This place is awesome! They have helped me twice when my car key got stuck in the ignition and wouldn't turn. They replaced the ignition cylinder. I had to use another company in between my two times and was very dissatisfied and that experience made me realize how much better Dupage Security Solutions is. Dupage Security Solutions technicians are responsive, timely, affordable, professional, thorough, patient, and they explain everything step by step, tell you your options, and get your permission before moving forward on another step. I called this most recent technician "my hero" and he humbly smiled and went on his way. :) They aren't 24 hours (that's why I had to try another company- next time I will wait!) so keep that in mind. They do many other things- check them out at www.dupagesecuritysolutions.com. read more

I really appreciate the professionalism and understanding that was extended by these guys. I had to change the-not the locks-the whatever you call them in my parents home and I called Ace Hardware for a recommendation. They sent me to DuPage Security System and I felt like I was in excellent hands. Anyone who pets my dog gets extra stars. Thank you! read more

So Home Depot made me two sets of keys neither worked, and ace hardware made me three sets of keys didn't work. I went over to du Page security and they were so professional and smart and made me keys that fit my luck. I am so happy because I don't have to change my deadbolt. Thank you so much for always being there for the community. Great service great people read more

They changed my locks for me. Extremely professional. They were on time, polite and my quote was accurate. Also efficient and speedy service. read more

After purchasing a home that had years old locks, I called DuPage out to rekey the locks however, the knowledge that the technician had and shared with me led me to purchasing much higher quality products. It was installed effortlessly and I couldn't be happier. Highly recommend this place and will be going back to them in the future for other needs- their safe selection is amazing!

Horrible customer service and attitude... Instantly turned me down saying no one could help me but the locksmith who "made the special security key" i tried to at least ask a few questions but immediately after his comment he just walked away and left me there. On the flip side no one should have to deal with this when there's 3 places with 5 min to get a key cut. I went 3 min down the road to Keyway Lock & Security Company was greeted politely explained what DuPage Security claimed they laughed and had me out in 2 minutes with 2 of these "special security keys". read more

I just moved to town and wanted to get my locks re-keyed. I called Dupage and tried to work something out for the same day. We couldn't get our schedules to agree, but they were nice about rescheduling for the following day. Dave called about 15 minutes before he would arrive, and he was right on time. He came in and quickly assessed the situation, re-keyed three cylinders, and was out of here in about 20 minutes. My dog was obnoxious (not mean, just loud), and he was great with her. The cost agreed perfectly with the estimate. Dave was prompt and professional. I highly recommend them and will call them again when I need them! read more

DuPage Security Solutions made re-keying the older locks on the home we just moved into extremely easy. The process literally took 15-20 minutes onsite and the locksmith who came out for the job was so knowledgeable and helpful in letting me know my options. One less thing to worry about as we get settled in. I would highly recommend. read more

Very professional technician! All my locks in the house work! I would definitely recommend this company and use them again.

Poor service. Treated almost as a non-human. In their own words I was a red-flag. Eeek, do not trust them. Unfortunately they were not even friendly enough to give me a quote on a very simple task, or project. Almost like a homework assignment. Do not use them or trust them. I even have a copy of the email as proof of what I am saying to be true, not making this up by any means. read more

Our experience with Dupage Security Solutions was truly outstanding. From their first visit to determine the scope of work to be performed through installation everything they did was accurate, timely, friendly and reasonably priced. The installer -- Dave -- did exceptional work and was completely polite and flexible in working around our busy schedule. I contacted several locksmiths and my impression was that these guys were exactly what I needed from a security standpoint. I also visited their store in Addison and walked away thinking they were the "real deal" I was looking for. I am still amazed (and grateful) each time I turn the key to one of Dave's newly installed locks and I hear the crisp little "click" that tells me it was installed perfectly - no rubbing, no off-center, no nothing - just perfect! I'm a long time DIY'er but I recognize that in some areas, especially home security, going with a professional makes more sense. A simple measure of how I feel about a project is: Given the same circumstances, would I do it the same way again? In this case, using Dupage Security Solutions, the answer is a resounding and confident "yes." read more
