6. Maintenance
The primary maintenance for your remote key fob involves battery replacement.
Battery Replacement
The remote uses a CR2032 lithium coin cell battery. When the remote's range decreases or it stops responding, it's likely time to replace the battery.
- Open the Fob: Carefully pry open the remote's casing. There is usually a small notch on the side where you can insert a flat-head screwdriver or a coin to gently separate the two halves.
- Remove Old Battery: Note the orientation of the old battery (positive (+) side up or down). Remove the old CR2032 battery.
- Insert New Battery: Insert a new CR2032 battery, ensuring it is placed in the correct orientation. It is recommended to use a high-quality battery from a reputable brand (e.g., Duracell, Energizer) for optimal performance and longevity.
- Close the Fob: Carefully snap the two halves of the remote casing back together until it is securely closed.
- Test Functionality: Test the remote to ensure it is working correctly after battery replacement.
