Dodge Avenger anti-theft system frequently activates, preventing the car from starting on Dodge Avenger

Some Dodge Avenger owners report experiencing issues with the anti-theft system frequently activating, which can prevent the car from starting. This problem may arise if the system detects an issue with the key used to start the engine. In some cases, owners have found that resetting the anti-theft system by disconnecting the negative battery cable for 30 minutes can help. Additionally, a low battery in the key or remote control may trigger the immobilizer, leading to starting problems. If the vehicle still won't start after a reset, it is crucial to check for other potential issues, such as a blown fuse affecting the system. The anti-theft system is controlled by the Body Control Module (BCM), which relies on signals from various switches throughout the vehicle. For those looking to set the anti-theft system in armed mode, it is necessary to remove the ignition key, close all doors, trunk, and hood, and lock the doors using the key or remote. Should the anti-theft system continue to hinder starting, consulting with an expert or dealership is recommended for further diagnosis and resolution.
