The key fob for my remote start system isn't working. I replaced the battery in the remote and now it doesn't do anything. The LED light turns on but it doesn't unlock my doors or start my car. I cannot find my user manual anywhere. Can someone tell me how to reprogram it or send me a copy of the manual? The numbers on the back of my remote are RPN471T, FCC ID: EZSDEI471 if that helps. Thanks
