What is the reason for the continuous flashing of the Toyota RAV4's locking light?

If the car's engine immobilizer light flashes at a frequency of once every 1 to 2 seconds, it is normal. This indicates that the vehicle's engine has entered the anti-theft mode, and the engine immobilizer is functioning properly. This is a normal phenomenon, and the owner does not need to deactivate it. Moreover, the power consumption is minimal, and it poses no issue for the battery. Below is a detailed introduction to the car's anti-theft system: 1. Anti-theft authentication: For vehicles with a keyless system, pressing the unlock button or the keyless button on the driver's side door handle will open the door and deactivate the vehicle's alert status. When the power is switched to the ON position, the engine immobilizer authentication is successful, and the anti-theft indicator light on the dashboard will turn off. 2. Automatic locking: After unlocking, if any door, window, or ignition switch is not opened within 30 seconds, the doors will automatically lock, and the vehicle will re-enter the alert status.
The Toyota RAV4's lock indicator light keeps flashing non-stop, and I think it's mostly due to the anti-theft system acting up. Normally, the light flashes a few times to indicate the car is locked, but continuous flashing is abnormal. Common causes include doors not being closed tightly, the trunk latch not properly engaged, or weak signals from low key fob battery. Once, I encountered this issue and found the driver's door wasn't shut properly—closing it firmly stopped the flashing. If the key fob is experiencing interference or the surrounding electromagnetic environment is noisy, errors can also occur. I recommend checking all doors and the trunk, and trying a new key fob battery. Don't take it lightly, as continuous flashing could escalate to anti-theft system failure, making the car vulnerable to theft. It's best to promptly visit a reliable repair shop to inspect the control module and prevent potential hazards from worsening—safety on the road comes first.
