How do you reset code p0513 on an 04 pt cruser?

To reset the P0513 code on a 2004 PT Cruiser, first ensure that the key is in the "Off" position. Then, disconnect the vehicle's battery for about 10-15 minutes to clear the code from the engine control module (ECM). Reconnect the battery, start the car, and check if the code reappears. If it does, inspect the key and ignition system, as this code often relates to an incorrect key or issues with the immobilizer.
