It’s time you remove the cover your garage door and put all the bolts and screws in the same place as ziplock baggie. My advice when you open the garage door opener is to record the location of screws and bolts so you will not lose track of when it will be putting it back together.
Note the location of the part that you open with a number.
Note of each section that you have let it go and give a number, when you will put it back you do not need to bother to remember it again.
