i need help with the 555u immobilizer

i have an 2002 rsx i hooked every thing up the red wire to the power supply(white) and the blue to the remote start negative status output and put the ring over the ignition and got nothing there is a piece to the ignition that when you take it of the car doesn't read the key is this the factory transponder ring and do i have to try the alternate inter face if so what do i have to do to make the immobilizer work?

                                                               thanks alot

I also am assuming the unit uses a relay.  So... when you try to remote start, does the box 'click'?

Does the car start fine if you put a key in the ignition?

Is this an extra key?  Is it programmed into the car?

Unplug everything from the 555U.  Stick a working key in the ignition, but leave it in the Off position.  Attempt to remote start the car...does it work?  If it does, your remote start is hooked up correctly---your transponder interface isn't working---and that's where you'll have to start fixing things.

If it still doesn't remote start, even with a key sitting in the ignition, you have other troubles.

Next, insert the good key in the ignition, but this time move the key to Run.  Now, try to remote start....does it work this time?  If so, then you've probably missed one of your ignition wires--go back and check that.
