How to Replace the Key Battery for Volkswagen CC?

[JordanAnn]

The method to replace the battery for Volkswagen CC key is as follows: 1. Place the remote key facing upwards, use a small flat-head screwdriver to gently pry into the middle of the gap. The key will separate slightly, creating a gap of about 2mm. Then, carefully separate the key into two parts to access the battery compartment. The prying action is intended to release the hook from the groove in the red circled area shown in the diagram. 2. Gently separate the key along the middle gap, then remove the old battery and replace it with a new one. Below is additional information: The basic principle of the Volkswagen CC remote key is that it emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator (motor or electromagnetic coil) performs the locking/unlocking action.
