What is the reason for the continuous flashing of the car and lock symbol on the Corolla dashboard?

[DeclanMarie]

The continuous flashing of the car and lock symbol on the Corolla dashboard is due to the anti-theft system being active. When the car doors are locked, the vehicle automatically enters the anti-theft mode, and the key light will flash continuously. The engine's anti-theft system consists of an electronic chip embedded inside the car key. Each chip has a fixed ID, and the car can only start when the key chip's ID matches the engine's ID. If they do not match, the car will immediately cut off power automatically, preventing the engine from starting. When the car is left unlocked, the electronic anti-theft system is in sleep mode, and the warning light flashes once every 5 seconds. If the light does not illuminate, it indicates that the anti-theft system is not functioning and has failed to enter the working state. In this case, you need to check the display settings and locate the remote lock mode setting to enable the horn with light flashing when locking.
