yellow antenna. The 877LM wireless keyless entry works with my opener. To program the keyboard, first create a four-digit passcode and write it down. Approach the wall switch, press the "Training" button twice. Then enter your four-digit passcode and press Enter. Your ceiling light should flash, done. Try entering the code on the keyboard, press Enter. Your door should open/close. Pros: Reasonable price, backlit, easy to program, easy to install, fast shipping. Cons: Only available in gray (I wanted white), may not last long (cheaply made) Hope this helps! Blessing. Some favorite verses: John 3:16 John 14:6 Jeremiah 29:11-13 Psalms 119.
