I have a quick question. I put a remote start on my 2001 Chevy Tahoe a few months back. It has the factory keyless. I used the DEI 555L transponder unit to bypass the factory security but now the darn security light will not go out whether I start with the key or remote start. My friend had the same problem and took it to one of the local stereo shops and they tapped into a wire in the keyless module or something and now his light doesn't come on? Any idea what they did?
