1, further including a battery embedded into the head of the key and a recharging circuit for recharging the battery.

5. The key system according to claim 1, further including a switch embedded in the head of the key for opening a garage door.

6. The key system according to claim 1, wherein the key includes a second pair of traces embedded in the body of the key, thereby allowing the key to be inserted in any orientation into the ignition of the vehicle.

7. The key system according to claim 6, wherein one of the first pair of traces comprises a positive trace and the other one of the first pair of traces comprises a negative trace, and wherein one of the second pair of traces comprises a positive trace and the other one of the second pair of traces comprises a negative trace.

8. The key system according to claim 1, wherein the key further includes a mode switch and one or more other switches.

9. The key system according to claim 8, wherein the mode switch allows changing of a mode of operation of the one or more other switches.

10. The key system according to claim 1, wherein the interior component is a steering wheel.

11. The key system according to claim 1, wherein the interior component is an interior trim component.

12. A key system for a vehicle, comprising:

a key including a first pair of traces embedded in a body of the key and a transceiver, a control, a memory, and a rechargeable battery embedded in a head of the key; and

an antenna embedded into an interior trim component of the vehicle, the antenna including a pair of contact leads electrically connected to a battery of the vehicle,

wherein the pair of contact leads of the antenna align with the first pair of traces of the key when the key is inserted into an ignition of the vehicle, thereby enabling the battery of the vehicle to recharge the rechargeable battery of the key.

13. The key system according to claim 12, wherein the key further includes a switch for disabling the vehicle.

14. The key system according to claim 12, further including a microphone coupled to the control of the key for recording messages from an operator.

15. The key system according to claim 14, wherein the recorded messages are stored in the memory of the key.

16. The key system according to claim 12, wherein the key includes a second pair of traces embedded in the body of the key, thereby allowing the key to be inserted in any orientation into the ignition of the vehicle.

17. The key system according to claim 16, wherein one of the first pair of traces comprises a positive trace and the other one of the first pair of traces comprises a negative trace, and wherein one of the second pair of traces comprises a positive trace and the other one of the second pair of traces comprises a negative trace.
