发明名称 AUTOMATIC RESYNCHRONIZATION FOR REMOTE KEYLESS ENTRY SYSTEMS
摘要 <p>The present invention teaches a method and system for resynchronizing a remote keyless entry receiver having received a new encrypted message transmitted by the transmitter which does not match a previous encrypted message, also transmitted by the transmitter, and stored in memory. The method comprises a first step of transmitting and receiving a first new follow up encrypted message. Subsequently, the received new encrypted message is re-encrypted, and that result is tested against the received first new follow up encrypted message to determine whether there is a match. In the event both match, a second new follow up encrypted message is transmitted and received. At this point, the received re-encrypted new encrypted message is re-encrypted a second time, and that result is tested against the received second new follow up encrypted message to determine whether there is a further match. If a match is made, the received second new follow up encrypted message is decrypted and the command within the received and decrypted second new follow up encrypted message is initiated.</p>
