Typically, you'll need to press the button on the remote key fob to activate this function, but certain systems allow you to activate it simply by walking near the car. Most systems work by emitting radio signals the key fob can detect.

Some systems are two-way meaning they also transmit status information to the driver on tiny screens inside the car, for example battery levels, window down/up status, and diagnostic information.

If the ECU is not able to receive this message, it remains locked and immobilized. This process is similar to how military planes use coded messages to identify themselves on radar.

Door Locks Door locks should meet building and fire regulations, as well as customer-specific or industry-specific security requirements. These may include accessibility for people with disabilities, security during an earthquake blast, blast resistance and retraction of deadbolt torque, and the durability of the lock. A door lock cylinder is made of metal tube that holds a bolt that extends from the cylinder and secures the door. It also works with spring-loaded pins to prevent the cylinder from rotating. When a lock key is inserted into the lock, the notch on the key will raise the pins to the height that is required for their placement within the cylinder housing. When all pins are in the correct locations, they form what is known as a shearline. This prevents the bolt and cylinder from rotating, thereby locking the door. To reset the autolock, press the lock button and unlock button on the key fob for approximately 60 minutes. This resets the sensor and allows the doors, fuel-fill lid, and liftgate to lock automatically once the ignition switch has been switched off. The settings for automatic lock and unlock can be changed by referring to the Settings section of the Mazda Connect Owner's Manual. The hazard warning lights as well as the horn will flash to verify that the auto locking function is activated.
