What is the manual anti-theft deactivation method for the 12th-gen Focus?

Locate the in-car fuse box, typically found in the engine compartment or glove compartment. Follow the instructions to find the anti-theft system computer fuse and remove it to cut off the power supply. If there is no fuse installed, locate the car anti-theft system computer under the steering wheel and directly unplug the power cable connector. The anti-theft system will naturally deactivate when power is disconnected. If neither of the above methods works, you can open the trunk, then close and lock the car doors. Within 10 seconds, insert and remove the key more than 6 times to clear the ID stored in the key. Manually lock the driver's side door using the switch, then use the remote to lock the car once. This allows you to input a new ID into the computer. After opening the driver's side door, the anti-theft system will be deactivated.
I encountered the anti-theft lock issue while driving a 2012 Ford Focus manual transmission. That time, after the car stalled, the alarm suddenly went off and it wouldn't start. I quickly found the original mechanical key, inserted it directly into the driver's door lock, turned it open, and got in. Inside the car, I patiently turned the ignition switch to the power-on position without starting the engine, waited a minute or two for the system to recognize and release itself. Later, I checked the manual—Ford's anti-theft system resets and syncs the battery this way. Prevention is better than a temporary fix. I always keep a spare battery in the car and regularly check the key's sensing distance to avoid it being too far. Driving safety is paramount. If this trick doesn't work, it's best to call after-sales support to avoid damaging the circuits by messing around.
