I am new here to this forum but was suggested it by someone on another page. Question you guys may or may not know. I have had my 16 SHO for about 1 year now. I had the keypad entry programmed and it has been working fine. The other day it stopped working for some weird reason. I have to master number but when I go to program it, it won't program. The master number doesn't work either. Any ideas?
