The method to replace the battery in a Golf car key is: 1. Locate the button on the top, press it, and pull out the mechanical key; 2. Insert a flat-head screwdriver to pry open the key cover, and when there is a gap, open it by hand; 3. Flip open the cover, remove the old battery, and install the new one. Taking the 2020 Golf Sportsvan as an example, its body structure is a 5-door, 5-seat hatchback, with body dimensions of: length 4351mm, width 1807mm, height 1574mm, a wheelbase of 2685mm, a fuel tank capacity of 50 liters, a luggage compartment capacity of 500 liters, and a curb weight of 1395kg.

Last week I just replaced the battery for my Golf car key, and it was actually quite simple. First, determine your key model—most use a CR2032 coin cell battery. When prying open the key casing, avoid using metal tools; instead, use a plastic card to gently wedge along the side seam. Be careful with the central clip on the Golf key to avoid breaking it. When removing the old battery, note its orientation, and ensure the new battery is inserted with the positive side facing up before gently snapping the casing back together. The whole process takes about 5 minutes—just remember to test the lock and unlock functions afterward. If you're still unsure, you can search online for Golf key disassembly videos to follow along. A new battery costs just around 10 yuan, saving you dozens compared to going to the 4S shop.

I've changed the Golf car key battery three times, so I have some experience. First, prepare a CR2032 battery and a plastic pry tool (your fingernail can work if it's strong enough). On the back of the key, you'll see a thin seam. Start prying from the end with the VW logo, using finesse rather than brute force to avoid scratching the plastic casing. Once opened, the silver button on the circuit board is the battery—use small tweezers or a toothpick to pop it out. Key point: Make sure the battery's orientation matches the original. Once, I installed it backwards and the key stopped working, almost leaving me stranded. After installation, press the casing until you hear a click to ensure it's properly seated. Finally, test the key by pressing buttons to check the light response. If the remote range is restored, you're all set.

Replacing the Golf key battery involves four steps: Purchase a CR2032 battery, commonly available at supermarkets; use a coin to twist open the casing along the groove on the side of the key; remove the old battery, paying attention to the positive and negative orientation; insert the new battery and snap the casing shut. Avoid using metal tools to scratch the circuit board during the process. After installation, test the car lock response before starting the engine. I've taught this method to several friends, and they all succeeded. The new battery typically lasts about two years. When you notice the remote becoming less responsive, prepare in advance to avoid last-minute hassles.
