Residential Locksmith

Elmer & Son Locksmiths began in 1941 in what was originally the home that Elmer and his family lived in. We are still located in the exact same spot, and just like the times have changed so have we. The house was eventually converted into a modern locksmithing business, complete with a 1200 square foot showroom where we have over 50 new and used safes on display, along with commercial and decorative lock hardware. The original storefront was converted into the only museum in the region dedicated to locks and safes.

We have become the security hardware center for the Chicago Southland and Northwest Indiana communities. Our customers include residential, commercial, and industrial. We are proud distributors for some of the top manufacturers in the security industry. Including Schlage locks, LCN door closers, Von Duprin exit devices, Locknetics access control hardware, Medeco high security locks and Mesker hollow metal doors and frames.

At ESL we believe that customer service is the “key” to making a contract job run smoothly. What sets us apart from our competition is you only deal with one person for the entire project. From estimating to project managing it’s always that same employee. Unlike some of our competitors which have separate departments for estimating, detailing, purchasing and project managing that can make it difficult to find who you should be directing questions to. We know its much easier dealing with one person from the beginning to the end.

Another item were very excited about is our door frame and hardware schedules. We’ve been told by contractors and architects that its one of the easiest they ever had to review. Door openings are laid out clearly with elevations and hardware all on the same page. Please check out a sample of one here
We also have a 6000 square foot warehouse, located about five blocks away from our office, where we stock all our hollow metal material. We carry many sizes in stock, but if there is that odd size you’re looking for we can get most anything in about 2 weeks
