Hi Ahmed,

You can block your MIFARE Classic if you write key values and permission bits to the sector trailer (block 3) which content is lost. You should know the key values which you will change and calculate the permission bits carefully. If you are in doubt, use the default keys as long as possible and change the keys at the last step in your personalizing phase.
