Simple, easy to program and incredibly easy to use, the Chamberlain 850CB multi-function one-button garage door opener remote is the perfect replacement or spare remote. This convenient, compact gadget can work on any garage door that operates on a 390 MHz frequency with a green "Learn" button. Even better, it can be used on automatic security gates that operate at that frequency; that makes this the perfect choice when you're replacing an old, broken or lost remote.

The Chamberlain 850CB is so versatile that it can even be used to control lights or small appliances in your home, all from the comfort of your car. Because it features cutting-edge technology that employs rolling codes – codes that change every time you use the device – it's ideal for top-level security that you won't find just anywhere.

Programming and using the Chamberlain 850CB multi-function one-button garage door remote is simple. Follow the detailed instructions that come with the unit as you press and hold the green "Learn" button on your garage door opener, press and hold the button on the unit within 30 seconds, and then do a quick test to ensure that it works. It really is that easy, which is why it makes a great spare remote, too. You don't have to worry about transferring one remote from car to car each time you switch rides if everyone has one that works.

This affordable and reliable Chamberlain 850CB is the right model for you if:
  • Your current garage door opener has a green "Learn" button on its motorhead
  • Your current garage door opener or gate uses a 390 MHz frequency
  • You need to replace an old, broken or lost remote

QUESTION: If u lost a remote can u buy a new remote and change the code just to be safe? by None N 3/20/2016
ANSWER: First of all, I would check with Chamberlain to see about changing codes. However, it seems to me that there are some dip switches on the back of the unit that could be changed and then re-synching your remote would provide the change you are looking for. However, again, I would get the model number of my opener and call Chamberlain to see if I'm right. by Jose N a
