Service theft system light

I have an 04 gtp and I put a remote start alarm smart start system in last week. I used a dei 555u for the bypass since I had one laying around and now I'm getting a service theft system light which I read is because it's seeing both keys. Does anyone know away around this or should I just order a new bypass that doesn't require the extra key?
 


I'm going to try to mess with it today. I'm thinking if I find a way to shut off the bypass using the key sense wire when I insert the key maybe this would fix it. I'll let u know.
 
Thank you! I have one on my '97 and I love it, got my system wired up so it turns on with the car, makes it real easy to find my car in parking lots, lol
 
I have the same problem with my 04 Grand Prix. I had a remote start installed, and noticed the Service Theft System message would appear when I activated RS, got in the car and left the key in too long without pressing the break. From this point, it would take 7 ignition cycles to clear. Now I'm using my spare key, and the light is always on, regardless of how I start the car. Will not clear.
