We have had two small issues since then (not to do with the quality of work, just minor snafus) and Don responded to me right away and helped me fix the problem.

I had an excellent experience with Chicago Locksmith and was extremely pleased with the entire…read moreprocess and final results. Because my project involved a custom door replacement that required condo association approval, custom ordering, painting, lock placement, and installation, there were several phases involved. Throughout it all, the team remained professional, responsive, organized, and attentive to detail. Walter, the locksmith technician who handled the project from beginning to end, did an outstanding job. His workmanship, professionalism, and attention to detail truly stood out, and the finished result exceeded my expectations. Chicago Locksmith is lucky to have someone such as Walter that is extremely skilled, professional and pleasant to deal with. I also want to recognize the Chicago Locksmith office staff for their excellent customer service and communication throughout the process. Everyone was courteous, helpful, and a pleasure to work with. Overall, I highly recommend Chicago Locksmith for their professionalism, quality work, and outstanding service.

I sent out a free estimate request via Yelp and received far too many responses…read more My primary, evidently probable Yelp Elite and Yelp All-Star review are based on Yelp and my communication with the owner Shay. Perhaps he is of Irish heritage, I never had the opportunity to find out 1) I have seen over 300 photographs of his work This man is the very BEST if you are only looking for a handyman or have no assistance from even an essentially useless husband in the paint or a long hair clogged shower drain 2) Shay is a LIAR I appreciate that he was willing to drive out to The suburbs of Chicago from all the way East in Logan Square His estimate is NOT free as Yelp guaranteed He requires photographs (easy peasy) of the locks as well as *$45* to even come out to take a look He broke the Yelp Guarantee right there Chicago Locksmiths should be banned from Yelp same as nobody should have voted for Trump. There were zero good choices but at least ond was NOT a babbling dementia suffering 90 yeat old 3) Shay claims the his primary concern is home and auto safety If that were actually true then with photos in hand he has zero reason to have a $45 fee to take a look I have zero reason to take issue with Shay - especially his quality of work All that I know is that Shay LIED to Yelp in order to gain business and if that works for him, then I do not give a fxck I shall not be used I have Elite and All-Star status that I EARNED with Yelp and followers Every single one of my Yelp reviews are shared with Google I sincerely hope that my review discourages anybody and everybody from hiring Chicago Locksmiths
