A door lock cylinder is composed of a steel tube that holds a bolt. The bolt extends from the cylinder and locks the door. It also engages spring-loaded pins in order to stop the cylinder from turning. When the key is put into a lock, the notches of the key push each of the pins to a height that matches their positions within the housing of the cylinder. When all the pins are in the correct locations, they form an straight line, which is known as shear line, which stops the cylinder from rotating and also stops the bolt from moving which locks the door.

To reset the autolock, press the lock and unlock buttons on the key fob simultaneously for about 60 seconds. This resets the sensor and permits the doors, fuel-fill lid, and liftgate to lock themselves automatically when the ignition switch has been turned off. The settings for the automatic lock/unlock feature can be altered by referring to the Settings section of the Mazda Connect Owner's Manual. The warning lights and horns blink to confirm that the automatic lock function has been turned on.
