Tom Tusing started his locksmithing career in 1984. Seeing a need in the automotive side of the industry, he opened The Car Openers, Inc. and specialized in automotive locks. He has been making keys for cars for over 35 years. During this time, as car locks became more intricate, he developed THE DETERMINATOR TOOL for decoding car locks which has been used in the locksmith industry for over 20 years. Tom also created a HIGH SECURITY KEY ORIGINATION MANUAL with over 500 pages of steps needed in making laser type keys. In 2015, with Greg Chambers and a few others, THE DIAGNOSTIC BOX USA was created.
