How do I replace my key fob battery safely at home?

Replacing your key fob battery is usually quick and doesn’t require programming. Using a small flat tool or screwdriver, carefully open the case, swap the old cell for the new Deluxe CR2450 with the correct polarity, and snap the housing back together. Dispose of the old battery responsibly.

• Work on a clean, flat surface and keep tiny screws or clips secure.
• Observe polarity (+/-) when inserting the new CR2450 cell.
• If your fob has additional electronics, avoid touching circuitry directly to prevent static damage.

Will I need dealer service or reprogramming after replacing the battery?
