Once the lock switch has been activated, you can only control the garage door via the wall control unit. You may have forgotten to de-activate it after coming home from an extended period away, which is why the garage door seems to be stuck whenever you attempt to use your remote. Check to see if this is the case and simply unlock your remotes by pressing the lock switch again.
Replacement spring procedure took me exactly 1 hours including preparation and clean-up for double aluminum garage door. Watch the DIY video on Youtube, save $$, be careful with winding the torsion springs. Rule of thumb: 7' height door garage= 7' x 4 (each 1/4 turn) + 1 = 29 turns (1/4 turn), 8' height door garage = 8' x 4 + 1 = 33 turns (1/4 turn), and so on.... https://m.youtube.com/watch?v=Z_eZc-kh40c&feature=youtube_gdata

A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.
