Accordingly, I selected digits that still work fine without sensitive problems. Using those digits to create the 4 digits code, guess what, it works like a champ without the expense of buying a new. Feel pretty good for myself on this one, at least for today, I think 🙂
Our garage door opening has problem recently. It accepts 4 digits code occasionally. I always can replace it with a new one. Or, push it many times with a “hit and miss” mentality. But, after careful thinking with many trials. I kind of figured out which digits lost their sensitive in its electric board inside.
