Where is the anti-theft control box located in the Buick Excelle?

Buick Excelle's anti-theft control box is located at the lower left corner of the steering wheel, and the key induction coil on the steering column is the anti-theft module. Purpose of installing the anti-theft device: The main purpose of installing the anti-theft central locking system is to control the vehicle's original central locking, achieving the goal of remote lock/unlock operation. Function of the anti-theft device: The vehicle anti-theft control system integrates the anti-theft device with power windows and central door lock control modules for centralized monitoring. When pressing the lock button on the remote control, the central door lock system engages. When the system enters alarm status, the door windows will automatically rise to prevent users from forgetting to close them, eliminating concerns about rain, wind, or theft, thus providing convenience for users.
I've recently studied the Buick Excelle's anti-theft system, and the control box is indeed well hidden. Last time at the repair shop, I saw the technician remove the lower steering wheel cover, revealing a matchbox-sized black box connected to numerous wiring harnesses. This component is typically embedded in the left side of the dashboard's internal frame, near the center console. However, there might be slight adjustments between older and newer models – I've heard that post-2006 models have it shifted slightly toward the passenger side. Don't risk disassembling it yourself; incorrect wiring connections can easily fry the ECU. I remember someone in my car club forced open the trim panel, broke all the clips, and ended up with the entire center console creaking.
With over a decade of car repair experience, I know the location of the Buick Excelle's anti-theft box like the back of my hand. Look under the dashboard frame on the driver's side, specifically in the area about 30 cm above the accelerator pedal. You'll need to remove the plastic cover first. That aluminum box is usually fixed to the firewall insulation with very short wiring. Last time I worked on a 2007 1.6L model, I found the manufacturer had stacked the anti-theft device and airbag ECU on the same bracket. I recommend using a flashlight to check the gaps and confirm its position first - yanking it hard might break the antenna. If you really can't find it, go to a professional shop to read the fault codes; their diagnostic tools can directly locate the control box's signal source.
