Universal Duplicator 4 Pack Garage Door Remote, 433.92 Mhz for Gate, Electric Gate Remote Control Key Fob, Cloning Keychain

Copied the remote on the left easily, remote on the right it failed, it copied but won't work. I need to research more, it may be the receiving unit. This is the third set I have got, ordered from different sellers. First set I can't get to work, second and this set does work for me copying FAAC controller.

One out of four doesn’t work. The rest are fine.

While they arrived promptly, they have defied all attempts at programming. Stepping through the process they appear to accept the cloned code but then don’t work.

I bought these as their frequency was specifically stated as 433.92 MHz. I set them up as per the tiny piece of paper with the instructions on and ‘Hey Presto!’ They worked to open and close the garage door perfectly. However, the pause button didn’t copy across. I’m not too bothered by this though. My original remote was only working intermittently so I was relieved to find these that actually worked!

Having seen a mixed outcome from users I thought I would advise on my findings, which might explain why it might be that for some it works whereas others it doesn't I could not get the fob to clone at all from the 4 button black and silver type in the photo, but from the red and grey 2 button unit it did exactly as the instructions said. Press and hold A&B together until the LED flashes continuously Let go of button B, but keep holding button A Still holding button A, press B 3 times to erase the factory settings Let go of both Now when you press any button the LED will not light up Now place both literally touching each other Press and hold the button on the old remote you want to clone press and hold button A, B, C or D (whichever one you want to use) on the new unit. The LED will flash twice, then again twice and then continuously. Let both go That should do it. As I say it seems to depends on what unit you are trying to clone from UPDATE - mine stopped working after 4 months but I was able to reprogram it again, not sure why it stopped signalling even though the LED was flashing. maybe the code had gotten corrupted.
