  1. Junior, your 2003 Nissan Altima has a chip in the key that corresponds to your vehicle computer. Your key and the chip in it must match the vehicle computer or your 2003 Nissan Altima will not start. This system is referred to a vehicle immobilizer. If you want to install a remote start system in your 2003 Nissan Altima you need a 2003 Nissan Altima Immobilizer Bypass Kit. Hope this helps. Good luck with your 2003 Nissan Altima immobilizer bypass.

  2. I had some one tell me Nissan altima 03 has a chip on the key. Because of this you need to install the chip on the car also. Is this true? Can you shed some light on it?
