’04 Dodge Ram 2500 remote start

I've never seen a black sentry key, personally. There should be a red circular light over to the right hand end of the instrument cluster.... it illuminates when key is turned on, and goes away after crank..... maybe 3/16 in diameter, little bit smaller. Or, open up the column and look for the antenna/module at the key chamber to be really sure. Gus Wherever I go, that is where I end up......
