How does operating remote garage door opener when door is locked affect garage door opener?

Answer 1

If you have a garage door that has a lock engaged and you try to use an opener to get the door to go up, the motor (opener) will still try to engage and move the door into the up position. The motor and the lock will be fighting against each other and could damage your door. It could also damage the lock. If you have an opener on your garage it is always best to remove the lock. A garage door opener acts as a lock on it's own so it's unnecessary to have both.
