I want to change the code on my keypad for a Chamberlian Liftmaster Model 7220. Do you have directions for this.
Push he little red or green button on the back of the operner and then within 30 sec. press the four numbers and enter on your keyless entry. the light on the opener should blink twice. Have a nice day once you hit this new 4 number code your old one is gone.
Locate
the smart/learn button on the rear of the motor unit near where all
those white wires go. Press and immediately release this and then
walk over to the keypad and key in any 4 digit code you like and
press enter.
