The Body Control Module (BCM) of the Buick Envision is located inside the cabin, beneath the center console at the rear of the floor console. Access requires removal of the front passenger side footrest. Relevant information about the Envision is as follows: 1. Vehicle Design: Exterior: The 2020 Buick Envision features a more rugged and bold appearance. A new wing-shaped chrome trim runs through the LED wing-shaped headlights, widening the horizontal visual effect. The dynamic bumper surfaces and three-dimensional silver lower guard create a full and powerful front end. The rear also adopts a three-dimensional wing-shaped design, with chrome trim connecting the taillights, paired with integrated dual exhaust pipes to enhance the sporty feel. Interior: The 2020 Buick Envision continues Buick's signature high-end interior quality and introduces a newly designed 10-inch HD touchscreen for a more technological appeal. The vehicle also features front-row multi-function seats, adjustable and sliding rear seats, a large split central storage box, a heated steering wheel, and a two-piece panoramic sunroof. 2. Driving Performance: Powertrain: The 2020 Buick Envision offers two engine options: a 2.0T-SIDI direct-injection turbocharged engine paired with a 9-speed HYDRA-MATIC intelligent transmission, and a 1.5T-SIDI direct-injection turbocharged engine paired with a 7-speed DCG-PLUS intelligent dual-clutch transmission. The former delivers a maximum power of 191kW at 5500rpm, peak torque of 400N·m between 3000-4000rpm, accelerates from 0-100km/h in 8.2 seconds, and has a combined fuel consumption of 8.8L/100km. The latter produces a maximum power of 124kW at 5600rpm, peak torque of 250N·m between 1700-4400rpm, accelerates from 0-100km/h in 10.3 seconds, and has a combined fuel consumption of 6.6L/100km. All models meet the stringent China 6b emission standards.

The keyless entry module for the Buick Envision is typically located in the driver-side dashboard area, near the steering column. Based on my years of experience helping people with car repairs, finding it may require first removing the plastic cover of the footwell air vent, as engineers designed it for convenient key signal reception inside the vehicle. Be careful with the wiring during operation to avoid disrupting the connectors—if the module malfunctions (e.g., failure to lock or slow response), the most common issues are moisture or wear on the module contacts. Regularly checking for loose wiring connectors can extend its lifespan. For modifications, I advise against relocating it casually, as the factory setup ensures anti-theft system stability, and DIY issues may lead to costly dealership repairs. Another key point: the module’s placement also considers proximity to the central control system for seamless integration with the engine immobilizer. Avoid using it in damp conditions to prevent short circuits and bigger troubles.

As a car enthusiast, I find the keyless entry module of the Buick Envision quite interesting. It is mainly installed inside the door or near the rear trunk. I once opened the door to check it out—the module is hidden behind the inner door panel, facilitating quick recognition of remote signals and reducing latency. When modifying, be careful not to damage the antenna, as it can affect the unlocking range. I learned a tip from the forum: when cleaning dust inside the door, use a dry cloth to wipe the module connection points to prevent malfunctions. Additionally, this is linked to the vehicle's overall security system. For example, when the battery is low, the module might respond slowly, reminding the owner to replace the battery regularly. The design of its location allows for easy maintenance by the owner—don’t worry about it being hard to find due to a remote position. Just develop a habit of regular maintenance. If you find it difficult to handle, it’s better to consult a professional technician.

My Envision had a minor issue with the keyless entry before, and the mechanic told me the module is located under the dashboard. Simply put, it's behind the plastic cover on the left side of the steering wheel—just remove the screws and you'll see a small black box, which is the core controlling the key sensing. I once experienced a sensing failure, and cleaning the module fixed it. So for daily driving, remember to prevent water accumulation in the interior or stacking items that might squeeze it, as this can affect its lifespan. It's advisable to check the connection wires monthly to ensure they're not loose, avoiding sudden malfunctions that could disrupt your trip.
