I just had mine in for work today. Before I had the OEM hitch installed I could always turn on the interior lights without a problem. Once the OEM hitch and relays were installed the interior lights on the ARE would only come on when the trucks lights were on. I don't have the auto lock, but might upgrade as mine is already getting a little tight and hard to turn after 9 months. Plus its a pain when its raining to get the keys out to unlock it.
