It is required to change the batteries in the remote if the lock button is functioning but the garage doors cannot open and close the way it is expected. This can be done by locating the small hole on the side of the remote in which the screw driver is inserted to scrape the cover. After this, take the old batteries and bring them to the nearest auto supply store. To facilitate you to pick out when you get home, embed the batteries, and then use the instruction manual. You can find the reprogram code on the box of the remote control. One of the two solutions can be useful when the garage door is not primitive, and had proper maintenance.
