请大神看看CUID卡被电梯设备改写的问题

viewyou

复制了一张原卡，用的CUID卡，到电梯上读没反应，拿到PM3上发现卡被电梯设备修改，1-15扇区正常读，0扇区读不了，用知一密求全密获得0扇区密码是000000000000，但是读数据时又提示密码错误，用了默认密码FFFFFFFFFFFF,显然读出来的0扇区是错误的！其他扇区正常。大神们看看如何解决？我感觉是0扇区密码被电梯修改了，但是知一密求全密也无法读出正确密码，实在不知道咋办了！已经废掉两张CUID卡。

复制卡0扇区数据是不正确的，没有成功读取，感觉只是密码被修改，因为同时这卡还是门禁卡，门禁好使。

密码被改写也能读出来，最大的可能是0扇区的控制字段被改写了！

我也怀疑是控制字段改写了，否则不可能解不出密码，因为其他扇区数据、密码都没变，而且我用手机读卡，卡号还是正常的ID，说明就是密码和控制字段变化了。

打算换FUID卡试试，正在邮寄中……
