How They Work
Contrary to popular belief, the electric opener does not provide the actual lifting power to open heavy electric garage doors. Instead, most of the actual lifting power comes from the counterbalance springs attached to the door. These springs are under tension to lift the electric garage door via steel counterbalance cables. The electric garage doors opener provides only a small amount of force to control how far the door opens and closes. In most cases, the electric garage door opener also holds the door closed in place of a lock.
When the remote transmitter sends a code, it generates a new code using an encoder. The receiver in the garage, after receiving a correct code, uses the same encoder to generate a new code that it will accept in the future. Because there is a high probability that someone might accidentally push the open button while not in range and desynchronize the code, the receiver generates look-a-head codes ahead of time. Rolling code is the same method of security used on cars.
