How to Replace the A6 Key Battery?

[DelMalia]

First, remove the mechanical key, then use a rigid pry tool to gently open the key casing along the seam, allowing access to replace the battery. Here are some relevant details: 1. The battery inside the remote key typically lasts 2 to 3 years. Once the battery is depleted, it should be replaced immediately to avoid inconveniencing the vehicle owner. 2. Some vehicles come equipped with a keyless start system. For these cars, the owner only needs to carry the remote key inside the vehicle, enabling the car to detect the key. At this point, pressing the start button while depressing the brake pedal will start the engine. 3. Vehicles with keyless start have a designated area inside the car specifically for key detection. If the remote key battery is dead, placing the key in this detection area allows the car to still recognize the key, enabling the owner to start the engine.
