I purchased my Challenger used almost a year ago. When I bought it, it did not have the keyless remote. The power locks on the interior of the car have never worked unless the car is powered on, once it's running everything works fine. I got the keyless remote today and had it programmed to my car...same issue. I can remotely turn the car on using the fob however; the lock/unlock features of the remote do not work unless the car is on. Has anyone else encountered this issue?
