Can you elaborate a little on what you’re trying to do with the T557? Are you trying to input a specific password?

Thanks for getting back to me.
For the fun of it when I received my Proxmark3 I read my son’s apartment fob and saved the file to get in the front door of his apartment, he still can get in the back door. In the mean time he lost his fob, of course.
I guess the bottom line is I want to program:

00020078
84645269
50524F58
00000000
003DC258
55655547
99665955
6A656A55
00000000
00000000
00000000
00000000
00000000
00000000
00000000
00000000

into a T5577 fob/card. It looks like per the Proxmark3 the chip in my son’s fob was a EM4467/EM4569.

Thanks again and any help will be greatly appreciated.
