What does it mean when a Mazda key keeps flashing?

[DelKingston]

When a Mazda key keeps flashing, it indicates the security indicator light, meaning the anti-theft system is activated. The car anti-theft system is designed to prevent the theft of the vehicle itself or items inside, consisting of an electronically controlled remote or key, electronic control circuits, alarm devices, and actuators. Taking the Mazda 3 as an example: it is a compact sedan equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 107 and a maximum torque of 146 Nm. The car measures 4515mm in length, 1745mm in width, and 1465mm in height, with a wheelbase of 2640mm, and is paired with a 5-speed manual transmission.
