摘　　要：基于用户和生产厂商对汽车安全性能要求的提高,被动式无钥门禁(PKE)系统采用了保密性很高的KEELOQ滚动码技术,具有很强的防盗功能。另外。由于PKE系统可以自动执行对用户的身份识别、自动开锁车门,配备PKE系统的汽车给用户带来极大的便利。本文对PKE系统的工作原理及其关键技术做了详细介绍。As consumers and carmakers have increased the demand of the safety performance of automobiles, the Passwe Keyless Entry （PKE） system adopts the Keeloq technology, which has high security. So the PKE system has strong capability of guard against theft. Moreover, the PKE system is very convenient for users because it can recognize the users＇ ID and open or close the car door automatically. The paper introduces the operating principles and key technologies of the PKE system in detail.
