It was a surprise to him that the car might have remote start added. But then again he also didn't know that truck had a bunch of other options like Bluetooth and XM (which still works even though I'm not paying for it

The zip-tie below it makes me think aftermarket but the mount looks like it's probably OEM. Any ideas? I live in Michigan and really want remote start for when Winter rolls around. When I bought the truck I was planning on eventually taking it somewhere to have remote start added but if it's there already and it's just a matter of reprogramming the remote I'll take it. I just can't find the programming button anywhere under the dash. Anyplace else I can look to verify if the truck even has remote start or if the dealer just put this fob on the keyring by mistake? I have checked to see if there were and foreign wires going to the battery and there is a line going to it but it's for an electromagnetic anti-rust system the previous owner added.
