Not the logic board because I was able to program a smaller keychain version of the original remotes and it works.
When you say "opener" are you refering to the SRT or the visor remote?
Also the white wire (being the antenna) is/always fully extended.
While waiting for your answer I erased all codes and started from scratch.
I reprogrammed the keychain and that worked. Then I used the same order for one of the previously used remotes and it didn't work.
Tried it for the second and no joy either.
I can't believe that the other 2 "larger" remotes would go belly up at the same time... I don't believe in coincidence.
Any other thoughts?
Have any cheap aftermarket suggestions in mind that would work with the 139.53677SRT3?
WOW mind blower!
I know that only ONE remote came with the installed GDO. The key chain and ONE of the larger remotes were purchased and programmed by me within a week of GDO installation. I can't tell which large remote came with the GDO or was purchased by me. All I can tell you is they all worked until batteries died in large remotes. That's when the party ended.
Thank you for your time.
