1. Identify the Cause:
* Accidental Trigger: Is the alarm going off for seemingly no reason? This is often due to a faulty door sensor, hood sensor, or trunk sensor. Check all doors, the hood, and the rear hatch to ensure they're properly closed. Sometimes a slight misalignment can trigger it.
* Key Fob Issues: Are you trying to unlock the van with a key fob that's malfunctioning or has a low battery? Try using the key to unlock the door.
* Intrusion Attempt: Was there an actual break-in attempt? If so, call the police first.
2. Turning Off the Alarm (Assuming Accidental Trigger):
* Key Fob: Try unlocking the van with your key fob. If it's malfunctioning, replacing the battery might solve the problem.
* Key in the Ignition: Insert the key into the ignition and turn it to the "ON" position (don't start the engine). This often disarms the alarm system. Leave it in the "ON" position for a few seconds, then try turning the key to the "OFF" position. Some models require leaving it in the "ON" position for longer.
* Using the Key: If the key fob doesn't work, use the key to unlock the driver's side door. This should disarm the alarm in most cases.
3. If the Alarm Persists:
* Check the Battery: A weak battery can sometimes cause strange electrical issues, including alarm malfunctions.
* Check for Faulty Sensors: Inspect the door, hood, and trunk latch mechanisms. Look for any damage, misalignment, or debris that could be interfering with their operation.
* Professional Help: If you've tried all of the above and the alarm continues to sound, take your van to a mechanic or a qualified automotive locksmith. They can diagnose the problem and repair or replace any faulty components.
Important Note: While many Chrysler alarm systems will disarm through the ignition or key, some might have slightly different procedures. If the above steps don't work, consulting your owner's manual is crucial. If you no longer have the manual, you can often find a digital copy online through a Chrysler website or a dedicated owner's manual site.
