Our Customers Say It Best

My particular issue was not something they were able to do, but they were extremely courteous and helpful in directing me to someone that could.

I needed replacement keys for a file cabinet. The Flying Locksmiths responded to my email within minutes, and my new keys were on their way within 24 hours.

Ben came to re-key a condo we purchased that didn't have a full set of keys. He was able to come early, finished quickly, was fair with pricing, and was friendly and professional.

Doug D.
First good sign was they answered the phone and communicated very well. They said they would be out the next day and they held true to their word. The tech showed up, changed all three locks and was out in an hour. No mess, no fuss and a great pricing. Thank you
John O.
Excellent service, on time to appointment, knowledgeable technician. Had an older Schlage decorative front door lock that would actuate. Technician knew exactly what was wrong with it and repaired it expertly. Highly recommend The Flying Locksmiths!

Arrived promptly, worked quickly and quite happy with the results. Plus Ben is a friendly and knowledgeable technician, it was pleasure to have him do the job.
Gerry G.
Nice folks on the online chat function, but not a physical location to get keys cut or get help. Don't be fooled by the local address. This is just a number to call to get a mobile truck to come for a service call.
Deborah S.
Great company showed up when they said they would and locks work great! Guys were professional and quick. I would highly recommend calling them for your locksmith needs!
Travis G.
I called them in the morning for a locked door and they were able to stop by early afternoon. Ben was really professional and the job was done in 15 minutes. I really appreciated their effort to accommodate our request in a timely manner.

Rosetta B.
I needed to change all of the locks on my home and wanted to install a smart lock to regulate access to my home when I am at work. I had no idea what equipment to buy or how to manage the whole upgrade. Flying Locksmiths sent a really helpful tech, who provided a no-cost consultation, figured out the simplest and most cost-effective way to proceed. He emailed smart lock recommendations with a variety of functionality and price points so that I could pick my preferred hardware. Once it arrived, he installed everything, re-keyed existing locks so I didn't have to replace them, and even fixed my front door so it closed better. He helped me to download the smart lock app and stuck around while I tested everything (it all worked flawlessly). The whole process - from the first phone call to the complete installation - took less than 2 weeks and the bulk of that time was me trying to decide which lock to buy. Also, the price for all of the work was extremely reasonable. Couldn't be happier. HIGHLY recommend this company.
Dianne B.
This group was the only group that would come out and help me get back into my house - I'd gone thru 10 locksmith calls before stumbling upon FL's. The gentleman who came to help was so nice and friendly. I would recommend them to anyone. They'll be the only locksmith I call in the future!
Lora L.
Received excellent service! My repair person was John. He knew his stuff and instead of telling me straight off that I needed to replace, he dug in deeper and repaired my lock. Real standup guy!
John M.
Great service! Locksmith arrived exactly when scheduled despite terrible weather and had no trouble quickly opening the lock.
Kevin W.
Came when they said, worked quickly and were pleasant.
Dawn G.
As difficult as the job was, they managed to handle all issue in a professional manner.
Rob N.
Great workmanship and a polite locksmith. Thank you for a great job.
William A.
Had them re-key locks to house. The technician did it quick and efficiently.
Brian did a great job and was very courteous. Thank You.
Johanna W.

Kevin S.
Great service with Attention to detail. Would recommend to friends.
