Hey Folks, On my '98 Santa Fe, the door lock (silver, rectangle that you unlock then twist) is really tricky to operate. When I insert the key, the rectangular lock ejects and then I'm required to twist it to operate the levers that protrude out either side of the door, thus locking into the trailer walls. The levers move quite freely when the door is not engaged but they can be a BEAR when the door is in locked position. Every once in a while, they will lock or unlocked smoothly, but usually its a fight. The side levers don't appear to be misaligned in the camper walls to created friction or blockage, so I'm at a loss. Anyone have this issue before? Any tips/tricks to make this work? I don't want to damage the lock by forcing it, so I'm seeking advice. Thanks in advance!
