* Unlocking the car with the key fob: This is the primary way to disarm the alarm.
* Entering the correct key code into the keypad (if equipped): Some models had a keypad on the driver's door. This would be used to disable the alarm if the key fob was lost or malfunctioning.
If the alarm is going off due to a malfunction, you might need to disconnect the battery's negative terminal for a short time to reset the system. This should be a last resort, and you'll need to reprogram your radio after reconnecting the battery. If the problem persists, you should take the vehicle to a qualified mechanic or Chrysler dealership.
