2 Answers
Ford Focus car key battery replacement method is: 1. Insert a flat-head screwdriver into the gap on the logo side of the Ford Focus key, then pry upwards to open the logo panel; 2. Gently tilt the key to let the old battery slide out, then replace it with a new one; 3. After replacement, securely close the cover. Taking the 2020 Ford Focus as an example, it belongs to the compact car category with body dimensions of: length 4378mm, width 1810mm, height 1468mm, and a wheelbase of 2705mm. The 2020 Ford Focus is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 122PS, maximum power of 90kW, maximum torque of 153Nm, and is paired with a 6-speed manual transmission.
I often change the battery for my Focus key myself—it's simple and saves money. There's a small gap on the back of the key. Use a thin tool like a flathead screwdriver or a hard plastic card to gently pry open the casing, but don't use too much force, or it may crack. Once opened, you'll find a coin cell battery inside, usually a CR2032. When removing the old battery, note the positive and negative positions—most have the positive side facing up. When installing the new battery, align it correctly to avoid reversing the polarity. I recommend using genuine Panasonic or Sony batteries for durability, as knockoffs can cause issues. After placing the new battery, close the casing securely, ensuring the clips snap into place. Then, test the lock button on your car—it should light up to confirm success. Lay a cloth on your work surface to prevent small parts from rolling away. With a few tries, you'll master this quick fix, saving dozens of dollars on shop fees while gaining a handy skill. I suggest checking the battery annually to prevent sudden failures.
