Customer Testimonials

Forget about all of those corporate cookie cutter businesses out there that seem to care more about making a buck than the quality of service provided for their customer - Nonstop Locksmith blows all of them out of the water.

With two locations (and one lab location) in Chicago, Nonstop Locksmith exists to keep the customer satisfied. They are prompt, efficient, and friendly. They aim to please and care about their community. They cover everything from locks, intercoms, safes, doors, to key copies (and much more). With amazing prices it almost feels like robbery! With such excellent service at an affordable cost it's hard to imagine why we would ever settle for anything less.

Thanks Nonstop Locksmith, we need more businesses like you!

Absolutely outstanding. These folks are professional, courteous, clean, responsive and really knowledgeable. I needed a full intercom and doorbell replacement; my one requirement was to use the existing wiring. I did not want to open any walls. They came to my house (on time) surveyed the existing non-functioning system, recommended and priced a new system and mapped out the wiring. The new system arrived on time and they called me (I did not have to chase them) to schedule the installation. The new system went in smoothly and works really well. The price was actually lower than the estimate as they were able to eliminate some parts. I very highly recommend these folks for simple or your most complex job, they know their stuff.

Nonstop locksmith had very fast, friendly and effective service. I got assisted by a store technician by the name of Gloria. She was very helpful and was very concerned with the job at hand. I would definitely recommend this locksmith to anyone who’s interested and I suggest that they request help from Gloria!

I locked myself out of my home. The gentleman called and advised me that he was ten minutes away. He was friendly & very professional. He verified my identification & address and then he quickly unlocked my door. I was very thankful since it was very cold & raining. The price was reasonable. I would definitely recommend this company to others. I hope I don't lock myself out of my home again, but if I do, they will be in my contacts!

A worker from another locksmith company left in the middle of the job and didn’t return. We had two holes in our doors to the house. Not good. We called ET Locksmith and Security. They said they would come in a few hours on the same day. The technician was amazing. He worked quickly and was very kind and patient. We had both locks replaced and they worked like a charm. I would recommend them without reservation.

Jonathon was amazing. We came in for a key that we had cut 3 times at different places and never worked. He explained to us what we needed and cut it quickly. It works and we are so happy we stopped in. It’s a cute small shop that does it all! Want your keys to actually work? Come here!

This place is in a convenient location for People that frequent the West Loop. I’ve been here several times & the customer service has always been great. I usually come on my lunch or break & i never spend more than 5 mins there. They were able to duplicate a key I couldn’t get copied at any of the major “hardware “ retailers.

We really appreciate the work performed by Non-stop Locksmith. The technician Gerardo was great and extremely detailed even in the harsh outside weather conditions. He answered all of our questions and made sure every lock and door operated properly before leaving the premises. Great Job! We'll definitely be using them again for any other projects in the future.

Alex was amazing!!! A situation where you need the help of a locksmith is not usually a stress-free one.... but Alex made it that way for me. His services have definitely made me feel confident to recommend Nonstop to my family and friends. Thanks, Alex!

Zach did a great job in our deadbolt lock problem. He's on time , efficient and was able to explain what are my options and what needs to be done. Would highly recommend Non-stop locksmith!

Office paralegal at Near Westside law office. I am very pleased and happy with the work and professionalism of Zack with Nonstop Locksmith. I would recommend him if you need any locks replace or repair. Will request him if the law office need any lock work. Thank again Zack.

CHICAGO (WLS) - There's a new reason to keep a close eye on your keys. The ABC7 I-Team tested new apps that make copies of keys without the owner's knowledge or permission. Two of the key cloning apps say the new technology doesn't make it any easier to steal keys. In fact, they say it leave an electronic trail. But some locksmiths have concerns. The I-Team shows you how easy it is for someone to get in your home with help from a smart phone. NONSTOP Locksmith featured in CBS News, on deadbolt Locks.
