Keeloq解码器可以通过Eeprom直接学习多个发射器吗

几乎所有的，是的。KeeLoq不需要任何特殊的硬件，所以内存是唯一的限制。然而，系统中多个有源接收机之间的同步计数器的管理是困难的。配对发生在接收机侧——接收机确定发射机何时有效。如果能够访问接收器EEPROM，则可以直接更改内存，就像配对过程已经完成一样。当然，存储在EEPROM上的数据对于安全性很重要，应该受到保护。没有标准或典型的方法来重写同步计数器。计数器对系统的安全性至关重要，典型的实现会竭尽全力保护它。然而，KeeLoq最终还是一个软件解决方案，作为设计人员，您可以修改任何您想要的东西。必须注意不降低系统的安全性。

Almost all, yes. KeeLoq does not require any special hardware so memory is the only limitation.


Technically, there is no restriction. However, management of the synchronization counter between multiple, active receivers in a system is difficult.


The pairing happens on the receiver side --- the receiver determines when a transmitter is valid. If you have access to the receiver EEPROM, it is possible to directly change memory as if the pairing process had been completed. Of course, data stored on the EEPROM is important for security and should be protected.


There is no standard or typical way to override the synchronization counter. The counter is critical to the security of the system and typical implementations go to lengths to protect it. However, KeeLoq is ultimately a software solution and as a designer you can modify anything you wish. Care must be taken to not reduce the security of the system.
