Precautions During Replacement

While replacing the battery, I made sure to handle the internal components carefully and avoid touching the battery surface with bare hands to prevent corrosion. Keeping the fob clean and dry during the process also ensured better performance.

Disposing of Old Batteries Responsibly

After replacing the battery, I made sure to dispose of the old one properly at a recycling center or designated battery drop-off point. This helps protect the environment and follows local regulations.
