The keyless entry on our Rushmore worked flawlessly for over 2 years. Didn't even need a battery. This Fall, it suddenly quit. So I figured it must finally need a battery. Tried several new batteries from different sources. No go. The keypad lights would light up, but no response. Lippert sent me a new keypad, even though it was way out of warranty. No go. Lippert sent me a new controller. Again no charge. The procedure to enroll keypads to the new controller didn't do anything. They sent me a new cable which I plugged in without installing in the door. Still nothing. I figured that we'd just have to start using the key from now on.
So I called Southco to see about getting a couple of extra keys. The customer service rep asked why I needed them, so I related the whole story. He volunteered to send me a keypad and controller and to do the enrollment and verify correct operation before sending them. AND he threw in a FOB. The parts arrived today. It's all working again.
All that to say that Lippert was responsive. But Southco went the extra mile to get this fixed. Good thing. I love that keyless entry.
