Hello guys,
I got some HID prox II fobs off ebay recently and l cannot seem to write on them.
They are 26bit basic Prox II fobs, Look unused but, they are sequentially numbered.
When I write "lf hid clone ABACDEEA" , it seems it takes it, However, when I re-read , nothing changed.
If its indeed password protected, is there a way to reset the password and re-format these fobs anyhow?
Thanks for your valuable input.

t55x7
lf t55 detect -- if ok, try lf t55 info
EM, there is also the 4x50 to try
Iceman, thanks ,tried them all. they're all no use,unfortunately
Now my question is, Is it even possible to re-program these fobs at all on proxmark?, for example, to change its TAG ID numbers and Facility Code ect? Even if we had the password
HID Prox TAG ID: 2004da883a ( 09211) - Format Len:26bit - FC:109 - Card 09211
TIA

Those tags will be password protected. There is no crack. Brute Force might take 3 years or you might get lucky.
Also iirc they are t55x7 chips.
Likely the tag won't have the "correct" traceability values as hid often changed them. (Which is what is read to ID the chip.)
The other problem with those tags is the Chip's antenna is incredibly small and weak. (The reason hid discontinued that line). iirc about the only way to talk to them with the pm3 is to have the tip of the tag inside the pm3 antenna winding.
Obviously depends on your antenna
So even if the traceability values were "Correct" the tag likely didn't even "hear" the readblk cmd.

HI marsh, thanks for confirming,
