The first task for the technicians are to gather all the locks that need to be re-keyed in area they start at. Typically, they start at the gas station because it is a high traffic location. They want to have the new locks and keys in place for the employees to access.


The technician removes the pins of the cylinders and reads a blueprint to know which new pins to add. It is important to replace the pins because they can get worn out over time.
