Presented at DEF CON 29 by

KeeLoq Remote Keyless Entry systems make use of radio frequency transmissions to operate and have many known weaknesses. A 64-bit manufacturer key is used in transmissions to encrypt an incrementing transmission sequence number in order to provide replay protection. This presentation is a journey into bringing existing research together to make personal Keeloq projects practical, ultimately repurposing a commercial receiver as part of a home automation system integration project.
