Japan has a new mobile phone that can automatically open your car door and start the engine. Just point and click. It was developed jointly by Nissan Motor Co., Ltd., NTT DOCOMO, INC. and Sharp Corporation. It works with Nissan’s Intelligent Key system, which has been installed in 950,000 vehicles since 2002. That system would be activated by the new phone via the Japanese mobile network NTT DoCoMo Inc.

The three companies announced in a joint press release that they will demonstrate the new phone at the CEATEC Japan 2008 conference, which begins Sept. 30. They hope to have the phone available in early 2009.
