Garage Door Opening 4 Digits Code

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.

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 🙂
