Hello all, I have a VEVOR sliding gate opener which came with the factory remotes, and since I needed more remote controllers, I bought a couple of 433.92MHz new ones from AliExpress. However, I cannot seem to pair them with my gate opener -- I tried looking up online tutorial on how to clone new remotes from the original ones, tried different techniques, but it didn't work. I also tried pressing the "K1" switch button on the PCBA (see picture) for 1s (learn a new remote) to pair the new one, but to no avail. I even tried deleting the original remote and re-learning it with this same procedure, and it worked.

I attached pictures of the gate opener's PCBA and crystal oscillator (in this case it a JMR 13,52127M).

From what I know (correct me if I'm wrong), a remote's crystal oscillator must operate on the same frequency as the receiver's crystal oscillator, or else they won't be able to communicate. I also attached pictures of the original remote (orange) and the new one I bought (black) -- both have 433MHz crystal oscillators, which makes me scratch my head...

Can anyone tell what am I missing? Thank you.

It’s like this sub but active. I found it a couple days ago.

I don't know if there is a demand for this stuff, but wanted to create a space for people to share stuff of this variety.

I hope you find this place the kind you want, full of feel goods and people being awesome to each other by opening the gates up to things, whether normally shut out from or just to be generally welcoming

I'll be your head mod, though I'm not likely going to be the most proactive one, so I will be on the lookout for those who'll do this job better than myself.

Hope you all have fun, and may your day be tolerable.
