Nissan said that its intelligent key system, installed in more than 950,000 units of various Nissan models since 2002, employs two-way wireless communications technology to automatically unlock or lock the car door, and start or stop the engine.

Nissan and Sharp have integrated these electronic intelligent-key, wireless communications and electromagnetic technologies into the new handset. Nissan, DoCoMo, and Sharp will continue to develop the product with commercial distribution anticipated in early fiscal 2009.
