I have a 1/2 hp Craftsman chain drive,billion code garage door opener 139.53648SRT2 made in 8/98. It came with two (3)button remotes and I had it programmed into the homelink system on my Chrysler vehicle and my boyfriends chrysler vehicle. Now we have seperated and I do not want him to have access to the garage. I have figured out how to erase all the codes so that the only way to open the door is from the hard wired wall button. But everytime I try to reprogram the remotes, it activates the homelink button in my car again which leads me to believe that his would work as well. I have been told that I should buy new remotes and that would solve the problem. So I went to Sears and the salesman told me I did not need to do that. He said to just unplug the unit for 10 minutes, then erase the codes and reprogram the remotes. I tried this and still it reactivates the homelink with the same code. I purchased a keyless entry pad thinking that it would offer a different code but he sold me the wrong one. The one he sold me is for a 315mhz and I think I need one for a 390mhz? I am frustrated and desperate for the correct information.Please help if you know how!!!!!
