Functions of the Automotive Central Locking Control System

The vehicle's central locking control system features key-linked locking and unlocking functions, as well as a key entrapment prevention function, detailed as follows:

Two-Stage Unlocking Function: Within the key-linked unlocking mode, a single-stage unlocking operation allows only the specific door into which the key is inserted to be opened via mechanical means; a two-stage unlocking operation is required to simultaneously unlock all other vehicle doors.

Key Entrapment Prevention Function: This feature prevents the doors from being locked while the ignition key is still inserted in the ignition switch, thereby avoiding situations where the key is inadvertently locked inside the vehicle.

Safety Function: If the ignition key is removed while the doors are already locked-regardless of whether the doors were locked using the key or via keyless means-the doors cannot be unlocked using the interior door lock control switches.

Generally, all vehicle doors can be simultaneously locked and unlocked by operating the key in the lock cylinder of either the front right or front left door. Furthermore, if a door-locking command has been executed, yet a front door remains open and the ignition key is still inserted in the ignition switch, all vehicle doors will automatically unlock to prevent the ignition key from being left behind inside the vehicle.
