    Having quality security was a major priority when we established our new Headquarters in Evanston…read moreIllinois- as our team serves more the 1,600 youth and reaches more than 4,000 family members each year through afterschool and summer learning programs, clinical counseling, street outreach, and parent engagement programs. We required a system that was easy-to-use but delivered quality surveillance footage. The system was designed with panoramic or 360-degree cameras which reduced the total amount of cameras needed to cover key areas and allowed for the beauty of our facility to shine in which we were awarded Excellence in Design for New Construction at the 2017 Design Evanston Awards. Having Umbrella Technologies on the construction and planning team was of great value to our organization and after the system was turned over to our administrative team they were responsive and continued to answer all of our questions. We have on-going training planned with them & are very thankful for the video surveillance system they designed which serves to keep our staff, children and families focused on what matters.

    I've been working with Umbrella Technologies for nearly 2 years. Whenever I need something I email…read moreor call the COO and Founder Thomas Carnevale. He has always taken the time to help us with whatever we needed. On multiple occasions he took the time to do online demonstrations on their products and answer any questions that we may have had. They also provide advice on camera placement and what materials will be needed to make them operational. Thomas also does not try to up-sell or try to sell you things you don't need. He is honest with his evaluations and his quotes. Umbrella Technologies and Thomas have earned our business for all future camera purchases and I'd recommend them to other colleges or universities for Campus Security Services.

    My task in progress because my application is more complicated than normal. I needed an automotive…read moreremote key card. I shopped around but the most value was ordering it online from an automotive remote site. I interacted with Adam and he was able to show up on the early weekend morning. His text are professional and clear, & he included pictures. Mazda even as far back as 2005 (car was delayed as released as an 2006) used a key card. There is a chip in the card and one in the valet key. Mazda blank metal doesn't have all the slots cut into the blank either. Getting the car to go into reprogram mode didn't work because the console said I need two "keys." However there is a chip in both the medal key and card. So one transmitter set will work, or should have. He drove an hour back and forth to get the other generic key and had to modify it with a Dremel rotary tool so that the key would have tolerance to get through the tabs on the ignition. That didn't work and he is coming back next week to try again with just another chipped key. Didn't charge a trip fee for making a round trip, nor for the generic key that didn't work. I will spread the word within the MazdaSpeed group so they can get help if the elect to get the Mazda key card instead of generic. At least have one original card and one generic real key. At this point I elected to tow it to Mazda DG for them to try with my key. Because if I buy theirs, its considered an "installed electronic part," and they won't accept returns. Too risky for $400. If they can do it I just pay for 1/2 hour of programming. Worst case I have to buy their key, mine is also OEM (not eBay/Amazon). His company slogan should be either 'The Locksmith from Lockport,' or 'The Lockport Locksmith.'

They didn't work and I spent HOURS driving back and forth to have them try again, and ultimately to return them), Mark made copies of the key quickly and they worked! and when we needed some springs in our lock fixed, Mark was responsive! He told me he would arrive in about an hour, and about ten minutes out gave me a courtesy call to let me know he was close by. He not only fixed the lock, he also tightened up the screws and the screen door (that would slam shut previously). Mark was courteous, kind, professional and knowledgeable throughout the whole experience. Definitely going with Mark again anytime we have any key/lock needs! Thank you!

    I highly recommend Chicago Locksmiths. Their level of customer service and communication is…read moreexcellent. I called them hoping for a same day appointment. It was late in the day because the original company I called was a no-show. Chicago Locksmiths said they could do it and gave me a same day time window. Excellent communication: The technician called me at the start of the time window to tell me he was on another job, but would be there within 2 hours. This allowed me to get on with my day rather than waiting by the window/the phone (as the other company had left me to do all day). The technician then called me when he had finished the previous job and gave me a time frame of when he would get to me. As it was quite late I decided to reschedule for the next day. The same evening Chicago Locksmiths called me to confirm a next day appointment time. On the morning of my appointment the new technician called to say he was on his way with an ETA for arrival and called when he reached me. The communication was excellent and meant I could do other things because I knew Chicago Locksmith was keeping me updated on the status of my appointment. For the appointment itself, the technician was great. Explained everything, gave me advice on one of the doors which was coming loose off the hinge. Re-keyed my lock quickly and cleaned up afterwards. I will certainly use Chicago Locksmiths again. Great service, and impeccable customer communication!

    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
