how to disarm factory alarm?

I have a 2004 nissan wingroad. It comes with the intelligent key so i can lock and unlock the vehicle from the button on the outer door handles. I can also start without a key. I want to install a viper 5900 without the remote start. I would like to keep the factory keyless entry(intelligent key) and immobilizer. I would like to lock/unlock the doors with either the viper or the intelligent key . How do you get the viper to disarm the factory intelligent key and rearm it when i lock the doors ? Is there a wire from the factory alarm that i can use to pulse the arm and disarm with the viper. I'm not sure how to go about this installation. I dont want to have to disarm with the viper and then disarm with the intelligent key . I just need to disarm with either one and get the other to disarm automatically. Can someone tell me where the intelligent key control module is located or what it looks like . I'm been under the dash and every thing is in the factory harness. i have no idea where the intelligent module is located. If i know where i can figure out these questions my self. I do have a lot of questions. Thanks for whatever help i can get."I'm So Loud It Hertz"

I have just checked them but this is a non-USA market vehicle.It is not listed there. They sent me an e-mail address to inquire."I'm So Loud It Hertz"
