How do I remove the security from flashing to start my car?

You need to turn the key to the on position and leave it in the on position. Leave it in this position for 10 min. The security light will go out. then turn the key off and then try to start the car. If it doesn't start repeat the steps. It will sometimes take up to 3 tries before it will take. Usually they will take the first or second time.if the battery has a full charge on it.
