Jeff and Kim Beckmann opened J&K Lock Service and Supply in June of 1987. The following month Jeff's brother, Steve Beckmann, joined in on the adventure. Built on a core foundation of customer service, J&K began as a small "lock and key" shop serving the Greater Madison Area. The company ventured into the electronics security world by the mid-1990s as their business continued to grow.Today, J&K prides itself on being efficient in a vast majority of residential and commercial security services. Our company remains family owned and operated over 25 years later, while still abiding by the same core principal it was founded upon-serving the customer.

Recently our HOA building had challenges with the existing key fob system that was originally installed by J&K many years ago. It isn't that the system wasn't good, it was old and beginning to fail as technology often does. We worked with J&K to get quotes on a new system that was much more reliable, supportable, and future-forward. The installers were professional and answered any and all questions we had, they were able to solve any issues that arose, and the system works much better than the prior system did.
They did a neat job and cleaned up their messes where they were made and ensured we have a fully working system before they were done. I cannot recommend the quality of work done by this team enough.

****READ THIS BEFORE CALLING THEM! If you want true professional, reliable, knowledgeable service then give J&K a call! From assisting us in choosing the correct applications for our doors to timely and professional install - J&K's service was just simply incredible! We have worked with other lock companies before and can definitely say we will never work with anyone else again other than J&K! Give them a call you will not be disappointed. You will save your time and your money!
