All cars are fitted with the standard shoulder belt. This belt goes over the shoulder and lap, offering maximum protection for the passenger. Seat belts do become subject to casual wear and tear; sometimes they can stop working altogether, making it dangerous for the driver and passengers. Fixing a problem with a seat belt buckle involves dismantling the seat belt.
Fully extend the whole of the seat belt to check for kinks.
Remove the bolt underneath the seat belt buckle. Hold the retractor straight and thread the seat belt out. Remove the seat in the car if you need to gain a closer inspection of the belt.
Use the screwdriver to unscrew the current buckle from the car.
Screw in the new buckle. Then thread the seat belt through the new buckle.
Reinstall the small bar underneath the buckle to hold it in place.
Pull the seat belt out to make sure it's working properly.
Reinstall the seat if necessary.
