Chrysler PT Cruiser doors locking and unlocking while driving due to alarm system issue on Chrysler PT Cruiser

Some Chrysler PT Cruiser owners report experiencing issues with their doors locking and unlocking while driving, often attributed to alarm system malfunctions. These problems may arise when the alarm is triggered while unlocking the car with the key, causing it to sound unexpectedly. In some instances, the alarm system fails to operate properly, resulting in persistent alarms when they shouldn't be activated. Additionally, owners have encountered issues with the key fob, particularly battery-related problems that can usually be resolved by replacing the key fob battery. If the door locks do not respond to the key fob or automatic door lock buttons, this may indicate a malfunction in the remote keyless entry system or the vehicle's security system. Troubleshooting these issues often involves checking the RKE module for failures and ensuring that the wiring harness near the steering column and ignition switch is intact, especially if aftermarket modifications have been made. Addressing these concerns promptly is essential for restoring proper functionality.
