What to do about theft?

[kgzak]

This is located at our school. The problem is there is a master key to all our rooms and I don't know if the school would want to have the lock for one room different than the rest. We have told the administration and they will be an insurance claim filed and possible investigation. We are doing everything we can think of. I'll be talking with one of our teachers tomorrow to see if he has any more information on what is happening.
