Sniffing T5577 Reader to Obtain Codes (Without Access To an Original Fob)

Support
1

Folks,

Need your valued help.

A fob I cloned a while ago from having access to an original now doesn’t work at the reader, and I have no access to any new fobs that have been setup to clone another.

Are there any ways/options to sniff the T5577/AWID/Wiegand reader using PM3 or a Flipper Zero to obtain new codes? (Note: I own a PM3 so that route would be ideal)

If so, how can this be done? Any tutorials or commands you could recommend?

Many Thanks!

Sniffing refers to eavesdropping on the communication taking place between a reader and a tag…

Ok

So in the situation above, how could I obtain codes from the reader with no available fob?

Hmmmm, well tricky to answer.

It sounds like you shouldnt have access to this door.

Can you explain further why you can’t get a new fob or renewed access?

you can’t and you don’t.

if you have no fob to read or sniff you aren’t getting in.

More to the point, we talk about cloning transponders here because we support legitimate access use cases where people have the original fob and authorized access, but they want to migrate that functionality to their implant. Since you don’t have access to any authorized, I can only assume your intent to access whatever it is you mean to access is not actually authorized. We don’t support that.
