[BrooklynLynn]

Here are the steps to replace the battery in a Volkswagen car key: 1. Prepare the Volkswagen Lavida car key. 2. Separate the smart key from the mechanical key by pulling the key apart with your hands or using a screwdriver to pry it open. The screwdriver should be inserted into the gap where the key retracts. 3. Use your hands to separate the part with the circuit board from the part with the battery in the middle of the key. 4. After separation, carefully remove the old battery from the panel and replace it with a new one. 5. Finally, reassemble the key by reversing the previous steps.
