enable password for HID key fob

Hi,

I was wondering if there was a way to rewrite the block 0 to enable password lock so the key cant be re-written?

If its a T55xx tag you can change the pwd bit just like that by setting it.  Don't forget to change block 7 - which is the actual pwd.

Except if it is a genuine hid tag, it is already password protected, and it is unlikely to be a t55x7 chip.
