How to wirelessly start your car using a text message.

Click show more...

Extend the range of my vehicle's auto-start using the cheapest solution I can think of. I would also like to keep vehicle modifications to a minimum (or none).

Trigger the auto-start remote using an Arduino connected to a cell service. User will send an SMS message to the device, which will validate the message then trigger a relay which will cause the remote to send a signal and the car will start. The device will be left in the car and run off the vehicle's battery.

Skills required
If you follow the tutorial, basic computer and electronics skills. I am assuming you can make connections using a bread board or soldering iron. I am also assuming your car already has a remote starter installed, and that you are willing to sacrifice one of the remotes.
