Changed locks at my house after a bad renovation. Appreciate the service as they came out promptly. It was a good value As he charged us a nominal fee. A second visit was done as he didn't have the tumbler to do my front door. He ran out of time to change all the tumblers. I wasn't sure if he was going to charge me for coming back out but he did. Overall I'm glad he came out. read more

John is awesome. He is by far the most honest and affordable locksmith around. Never trying to upswell anyone, he's brutally (in a Very good way) honest when in comes to your locks and security. I've used him to key-alike our previous home, Grandfathers lake house, a firehouse, and most recently our new home. John often has spare re-claimed parts in stock to help repair what you have. He's a one-man show so he's not always in the shop when he's out handling a service call. His skills are trusted by several local municipalities, school districts, and townships. Look no further when you need a locksmith. read more

Five stars because it is a real place, unlike the other ones that pop up all over Google maps. I've been going here almost 30 years. John is getting a little cranky, perhaps because of all the business he has lost to these online scammers. He has always done a good job for me and he charges a fair price.

I went it to get a key made, I was informed I could not use a card for anything under $30. I told him I'd be right back I ran to Walgreens to get some cash and when i came back there was a sign on the door stating they wouldn't be back until 12pm. It was only 9:55! Rude I would never recommend! read more

After reading the positive reviews, I thought I'd call this guy to replace my deadbolt. I read that they've been there since the 70's...but apparently also STUCK in the 70's, because he suggested I take a photo of the lock and run it by the shop as it may be something he'd have to order. Well, can't I email the pic? No, he doesn't have e-mail...........Can I text it? No, he only has a land line phone. And they've been there since the 70's? well it's nearly 2020, and they don't have cellphones or email? They don't have me as a customer either. I called Goldy Locks instead. read more

This place has been in business since the early 1970's. I've never needed a locksmith before today. Im doing some work to my house and have a 120 year old front door that is 2 inches thick. None of the big box stores even knew of a lockset that would fit it. John at Certified not only knew what I was talking about, but was able to explain everything in detail and order all my parts for quick delivery. The price was even less than what I was expecting to pay. Any time I need a locksmith I'm hands down calling John at Certified. read more

Have to say I never thought I would hand out a review for a locksmith but if you live in Blue Island it most certainly the spot for keys to be made, the price was reasonable and they work every time, no return trips for a re-cut read more

I called about a non-working lock and one that wasn't working correctly. The one lock was replaced the other re-keyed. The knob had an issue which was addressed without my asking. Everything was done professionally and politely. Extra effort was put into the job which was greatly appreciated. Such a positive experience with a local merchant! read more
