The story begins in 1968. Dr. E.O. Thompson Sr., known as "Tom" since college, was an optometrist at Plymouth Optical in Winona. After a change in personnel, he had the local hardware store re-key the office lock. The new keys didn't work very well. Disappointed, and ever the perfectionist, he disassembled the locks and made it work better.
With more than 50 years of experience in the field, Tom's Lock Service offers efficient and outstanding service in the shop or on the job. If stranded, we come to you with one of our full-service rescue vans to do the repair on site. We offer a wide variety of key chain accessories, including, but not limited to, key caps, bottle openers, sports teams, lanyards, and wrist bands.
Vials of tear gas, shown on the right, were commonly used in safes beginning in the 1920s and ending in the early 1950s. The gas tubes were meant to prevent theft by breaking upon forced entry into a safe. The non-lethal gas emitted from a theft makes breathing difficult and severely irritates the eye, causing tearing, pain, and occasionally blindness.
Has been a locksmith since 1977 and owner of Tom's Lock Service since 1983. He's a graduate of Winona State University with degrees in Business and Economics. Emerit is a Winona native and lives here with his wife and three daughters. He loves cruising in his convertible, drawing with pen & ink, woodworking, and (once again) loves cruising in his convertible.

In addition to the above list of "Good quality" "Good value" "Professional" and "Responsive' ... the Incredibly pleasant customer service REALLY impressed me ... a RARITY from many businesses or independent 'contractors'. Tom's Lock Service hasn't been in business for over 50 years without earning it. Thank You!
