help! e65 73d all key lost..

[basica]

i, I don't know if this is the right place to be, but I need help. Somehow my car loses all the keys. The CAS module is manufactured and the key is not initialized. What I need to do to get it right happens a second time. They serve it for the first time, but I don't want to be told how. Now there is no way I can give that money to deal again.
