My LiftMaster or Chamberlain remote control has 8 or 9 switches. How do I code it?
If your LiftMaster or Chamberlain remote control has more than nine code switches, you will have to call LiftMaster’s S.O.S HotLine® at 1-800-528-5880 and speak with a technical service representative. If your remote control has eight or nine switches, the replacement transmitter will be a model 61LMC. This remote will work with all LiftMaster/Chamberlain openers that were manufactured between 1984 and 1996. It will not work with the new Security+® Rolling Code Garage Door Openers. If you have a current remote with 9 switches, simply match the switch settings in the new remote to the switch settings in the old remote. The new remote control should automatically work. If your old remote control or receiver has only eight switches and they are numbered 1-8, match switches 1-8 in the new remote to switches 1-8 in the receiver and/or old remote control. Set switch number 9 in the new remote control to the middle, zero position. If your old remote control or receiver has only eight switches
