A few locks have a policy to give you money, might want to check with your lock company.
There are a lot of hoops for that usually. Someone can elaborate if I miss the details BUT:
Usually have to have the police report, register within the week or two you bought the lock for the insurance, be able to prove it was locked properly. At that point, it is usually at their discretion if they will pay out.
Best bet for a campus bike is two fold: go to Third Hand, Once Ridden, Craigslist or the classifieds and find the cheapest ride that is comfortable. Make sure the lock you buy for it is worth at least 2-3 times more.
Second, park and lock the bike next to the expensive one the freshman brought from home that is locked by the frame with a wall mart cable lock.
