For models with a keyless system, press the unlock button or the keyless entry button on the driver's side door handle to open the door and deactivate the vehicle alert status. Turn the key to the "ON" position to successfully authenticate the engine anti-theft system. After completing the unlocking process, if any door, trunk, or ignition switch is not opened within 30 seconds, the doors will automatically lock and the alert status will be reactivated.

When it comes to disabling the anti-theft system on the Changan CS55, as a veteran driver who has owned this car for many years, I can share my daily experience. Usually, when the anti-theft system is activated, the most common causes are signal interference with the key fob or doors not being fully closed. The solution is to first try pressing the unlock button on the key fob or manually inserting the key to open the door. If that doesn't work, sit in the driver's seat, insert the ignition key, and turn it to the ACC position to disable the anti-theft system. Once in a parking lot, my key fob ran out of battery, and replacing it with a new one solved the issue. Checking that all windows, doors, and the trunk are securely closed can also prevent false triggers. For long-term maintenance, I change the key fob battery annually and park the car away from high-power electrical devices to minimize issues. If you really can't figure it out, don't force it by disconnecting the battery to avoid needing to reset other settings like radio stations. It's recommended to check the owner's manual or contact a 4S dealership—it's both convenient and reliable.
At the repair shop, I often see the anti-theft issue resolution steps for the Changan CS55. The basic operation is simple—just use the original key to unlock the vehicle. However, if the system is locked, it might be due to a lost remote signal or a faulty receiver module. We first use a diagnostic tool to scan the OBD port and read the error codes. Professional methods include reprogramming the key code or resetting the anti-theft module. Customers randomly disconnecting the battery may damage electronic components—we’ve encountered cases where owners’ mistakes caused module burnout. The standard procedure is to ensure all doors are closed, then attempt to deactivate using the remote or ignition key. It’s recommended to avoid exposing the key to high temperatures or humid environments to prevent failure. After repairs, conduct a comprehensive test to ensure system stability.
