To open and replace the battery in a Volkswagen Golf car key, follow these steps: 1. Eject the mechanical key and insert a coin or metal pry tool into the slot where the mechanical key is housed; 2. Apply force to pry open the outer shell of the remote key; 3. Remove and replace the battery. The Golf is a compact car produced by Volkswagen, with body dimensions of 4296mm in length, 1788mm in width, and 1471mm in height, and a wheelbase of 2636mm. The 2021 DSG Golf features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 116PS, a maximum power of 85kW, and a maximum torque of 200Nm, paired with a 7-speed dual-clutch transmission.
Recently, the battery in my Golf key fob died, and I successfully replaced it myself with no issues. There's a small gap on the back cover of the key—just gently pry it open with a coin or a small flat-head screwdriver. Inside, you'll find a tiny CR2032 coin battery. Carefully remove the old battery without damaging the contacts, then insert the new battery with the positive side facing up. Make sure the model matches CR2032, or it won't work. Snap the back cover shut firmly until you hear a click, then test the lock/unlock buttons to ensure they respond normally. The whole process takes just a minute or two, saving you the hassle of visiting a mechanic. I recommend buying a few spare batteries in advance from Taobao or a supermarket—Golf key fob batteries typically need replacing every year or so. Doing it yourself is both cost-effective and quick. Perform the replacement in a dry environment, and avoid getting water on your hands or tools to prevent short circuits.
I've replaced the Golf key battery several times. First, locate the small latch at the tail of the key, and gently pry it open with a fine tool like a toothpick—avoid using excessive force to prevent cracking the shell. Remove the old battery, remembering it's a CR2032 model, and clean any dust from the contacts to ensure conductivity. Place the new battery in the original position with the positive side facing upward, then close the cover and press firmly to test functionality. If the buttons don't respond, the contacts might be oxidized—lightly wipe them with a dry cloth. The entire process is simple, efficient, and saves both time and money. The key is to avoid buying the wrong battery model—CR2032 is widely available. It's advisable to work in a well-lit area to prevent losing small parts and to note the replacement date each time for tracking the next change.
