Siri can make appointments, tell you the weather, but now she can start your car as well!

After we showed you how Siri could be hacked to use a custom proxy and execute custom commands, we knew it wouldn’t be long before additional hacks would start rolling in. [Brandon Fiquett] thought it would be great if Siri could remotely control his car, so he built this functionality into Siri using [Pete’s] proxy software.

The hack relies on the Viper remote start system he had installed in his car, along with a few modules loaded into his proxy server. His proxy server tweaks allow Siri to interpret a preset list of commands such as "Vehicle Start” and "Vehicle Arm/Disarm”, relaying the commands to the Viper SmartStart module.

We imagine that the back-end functionality is not unlike the existing SmartStart iOS app, but it looks like [Brandon] beat Viper to the game since Siri has not been made available to 3rd party developers as of yet.

Check out the video below to see Siri in action, then be sure to swing by his web site for additional videos as well as the code that makes this possible.
