菲亚特晶片钥匙匹配方法

菲亚特晶片钥匙匹配方法

菲亚特的Immo2的防盗性能卓绝，本人认为它的防盗比大众奥迪的第三代防盗更具安全性。该车的防盗系统是在集成了防盗、中控、雨刮等等功能的BSI电脑里，更换BSI或匹配钥匙（更换发动机电脑不用匹配）必须让钥匙芯片跟BSI做匹配才能使用。

BSI里从93lc66存储器里读出的数据

数据中绿色表示已配有4条钥匙，红色为4条钥匙的数据，蓝色为防盗密码。

第三条钥匙晶片数据file:///C:\Users\ADMINI~1\AppData\Local\Temp\ksohtml\wpsAA3B.tmp.png

第四条钥匙晶片数据file:///C:\Users\ADMINI~1\AppData\Local\Temp\ksohtml\wpsAA3C.tmp.png

找到第三、四条钥匙在数据中的位置对照一下两条钥匙晶片里的数据，你会轻易地知道晶片数据是怎样写进BSI数据里的。如果是如丰田等车做到这一步已经可以着车了，但菲亚特不行，真正的壁垒还是在钥匙晶片里面，我们则需要用专用仪将防盗密码相关的加密数据写到晶片里才能匹配成功。
