Frequently Asked Questions
Why is the Security / Anti-Theft Light on in my Chrysler PT Cruiser?
Your Chrysler PT Cruiser turned on the Security / Anti-Theft Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Security / Anti-Theft Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Chrysler PT Cruiser, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Security / Anti-Theft Light on a Chrysler PT Cruiser?
Cost varies widely because the Security / Anti-Theft Light can stem from several causes on a Chrysler PT Cruiser. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour.

Will the Security / Anti-Theft Light reset itself on a Chrysler PT Cruiser?
