A cylinder for locking doors consists of a tube made of metal that holds bolts. The bolt extends from the cylinder and locks the door. It also connects a number of spring-loaded pins that keep the cylinder from rotating. When a key is inserted in the lock, the notches on the key will raise the pins to the precise height required for their placement within the housing of the cylinder. When all pins are in the correct positions they form what's called a shearline, which prevents the bolt and cylinder from rotating and locking the door.

To reset the autolock system, hold the lock and unlock buttons on the key fob for around 60 seconds. This resets the sensor and allows the doors, the fuel-fill lid and liftgate to lock themselves automatically when the ignition switch is shut off. Check out the Settings section of the Mazda Connect Owner's Manual to alter the setting for automatic lock/unlock. The hazard warning light and horn will blink to confirm that the auto locking function has been activated.
