Does anybody know, what kind of frequencies or protocol the Simons Voss keyfobs use? I have tried detecting the frequency with an SDR but couldn’t find anything within the frequency range of the SDR dongle. Also nothing on NFC and 125kHZ. The type of fob can be seen here

Hi,
I can read mine with 125 kHz RFID (try to press the button a long time and move the flipper around), and copy some information (a hex code, “FC: 1” and a card number), but when I emulate the key, I can’t open the door.
Do you know if it’s doable to emulate that kind of keys ?
If it’s not using any kind of rolling or hopping codes it should be possible. Couldn’t read the code, no idea, why though.
Found some useful informations about this keyfob:
- https://fccid.io/UUC-02 → the active part (press button to send - therefore it needs a battery) works at 25 kHz → not supported by flipper. btw the range of this fob is very short (like rfid / nfc).
- you can buy the keyfob with ADDITIONAL passive RFID / NFC chip: SimonsVoss - Transponder 3064 with RFID chip - G2 - ModiTech (see “Options for RFID chip”) → depends on what you choose

would it be possible to take the antenna out of the keyfob and connect it to the flipper?
i mean when its using 25 khz then it has to have a antenna for 25 khz right?
Main things are circuitry and software (nobody knows how this device operates). Flipper has some LF RFID on board, but I doubt it will work efficiently at 25 kHz. Antenna is of the least importance, a piece of wire may suffice.
how could i connect the antenna with the flipper
btw thanks for the fast response 
It depends on what you will use it for, GPIO pins may or may not work. Reminding of the above, nobody knows how this device operates.
ok… but would it be possible to switch the antenna of flipper with the antenna of the keyfob?
(i think its still the same answer but yea… hope)
