No offense intended but the above answer isn't correct. If you hold the ';learn button'; on the back of your opener until the light flashes, that means you've cleared out the receiver's memory and your hand-held remotes (if you have any) will no longer work either. To program a keypad (assuming the ';clickmaster'; is compatible) you press and release the learn button on the back of your opener - do not hold it in. You should see a small light next to the learn button come on and stay lit. You now have about 30 seconds to get to the keypad, punch in your desired 4-digit code, and hold the 'enter' button on the keypad until you hear the opener click (or the light bulb will flash if you have a bulb installed). That's it. Now you just punch in the code to test it out. Hope this helps you!
