A key-configured transmitter design has a housing for containing the electronics thereof and a key blank which may optionally be cut to conform to the key shape of the vehicle ignition key or any other key the user might otherwise use on a regular basis. In this manner, it is possible to substitute the transmitter of the present invention for a key that the user would otherwise retain in his pocket or purse, thereby obviating the relative inconvenience of prior art transmitters, which require the addition of a transmitter device to their pocket or purse. The key blank serves the dual purpose of a real key such as for operating the vehicle's ignition and also as an antenna for radiating the oscillator signal produced by the transmitter of the invention. |
