Found out that Flipper doesn’t detect 125kHz Paradox key fobs.

Paradox tags are low-frequency (125 kHz) tags. Paradox key fobs come in 2 shapes (C704 teardrop shape and C705 clamshell shape). For the clamshell shape fobs, they come in 4 colors (black, green, blue, and red).
The fobs may have PTDE16, PTAP14, PTAP17, PTFE19, PTOC16, PTJA19, etc. characters below the serial number.
We can copy Paradox fob by the serial number printed on the back of the fob. In this example, you just need to enter 005:55485 when placing an order.
I can provide any debug info or assist in adding them to known protocols as I have two fobs and several intercoms that accept them.
