I don't know specifically what your issue is, however I have a Liftmaster garage door opener (2 actually) with the "rolling codes" feature. I followed the directions in the manual and didn't have any problems. It helps to have a helper inside the car to push the button when it's time (you only have a short period of time to push the car opener after pushing the button on the opener).

I think it has an old code in it, will try to erase it and try again. Thank you.

mine doesn't appear to be sending signal.... I've erased, by holding outside buttons and seeing flash change. I then try to program the center button (as I've previously done on previous car) by pressing learn on opener.... but the opener doesn't see a signal. I have programmed another one, temporary unit, so it is not opener.

Has anyone had weak or missing signal from car? What can I check to fix it?

Try new battery in opener remote. Took me several tries.

Thanks but I'm programming the HOMELINK on the Charger... Anyone know how to troubleshoot this, if signal is weak missing?
