need help fast
Here are couple possible work arounds:
-If you have a spare key that's less used, try that, but wait at least 10min after your last attempt to start so as the system resets.
-Take some steel wool and clean the surface of the resistor in your key; try again.
-Place the key in the ignition and turn it to the on position(one before start), leave it on for 10min, then flip it off and then try to start the car.
These systems are notorious for failing, and if none of these solutions work you will likely need to bypass the system. That takes some work though, so not going to help you tonight.
