Upgrade kit for an ignition key and methods
One variation of an upgrade kit—for an ignition key corresponding to a vehicle and including an immobilizer transponder and a keyless entry transmitter—includes: a wireless jammer configured to interfere with wireless transmission from the immobilizer transponder; a wireless receiver configured to receive an unlock request from an external device; a relay configured to actuate the keyless entry transmitter to unlock a door of the vehicle in response to the unlock request; and an enclosure configured to contain the wireless receiver and a portion of the ignition key.
1. An upgrade kit for an ignition key corresponding to a vehicle and including an immobilizer transponder, the upgrade kit comprising:
a wireless jammer configured to intermittently interfere with wireless transmissions from the immobilizer transponder;
a wireless receiver configured to receive vehicle command or request an external device; and
an enclosure cooperating with a portion of the ignition key to contain the wireless jammer, the immobilizer transponder and the wireless receiver, said enclosure further containing a motion sensor, wherein the wireless jammer is actuated in response to detected motion of the enclosure by the motion sensor;
wherein the improved ignition key functions as an access device to a corresponding vehicle for use in a shared vehicle service.
2. The kit of claim 1 , said enclosure further containing a keyless entry transmitter.
3. The kit of claim 1 , said enclosure further containing a battery.
4. The kit of claim 1 , said enclosure comprising a feature to engage a key dock.
5. The kit of claim 4 , said enclosure containing a sensor configured to detect proximity of the key dock.
6. The kit of claim 1 , said enclosure further containing an orientation sensor.
7. An upgrade kit for an ignition key corresponding to a vehicle and including an immobilizer transponder, the upgrade kit comprising:
a wireless jammer configured to intermittently interfere with wireless transmissions from the immobilizer transponder;
a wireless receiver configured to receive vehicle command or request an external device; and
an enclosure cooperating with a portion of the ignition key to contain the wireless jammer, the immobilizer transponder and the wireless receiver, said enclosure comprising a feature to engage a key dock and a sensor configured to detect proximity of the key dock;
wherein the wireless jammer is actuated in response to removal of the enclosure from the key dock;
further wherein the improved ignition key functions as an access device to a corresponding vehicle for use in a shared vehicle service.
8. The kit of claim 7 , said enclosure further containing a keyless entry transmitter.
9. The kit of claim 7 , said enclosure further containing a battery.
10. An upgrade kit for an ignition key corresponding to a vehicle and including an immobilizer transponder, the upgrade kit comprising:
a wireless jammer configured to intermittently interfere with wireless transmissions from the immobilizer transponder;
a wireless receiver configured to receive vehicle command or request an external device; and
an enclosure cooperating with a portion of the ignition key to contain the wireless jammer, the immobilizer transponder and the wireless receiver, said enclosure comprising a feature to engage a key dock and a visual indicator configured to display a visual signal in response to removal of the enclosure from the key dock;
further wherein the improved ignition key functions as an access device to a corresponding vehicle for use in a shared vehicle service.
11. The kit of claim 10 , said enclosure further containing a motion sensor.
12. The kit of claim 11 , wherein the wireless jammer is actuated in response to detected motion of the enclosure by the motion sensor.
13. The kit of claim 10 , said enclosure further containing a keyless entry transmitter.
