A higher-grade combination lock often picked by locksmiths is the single dial padlock. These locks are often found on school lockers, gates, and engraved into safes. The dial is hand turned clockwise, then counterclockwise, then clockwise again with the correct number combination until the lock opens. These locks frequently are found to jam, and a locksmith is called upon to open them. locksmiths can manipulate these combination locks by drilling or rapping them with a tool (such as a hammer). Safe locks may require a locksmith's specialized tools in order to gain access to the safe. Homeowners and business owners will oftentimes have locksmiths come out to their location to repair or replace these combination locks with an upgraded lock. Whether an upgrade or new locks are needed, calling a locksmith for assistance is always a good idea.
