Hello I purchased our Bighorn 3185RL back in April 2011 I have been having problems with our Southco Keyless Entry system. We replaced our system back in May the first system the keypad battery keep going dead after a week and the door lock was jamming. Since we replaced the system the keypad battery still going dead after one week. I have tried EverReady and Duracell battery's. I called Southco but they tell me to call Lippert and they want me to replace the system again and for me to pay for it up front and when I send the old system back they will refund me what do you think could be the problem with the keypad.
