Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
If you have one of the newer models the duration can be changed by holding in the lock button until the light blinks (about 10 seconds.) A single blink indicates that the timer is reset to 1½ minutes. Repeat the procedure and the light will blink twice, resetting the timer to 2½ minutes. Repeat again for a 3½ minute interval, etc. up to a maximum of four blinks and 4½ minutes.
If your opener has the motion sensor feature and a person enters the garage and walks in front of the door control the light will come on for 5 minutes and then shut off.
