New owner of a used 2004 Civic DX. The locks are all manual in this car. I finally figured out how to lock the driver side door by holding the handle while pushing the tab in. I have no problems unlocking the door from the inside. I haven't figured out how to use the key, though. It's almost as if the lock is locked. I put the key in and there is no give turning it either way. I cannot lock or unlock. I have tried turning the key with the handle pulled and still no good. Is there something I'm missing here, or am I going to have to take this in to the dealer?
