5. Maintenance

Proper maintenance ensures the longevity and reliable operation of your key fob.

Battery Replacement

The key fob is powered by a CR2025 coin cell battery. When the remote range decreases or it stops responding, the battery may need replacement.

1. Accessing the Battery: Carefully separate the key fob casing. This may require a small, flat-head tool to gently pry open the seam. Exercise caution to avoid damaging the internal components or the casing.
2. Remove Old Battery: Locate the CR2025 battery and carefully remove it. Note its orientation (+/- sides).
3. Install New Battery: Insert a new CR2025 battery with the positive (+) side facing up, matching the orientation of the old battery.
4. Reassemble: Carefully snap the key fob casing back together, ensuring all parts are securely fitted.

Note: Some users have reported difficulty in opening the key fob to replace the battery. If you encounter significant resistance, consider seeking assistance from a professional to avoid damage.
