Iron rolling door remote that cannot be read

Sub-GHz
#1

I have an iron rolling door remote that cannot be read. It can be detected as 915MHz, but I don’t know about FM. Recording with AM has no waveform, so I tried recording 915MHz FM 238 and 476. Please help me how to make it readable by ZERO.

By the way, it use in Taiwan and has no FCC number.

No one here is responding to me. Whether to record signal errors. This time, I recorded 915MHz, AM270 and 650 signals, each according to the method 10 times.

I checked that the 915MHz_AM270_DOWN file size is larger than the others, and the content values ​​vary widely. Should be the wrong record. Add the re-recording file here.

FM236… very similar to rolling code

#6

I have no knowledge of this. Just know that it cannot be read. The currently recorded signal, after playback, the access control has no action.

#7

I found this part from 10C2 on the IC and it may be si4010-c2-gtr. The documentation seems to mention the 27~960MHz operating frequency range. Does this help with getting zero to read?
