Hi!
At first my both remotes worked without problem until battery died in one of them. I have replaced battery in that remote and entered programming mode without problem but after clicking twice unlock button nothing happened. I tried dozen times without success and gave up finally. I had another one that was working so i didnt care. After battery in second remote died i have replaced it but now my both remotes cant be programmed. Ii can enter into.programming mode without problem but nothing happen after i click unlock buttons on remotes. What could be cause of this?
