Seat belts are fairly simple things and they have been the same mechanism for a long time, they have become more sophisticated with the addition on air bags, they actually have a system for locking them tighter in the event of a crash. But when the belt won’t buckle you can bet something has dropped in there not allowing the belt to latch in there. Take a look and try to fish what ever is in there out. many times it will be a coin. Many times you will need to stop by your service center and have the buckle removed to get the coin out.
