It can be a couple of different things causing the light to stay on. The most common is a sensor inside the seat belt buckle that will fail. The repair would be to replace the seat belt and the tensioner for the seat belt. The cost varies from model to model. Get the car checked by a shop with the right equipment to be able to diagnose the propblem 1st. This is just one of the most common problems we see. There are many other things it could also be. Downside to the light being on is that the air bag will not function with the SRS light on, so it becomes a safety issue as well.
