I just bought a remote entry key online and got it and tried programing it with the instructions provided. They do not work though, I contacted the remote seller and he said it was my truck if it isnt responding. My question is, how do I tell if I have the keyless option.

 

keyless entry module is under the dash on the drivers side.
