I lost the transponder for my remote key fob for my Honda, I called Diamond Locksmith and Ray showed up within a couple hours, cut the key and programmed it in less than 30 mins. He made it easy. Great service and a life saver. Thank you!!
Ori was simply outstanding. Front door lock was jammed and he carefully repaired it instead of replacing it, saving me money in the process. Polite, patient, and clearly an expert in his field. Exceptional locksmith service in San Francisco!
Needed a new key fob programmed and reached out to several locksmiths. These guys were one of the quickest to respond and the one of the most inexpensive. Very responsive and scheduled for the next day. Highly recommended. Teishon was great, thorough and fast.I was a little worried that the key fob I bought on Amazon would not work, but it did (be sure to check the number matches on the key you have with the one you buy).
The technician Teishone was on time and very professional. He explained the work he did and gave me options re getting new keys made. Thank you, so happy to have my lock fixed so quickly!
My one and only keyfob stopped working with my car and I was in pinch. Called up Diamond and Ray was able to come within a couple of hours. He was fast, friendly, and stuck with the job to get every detail 100% right. He gave the matter his full attention, and after making me a brand new key in addition to fixing my existing keys, presented a total bill that was very fair and a bit less than the quote he'd provided initially. I would not hesitate to call these guys again and would encourage you to consider for your locksmithing needs. Great job!
