I thought I had already posted this question once but I must be loosing my mind because its gone but anyway here goes; Last week my wife lost one of only two sets of keys to our 2002 Altima 2.5S. We looked everywhere with no success so I went ahead and picked up a new keyless enty remote. Its the exact same one that came with the car but I don't have a clue how to program it. I know you can program the remote for most Honda's without going to the dealership. Does anyone know what the procedure for programing the remote for an 02 Altima is if indeed there is a procedure for programing it myself? Any help would be greatly appreciated. Thanks.
