You might have a broken spring. Check on the a the header above the door there should be a tube with a drum on each end and 2 springs (maybe one) towards the center. If one of the springs has a gap (1-2 inches) in it. If it does you will need to call a door company in your area. I recommend you replace both springs. If you need to get you cars out some times you can help the operator to lift the door by lifting the door while the operator is lifting the door. Be very careful not to get your fingers in a pinch point and be sure to lower the door the same way.

The button on wall which has a little green lite in the center, keeps blinking, but the garage door does open


Press and hold the lock button for 3 seconds to stop the light from blinking. That blinking is the indication that the lock function is on and your remotes will not work.
