971LM 950CB Remote only for a Red/Orange Learn Button of Liftmaster/Chamberlain Garage Door Openers(1Pack)

Worked perfectly and programmed within 5 seconds. These are a good replacement for my old single button remotes. As the add. said, they are only for the motors with the red or orange learn button. I like the added feature of an LED (which my old ones never had) that lights up when the remote is pressed letting you know the battery is good.

Picked these up for a client with a Chamberlain (LiftMaster) opener with a mfr date of 1997. These look just like the original remote. Stand on ladder, press the red square button on the main unit - small orange LED with turn on. Press and hold button on new remote. Main light bulb of main unit will blink, and your remote is now working. Remote battery supposedly lasts 5 years. I assume it's a CR2032 battery inside like the original remote, which are less than a dollar each. CR2032 batteries are 20-30 cents/ea as I write this. The original 28-year-old remote finally died not due to dead battery but a broken piece of circuitry inside. These replacement remotes work perfectly. Easy to use - instructions with pictures included in paper inside box.

El producto me parece excelente lamentablemente no lo puedo usar porque no tome en cuenta la frecuencia que debe coincidir con el motor de mi puerta

A bit tricky to program so had our nephew do that for us (old folks). They worked when our old ones stopped working!

Me sirvió de maravilla, no falla en nada. Lo recomiendo al 100%.
