Here are some possibilities and troubleshooting steps:
* Factory Alarm System (Passive): This system usually activates if the car is broken into or tampered with. It will typically disarm when you unlock the car with the correct key or key fob. If it's persistently going off, you might have a faulty sensor (door ajar, hood ajar, etc.) Check all doors, hood, and trunk for proper closure. A failing battery can also trigger false alarms.
* Factory Immobilizer System (Passive): This system prevents the car from starting unless the correct key (with the transponder chip) is used. If your key is damaged or the system malfunctions, it won't start. You'll need a new key programmed by a dealership or locksmith specializing in car keys. This isn't a "reset" but a replacement or reprogramming.
* Aftermarket Alarm Systems: If you have an aftermarket alarm system installed, it will have its own instructions. Locate the alarm's control module and user manual to find the disarm/reset procedure. This often involves a specific key fob sequence.
* Keyless Entry System Issues: Problems with the key fob battery or its programming can trigger the alarm or prevent the car from starting. Try replacing the fob's battery.
* Electrical Problems: A faulty battery, alternator, or other electrical component can sometimes interfere with the anti-theft system. Have the car's electrical system checked by a mechanic.
What to Do:
1. Check your owner's manual: This is the first and most important step. The manual should describe the anti-theft system in your specific Pontiac model and year.
2. Try the key: Make sure you're using the correct key. If you have more than one key, try them all.
3. Check the battery: A weak battery can cause all sorts of electrical problems, including anti-theft system malfunctions.
4. Inspect for damage: Check all doors, windows, hood, and trunk for any signs of tampering or damage that might have triggered the alarm.
5. Consult a professional: If you've tried all the above and still can't resolve the issue, take your Pontiac to a qualified mechanic or locksmith. They have specialized tools and knowledge to diagnose and fix anti-theft problems. A dealership is an option, but often the most expensive.
In short, there's no universal "reset" button. You need to identify the specific system and its problem before you can address it.
