About Us

Tom Thilgen, owner of US Key Service in Arizona

US Key Service has a long history of providing auto locksmith services. In 1972, Bill and Olga Thilgen started their very first locksmith company based out of southern California called Arkco Security Co. During that same year Tom Thilgen, Bill and Olga’s son, came on board and the family unit was then created.

In 1973 Arkco Security Co. was awarded a Southern California Auto Club contract to provide their members with lockout and locksmith service. Arkco added 6 more employees and 7 more service vehicles to accommodate the growing business.

In 1997, Bill and Olga Thilgen retired and Tom Thilgen continued to run the company until 2007 when it was sold. Meanwhile Tom had started his own company in 2005, American Lock Service Enterprises LLC in Phoenix, AZ. He continued to run both companies until 2007 when Arkco Security Co. was then sold.

In 2007, Tom moved to Phoenix and created a sub company called US Key Service. Later that year Tom was awarded a contract with Arizona Auto Club to provide it’s members with lockout and locksmith service. US Key Service continues to providing it’s customers with the latest automotive lock and key service.

”After explaining to the company that I had lost my car key, they arrived at my home within an hour and presto chango, I had two new keys made and had the extra one programmed. The level of customer service was outstanding. Not only are the prices reasonable, I even received a AAA discount!!!! I would recommend US Key Service in a heartbeat.”
