2 x Replacement Garage Door Remote Control for Chamberlain Liftmaster Motorlift 94335E | 84335E | ML700 | ML500 | ML850 | Merlin + C945 | C840 Security + 433.92Mhz Handheld Transmitter

Very easy instructions, worked a dream immediately with Chamberlain Liftmaster door. The opener imediately learned this and its twin remote codes.Unlike a different product that just wouldn't learn the code from our existing remote.

I bought these for our liftmaster gate opener. You simply press the learn button the the liftmaster control system, and then press your chosen button the key fob. That's it - they just work.

As other reviewers have said, the installation instructions are really, really small (look like they have been written by an ant!). There was however a slightly larger instruction sheet in one. Hard to stand on ladder in garage with magnifying glass and remote in hand but once you get the idea of how to pair the garage door with the remote it is fine. One gave up working after about a month but so far the other is ok.

Great remotes, exactly like the the liftmaster ones they replaced, and a lot less expensive!

Stopped working in less than a year

You'll need a magnifying glass to read the instructions, but once you manage to read the instructions the remotes are easy to connect. Not sure about the quality, but working well for now.

Connected straight away, so far worked every time I opened or closed the door. Changing battery could be awkward as the back is held on with four tiny screws. (My original one snapped shut)

I have bought three of these now. They are very easy to set up and use and very reasonably priced.
