To replace the key battery for Golf 7, follow these steps: 1. Open the mechanical key and hold the car key vertically; 2. Use a screwdriver to insert into the gap where the key retracts; 3.

The Golf 7 is a compact car with body dimensions of 4255mm in length, 1799mm in width, and 1452mm in height, with a wheelbase of 2637mm and a fuel tank capacity of 50 liters. It is equipped with a 1.6L naturally aspirated engine, delivering a maximum power of 81kW and a maximum torque of 155Nm, paired with a 6-speed automatic transmission.
I've been driving for over a decade and have replaced many key fob batteries. For the Volkswagen Golf 7 key, the process is actually quite simple. First, locate the small notch or button on the key, usually near the keyring, and push it open with your thumb, or gently pry open the casing using a thin plastic card or a small screwdriver. Avoid using metal tools to prevent scratching the circuitry. Once opened, carefully remove the old battery, making sure it's a CR2032 coin cell with the positive (+) side facing up. You can buy new batteries at supermarkets or auto parts stores. Insert the new battery, gently close the casing until you hear a click to ensure it's properly seated. Finally, test the lock and unlock functions to confirm they're working. Last time I replaced mine, I used a multimeter to check the old battery's voltage—if it's below 3V, replace it to avoid sudden failure. I always keep spare batteries in the glove box for emergencies.
