Ive had the xEm chip for a few years now and love it. Used my work HID Prox card for lab and parking access. Recently broke my card and got a new HID prox card. Same style/gen HID prox card as old one.
Went to read new card and write new card to xEM chip but it just won’t write to xEM chip. I can read old code from chip and re-write old code to chip. I can read new card and write that code to new card.
Ive used an older cloner from china (how I originally did it) and Ive used my Flipper Zero to no avail. Not sure what I am doing wrong. Thank you in advance for any insight and help.
Did you clone the original with a blue clover or something similar? What are you trying to use now to clone to it? A lot of handheld cloning devices set passwords on the t5577 chip when they write to them.
it doesn’t let you use a password when writing but there is a T5577 password remover that goes through a list of known passwords (incl the blue cloner password) to strip them out.
when removed, they’d be able to write as per usual with the flipper
For some reason, RFID (125kHz) seems to vary a bit depending on Firmwares, you want one with “Clear T5577 Password”
Factory is limited, I don’t think it is on there, but,
It is on Momentum, and a couple of others including Roguemaster.
IF IT HAS A PADLOCK, GO TO DE-BUG
SETTINGS - SYSTEM - DEBUG
Then come back and follow the guide
Here we can insert the password if known (which we do for the “Blue Cloner”), OR, it is probably as fast if not faster to let it auto search, so just Select “save”
