We have purchased (2) new remotes to operate our 3-door system. these are 3-button remotes by liftmaster. the instructions we recieved with the remotes says to locate the smart/learn button. we have control boxes model# sel-201 but can't seem to find the smart/learn button on these control boxes. could you let me know where to locate the smart/learn button so we can program our (2) new remotes to control the 3 overhead doors. thanks

The Learn Button is in a Silver little metal box that is in the opener housing but separate from the opener itself, pry off the case which kinda wraps around the reciever, it will say liftmaster of chamberlain the learn button will be in the reciever

To change the code you need to locate the smart/learn button which is near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in any 4 digit code you like and press enter.

See if this works for your car.

1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxillary, and/or the car door must be shut).
   
2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.

You can also get remote units that connect to the same terminals that you would hard wire a button to. You really do want a later remote, as they all now use rolling code technology. Essentially you have to "invite" a remote and the unit and remote agree on a code. From that time on, the code changes every time that you use the remote (automatically, you do nothing). Way better security, and a guy cannot just run a frequency generator and open your door.

You do not have one. Just went through that myself! Tried differant universals none worked! Must buy the 109130-390
