Surprisingly your garage door just being locked can be causing your problem.
My garage door trolley is stuck.
A door that is stuck halfway open is a security risk allowing access to the garage and the home if it.
If you detect a small bend you may be able to straighten it out yourself but anything more extensive will require professional intervention.
Even with regular maintenance garage doors can sometimes stick refusing to open or close.
The garage door opener motor will hum when attempting to open or close the door but is unable to travel due to being lodged against the bolt tab.
Weather damage and harsh impacts can also distort your garage door track.
Typically this is caused by a mis adjustment.
