- Check the buckle slot for debris, coins, or anything blocking the latch from seating fully.
- Remove any heavy bags or objects from the passenger seat if that's the seat triggering it.
- Try a different seatbelt buckle in the car to see if the chime follows the belt or the seat.
- Clean the buckle with a small brush or compressed air if debris is visible.
