A door lock cylinder is made of metal tube that holds a bolt that extends from the cylinder and secures the door. It also connects to a set of pins that are spring-loaded to keep the cylinder from turning. When a key is inserted into a lock, the notches on the key force each of the pins to a size that matches their location within the cylinder's housing. When all the pins are in their correct positions, they form an uniform line, also known as a shear line. This prevents the cylinder and the bolt from advancing, locking the door.

To reset the autolock, press the lock and unlock buttons on the key fob for approximately 60 minutes. This resets the sensor, allowing the doors, lids for fuel and liftgate to lock themselves automatically when the ignition switch is turned off. Look over the Settings section of the Mazda Connect Owner's Manual to change the automatic lock/unlock setting. The hazard warning light and horn will flash to verify that the auto locking function has been turned on.
