If someone keyed my car and I file a claim, will that make my insurance go up?

I would recommend getting a repair estimate first. This way you will have more information to base your decision on. The damage would probably be considered an act of vandalism so you'd have to pay your comprehensive deductible before the insurance company would pay for any repairs. A comprehensive claim normally doesn't impact your rate the way a collision claim would (collision is the coverage you use if you're in an accident), so I wouldn't be too worried about your overall rate. On average, your first comp claim will raise your premium by 4.35%, or $64 per year. If you can afford to fix the damage yourself then I would probably try to avoid filing a claim, but that decision is completely up to you. Get some more tips on whether or not to file a claim here.
