Reviews frequently note quick turnaround for key cutting and car key programming, with several mentioning successful work on difficult or older keys. Many customers describe friendly front-desk help and clear communication. A smaller number of reviews raise concerns about workmanship details on vehicle interior trim after ignition or key work, suggesting care to confirm scope and expectations. Overall sentiment trends positive with emphasis on speed and in-stock solutions.

Best place to go and get a key made. We had a key that was 70 plus years old. No one could duplicate it. They had it. Five stars. The staff was very knowledgeable and friendly .

adriana gonzalez on Rex Lock & Safe

I paid them almost 400 dollars and they left all the garbage in my truck of the things they used to fix my key Ignition. They scraped all the door panel where and they didn't even close the case that sits on My steering wheel the clips don't close abs when I drive it hits the steering wheel. They made me new keys and fixed the problem but broke and Scrape parts that where fine before taking it to them. It was very unprofessional the way they left my truck especially after paying that much.

Needed new keys to my Accord badly. I had to strap a rubber band around my last key just to keep it together. This store cut and programmed a new key in under 10 minutes! They ordered a new remote for a second key and promptly followed up with me when it came in. Thanks for your experience and great service!

I used their services a few times and they did not disappoint. Very generous with their advice and not pushy at all I thought. They once held an info that could've saved me some money, but they put their own interests/profit before mine, it is a business after all. Overall, do your homework and they will help you with what you need. Great front desk service as well as most of their "technicians".

John Logsdon on Rex Lock & Safe

This place really helped me out. I needed to get another key for my car cut and the FOB programmed. They were very professional and got the job done pretty quickly.
I was a little nervous that the key fob that I brought in wouldn't work (because I bought it online) but I was fortunate that it did and they didn't have any problems doing what they needed to do.
If I need any more keys made I wouldn't hesitate to come here.
