What Causes a Mercedes-Benz to Not Auto-Lock?
1 Answers
For models equipped with "Keyless Entry" functionality, the vehicle senses the key's presence. If the onboard computer detects the key inside the car, it will not auto-lock. This feature might also have been accidentally disabled, which can be toggled on/off via the diagnostic computer at an authorized 4S dealership. Auto-Lock While Driving: Speed-sensing auto-lock is an electronic feature that automatically engages the door locks when the vehicle reaches a preset speed (determined by the system), preventing accidental door opening. The activation threshold is typically factory-set, usually between 10-20 km/h. Key Benefits of Auto-Lock: Anti-theft: Locks doors promptly after driving starts, preventing door-pull robberies during traffic jams or at red lights. Child safety: Prevents young passengers from opening doors while the vehicle is in motion.
