What is the reason for the anti-theft light flashing in a 2007 Focus?

[DelDonovan]

If the car's engine anti-theft light flashes at a frequency of once every 1 to 2 seconds, it is a normal phenomenon. This indicates that the vehicle's engine has entered the anti-theft mode, and the engine anti-theft system is functioning properly. This is normal and does not require the owner to deactivate it. Moreover, the power consumption is negligible and poses no issue for the battery. Precautions for using the engine anti-theft system: 1. When inserting the key into the ignition switch lock cylinder and turning it to the "ON" position, avoid placing items with strong magnetic fields near the ignition switch lock cylinder. 2. Do not expose the key to extremely high or low temperatures. 3. Avoid dropping the key on the ground carelessly. 4. Do not apply heavy pressure to the key.
