About Locksmith Doctor Company

Locksmith Doctor Company is a family-owned locksmith business serving West Chester Township and Southwest Ohio. Jim Lang, the owner, has been a professional locksmith since 1976 — nearly 50 years before most of his competitors opened their doors. He is bonded, insured, and has trained over 25 locksmiths throughout his career. When you call Locksmith Doctor Company, Jim answers the phone himself.

How It Started

Jim’s path to locksmithing started with his brother. When his brother got into trouble in high school, their father bought him a correspondence course in locksmithing. His brother became a pipefitter. Jim kept the course — and never looked back.

That decision in the 1970s launched a career that has supported Jim through college, through raising a family, and through some of the most meaningful work of his life. Over five decades, he has worked with some of the best locksmiths in the industry, trained over 25 professionals, and earned an MBA that he applies to running his business with the same precision he brings to every lock. He has seen it all — from elderly customers locked out in the cold wearing only a bathrobe, to large companies with over 500 employees upgrading their entire security infrastructure.

How We Work

Jim operates by a simple standard: give honest estimates, do the job right the first time, and charge nothing if you cannot help. That last part is not a marketing line — it is a policy. As Jim puts it: ‘I never got a participation trophy. If I do nothing, I charge nothing.’

Before every job, Jim reviews the challenge over the phone and will tell you honestly whether he can help. If he cannot, he will refer you to another reputable locksmith. When he arrives — on time 90% of the time — he introduces himself, gets to work, and does not leave until the job is done correctly. He provides honest estimates over the phone, something most locksmiths in the area refuse to do.

Trusted by Property Managers and Commercial Clients

Jim has built long-term relationships with property managers, office facilities teams, and commercial property owners throughout Southwest Ohio. He understands the regulatory demands that drive commercial security decisions, and he brings the same honest, no-nonsense approach to a 500-employee office building that he brings to a single-family home rekey.

A recent example: Jim rekeyed the locks in a new school under construction, upgrading its entire security system over approximately two months. The school opened its first year with a safe, dependable system in place — and the confidence that comes from working with a locksmith who has been doing this since before most of the staff were born.
