ICT 433MHz Transmitter

Sub-GHz
#41

Yes …
First make sure that you are sending allways the same key and hopping, make sure that count is at 0000 and key doesn’t change when you press multiple times. If it opens the gate/door then the “problem” is NOT with the remote but with the reciever … in other words the system is using the fixed key only and works like a fixed code system, and doesn’t use the hopping/count… It’s just not using the capability of dynamic/rolling codes instead works as a normal simple / single code system.

I have one question, are you able to capture/READ your original remote with the correct frequency 434 and FM476 without preset / cuctum config with correct deviation ?

#43

Tried all the different combinations, but only 434 with 15kHz deviation will pick up signal.

I looked at a handful of readings, in every single one the Cnt is always 0000.
Additionally using this alt firmware, i am sure that the exact same key is being replayed.
Hence i suspect that as you have said, the receiver is not configured correctly for full rolling code support.

But since the remote Cnt is also not incrementing, I assume that also means the remote is designed incorrectly?

You just need to save a raw file with the correct frequency and modulation/deviation and you can send that with official firmware to get a functional remote/flipper as it looks like your system only cares for a valid Keeloq transmittion with the fixed code. You don’t need any other firmware, official/stock is just fine, you can’t save the codes with READ but you can simply save the signal with read raw and that is just what you need anyway. As long as you are transmitting on a frequency that you are allowed to transmit in your region you will be ok.
