This is just the cost of opening and not the cost of having a locksmith on site (the service call), which is additional when you can't take the safe to a locksmith shop. Locksmithing is an art, and the cost of a locksmith generally indicates their level of experience, as well as the payment for their skill set. You don't expect to tip a locksmith, and it's not common for people to tip a locksmith who comes to change or re-lock their locks. An emergency locksmith who works 24 hours a day is likely to charge more than a locksmith hired to go out during working hours to change the locks.
