If you've ever stood outside in the cold after locking your keys in your car, you know how valuable the services of a qualified locksmith can be. Homeowners, businesses and government agencies use locksmiths to repair and open locks, make keys, change locks and safe combinations, and install and repair safes. Qualified locksmiths may find employment opportunities working for local locksmith and security companies, roadside assistance services, and building contractors. Becoming a locksmith may be a good choice if you're looking to start your own business as many locksmiths are self-employed.

An online certificate program in locksmithing typically includes coursework in areas like:

• Locksmithing tasks and tools
• Keys and key cutting
• Lock and deadbolt installation and lock picking
• Combination and electromagnetic locks
• Automotive locks and alarms
• Electronic security systems
• Passkey systems
• Operating a locksmith business

Many states require locksmiths to pass a licensing exam to become certified. Check with your state's licensing agency to find out the specific requirements in your area.
