How often do you need a "safe guy" to come to your house for service? I've got a Remington safe that is about five feet tall. I've had the safe for probably 10 years. I had someone out here three times and I think I might need service again. My safe might get opened maybe three times a month. Certainly not hard use. It is now getting to the point where I need to do four or five attempts to open it before it will work. So I'm thinking possible service again. Does this sound normal to you folks, or should I be able to go much longer between services considering that it hardly gets used?
