Combination locks are used to keep items safe. You may find them securing bikes and lockers at schools, offices, health clubs and recreational facilities. Combination lock boxes are also used to hold house keys during a house sale. Although you need to have a sequential series of numbers to open a combination lock box, not all lock boxes are fully secure from entry. Combination locks on doors may require electronic circuitry as well, which makes them more secure.

Skill level:
