The 878Max wireless keypad uses a orange learn button to program the keypad's code. The 878Max will open or close your garage door without using a remote control or key. The 878Max wireless keypad can open the door using a private 4-digit code you program directly into the unit. You can also program it with temporary access codes for visitors or delivery and service personnel so they can gain access to your garage without having to give them your personal code. This 878Max keypad includes mounting screws, battery and programming instructions.
When you match the model number 940CB on the back of your old keypad the new 878Max will be the right replacement keypad.
