Typical Symptoms of Failure

Due to constant operation and external environmental factors, the rear door lock mechanism can wear out over time. The most common symptoms of failure include:

• The rear door does not latch, or closes only after repeated attempts.
• When activating the central locking system, the rear door remains unlocked or fails to release.
• Unpleasant metallic or grinding noises are heard during lock operation.
