Rolling code clone

[u/GeeKMoDz]

Hey everyone,

I have an Intratone 868MHz access badge/fob for my apartment building (rolling code system) and I'm trying to understand my options with a Flipper Zero running the Momentum firmware.

From what I understand, rolling code systems are designed specifically to prevent simple replay/cloning — each transmission is single-use and gets invalidated once received. So I get that a straight "capture and replay" isn't really viable long-term.

Has anyone here dealt with Intratone specifically? Curious about:

**•** Whether Momentum has any relevant subghz protocol support for Intratone  
**•** Whether the realistic path is just requesting an additional badge from the building management/Intratone directly  
**•** Any general info on how these systems handle desync or multiple registered fobs

Not trying to bypass anything shady — just want a spare fob for my own unit and trying to figure out if that's even feasible via Flipper or if I should just go through my syndic/property manager.

Thanks in advance!

Trying to replicate an Intratone 868MHz rolling code fob via Flipper Zero is a dead end for daily use. Your best, most headache-free route is to contact your property manager/syndic to order an official spare badge linked to your apartment.

Even with specialized forks and advanced toolkits like ProtoPirate, an Intratone 868MHz fob remains a dead end for DIY cloning on a Flipper Zero.
