Any chance this is already being used nefariously? It would explain stories like this: http://www.today.com/news/police-admit-theyre-stumped-mystery-car-thefts-

  Of course it's already being used. When Average Joe thinks about a criminal he thinks some thug hood with a brick. The professional criminals are affiliated with syndicates and mafias have money and resources. They can hire the talent able to figure out decoding these trivial radio signals.

    > They can hire the talent able to figure out decoding these trivial radio signals. I don't expect even older radio access systems to be that simple to abuse. For example this application note from Atmel[0] describes such a system. It uses an AES-based MAC and a rolling window counter to prevent message spoofing and replay. I wouldn't bet this implementation is actually secure, but it's not so trivial to attack. Please note I'm not saying that criminals haven't abused vulnerabilities in these systems, just that it's not a simple matter of 'decoding these trivial radio signals'.
