The method to replace the battery in a Malibu XL key fob is as follows: 1. Press the button on the left side of the key fob and pull out the mechanical key; 2. Use the mechanical key to pry open the outer shell; 3. Remove the old battery and replace it with a new one. Taking the 2021 Malibu XL as an example, it belongs to the mid-size car category, with body dimensions of: length 4933mm, width 1854mm, height 1472mm, wheelbase 2829mm, fuel tank capacity 55l, and curb weight 1430kg. The 2021 Malibu XL features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 169ps, maximum power of 124kw, maximum torque of 250nm, paired with a 9-speed automatic transmission.
Replacing the battery for the Malibu XL key is actually quite simple. I've done it several times myself and now I'd like to share my experience. You'll need a small screwdriver or a nail file—these key casings usually don't have screws, so you can just pry it open from the edge with the tool. Be careful not to use too much force to avoid damaging the plastic shell. Once opened, you'll see the battery compartment inside. The common battery model is a CR2032 coin cell. When removing the old battery, remember the orientation (positive and negative sides), and make sure not to install the new battery backward. After assembly, test the key buttons to ensure they respond normally. If it still doesn't lock or unlock, the battery might be installed incorrectly, or there could be another issue with the key itself. I recommend checking the key battery life once a year to avoid failures at critical moments. By the way, these electronic key batteries are very cheap online—you can get several for just ten yuan. Keeping a few spares in the car is super convenient.
