My daughter asked me this morning about getting a key fob added to her 2013 Hyundai Accent that has never had keyless entry. We emailed Onyx and they responded within two minutes. I talked with Aaron on the phone and within a half an hour a company van arrived at my home. Tyler was friendly and personable. Within ten minutes he had completed the programming of the fob and handed it to my smiling daughter. First rate service. I highly recommend Onyx Locksmith.

Lost our key fob at an amusement park, 3+ hrs away from the spare key. Tyler from Onyx showed up exactly when promised. He worked quickly and efficiently, and absolutely saved our day! Replaced our key fob, gave us a laugh. Awesome customer service. Absolutely recommend to EVERYONE in an area they service!!!

I called as I needed a new key and they came the same day and right to my house. I was not even home and they called me on the phone for payment. It was convenient and easy process. I would highly recommend using Onyx Locksmith.
