Oklahoma Locksmith Practice Exam

When changing a Standard Group 2 combination, what should the technician do after dialing the old combination on the change mark?

1. Remove the lock from the door

2. Insert the key change from the back of the wheel pack

3. Reset the dial to zero

4. Lock the mechanism in place

The correct answer is: Insert the key change from the back of the wheel pack

After dialing the old combination on the change mark, the technician should insert the key change from the back of the wheel pack. This step is essential because inserting the key allows the technician to engage the locking mechanism that secures the combination against unauthorized changes. The key change is a crucial part of the process, as it validates the procedure being carried out and ensures the lock is ready to accept a new combination. Successful execution of this action allows the technician to proceed with resetting the combination safely. It is important to follow this specific order to ensure that the lock maintains its integrity throughout the changing process. The key effectively disables the old combination, allowing for modifications as per standard procedures in locksmith practice.
