All the 5 star reviews are accurate. I had the unfortunate incident of getting robbed and they took my car keys along with everything else. I looked around for a locksmith to change the locks on my car and Ray was quick to respond with a quote and he came to me within the same day. HUGE peace of mind. Fast service. Super friendly. Highly recommend. Thanks Ray for helping us all feel safer! read more

Ray came out and was able to program a Mazda OEM key fob for me and cut a backup key in less than 20 minutes. His price was way more reasonable than what the dealership was going to charge me and he drove over to meet me. The fob and the key both work flawlessly and Ray's flat rate pricing made him an easy choice over the Mazda dealership. Worth every penny. read more

We received a prompt response to our enquiry. They showed up on time and finished job quickly. Fair pricing quoted on call and pricing didn't change on site. Highly recommend. read more

- Picked up the phone when I called.  (Which is reassuring, when you're locked out of the house, and in your pajamas in the cold.) - Came within 30-40 minutes. - Worked for 5 minutes on house door handle, and was able to solve the issue quickly. - It was cool to watch, as I know a tiiiiny bit about lock picking.  He did not rake, but used the proper tools.   - He was able to take a credit card through Square, and I received an email receipt Felt reliable and trustworthy, which is what you want when you're vulnerable and stranded.  The yelp reviews were correct.   Final comment: Would call again!  (If I am dumb enough to lock myself out again.)  Thanks! read more

They were great. We somehow completely lost our car key while camping in the middle of nowhere, up in the mountains above Half Moon Bay. This locksmith happily drove out in the middle of the night and made us a brand-new key with a functioning remote. It was less costly than I'd expected - at $300, that's about what I'd anticipate paying for the same service in town without the lengthy drive. The locksmith was courteous, friendly, and worked fast. He saved our vacation! read more

I lost a fob for my Toyota and Diamond came to my house and replaced it for half the cost of the dealer. OEM fob and great service.

Very communicable, reliable, and fast working. Showed me how the lock works and how to put it back together if I ever wanted to do it. Very impressed by how fast Ray was able to fix my lock problem. I have not used many locksmiths in the past, however I have 0 complains and nothing but 100 compliments. read more

Ray did an excellent job making a duplicate key for my vehicle. After meeting him for my appointment, there was an issue with making a key and he was unable to do so. Upon further research, Ray discovered a special key needed to be used which he did not have in stock. Ray ordered this key and we arranged an appointment the following week. Ray did not charge me for this special key that he had to order and still charged me the initial price that he had first quoted me. Ray was then able to make the key within 5 minutes. Ray provided excellent customer service. I will be using Ray in the future for any additional car key needs. read more

This is the second time calling Diamond. The first time we rekey one lock and Teishone provided great service. We called Diamond again as we planned a rekey project of all the exterior locks at our local church. Teishone stopped by and provided a free estimate. The estimate for the project was reasonable and fair. Teishone just finished up rekeying 19 locks. He was efficient and a pleasure to work with. read more

We had 2 different issues with 2 different doors in a new house. Ray came and was super nice. He showed us how we can fix it without him with simple attention to small details that are in those kind of old locks. I was so surprised that he didn't even charged me. Not even a dollar. I am pregnant and I'm also have a small baby at the house. He was very thoughtful and kind and professional. He came on time like we scheduled and finishes his work super fast and high quality. Thank you so much Ray. We're definitely recommending Diamonds locksmith. read more

Hired Diamond to flip our door lock. They offered the lowest quote and Ray was very responsive. Sean showed up early on the timeframe that we agreed upon. The job turned out to be more complicated than we thought, but they workshopped through it and got it done. Totally recommend! read more

Ray was amazing! Was able to program my e-bay purchased key on my 2002 landcruiser. Save me a ton of money vs. dealership . I highly recommend diamond locksmiths. read more

All I can say is WOW!! Excellent Service!!! My tenants called me that their front door lock broke. I called Diamond Locksmith and within an hour Marco was at the house. It wasn't a simple fix. He needed to purchase a deadbolt lock. The finish of the original lock was not necessarily common. Being the weekend I was concerned that a replacement might be challenging to find. Marco called a few hours later letting me know he found a replacement. He had gone back to the house, installed it and all was good, secure and working again. Marco was kind, thorough, efficient and very professional. My tenants are pleased and I am extremely grateful. Thank you Marco and Diamond Locksmith for your exceptional service. I highly recommend this company. read more

We had a door that stopped locking - older model sliding glass door and also needed to be rekeyed. DeShawn did an excellent job with this project, especially since it turned there was a broken wheel on the bottom of the door, so he pulled the whole thing out, fixed the wheel, cleaned it up and made it look easy. Pricing was reasonable and transparent. I would recommend Diamond Locksmith and DeShawn very highly! read more

Complicated project and Ray knew how to tackle the issue and get it done. Would recommend.

Ray is truly very professional. He drove 45 minutes to meet me at his shop, after I showed up without an appointment. He is extremely knowledgeable in all aspects of key lockers. He immediately understood what I need to replace with smart secure industrial grade key locks. He came to our new condo twice. First to inspect our existing 4 locks and propose specific locks to meet our security needs, including smart remote operations on iPhone. His second visit 3 days later, he came with all the new locks he ordered. On the spot he installed all 4 locks including 2 smart locks, all finished in one afternoon. He even cleaned up the mess at the end. Completely satisfied with his work. Highly recommend! read more

Ray was the first to respond to my need, and very accomodating when we threw a curve. Couldnt be nicer to work with. 5 stars.

Well, I sure wasn't expecting to get locked out of my home tonight with keys in hand! Our old (and apparently misaligned) door said it had enough, and wouldn't open, as I'd later find out, due to it being jammed. Diamond Locksmith responded immediately -- Marco let me know he would be here in 20 min to help out, and he showed up on time! And with a mask during these COVID times (thank you)! He helped me get back in, and fixed the root issue with the door. Really appreciated the kindness and professionalism. And while I'd hate to be in this situation again, I definitely know who I'm calling if I'm ever in a pinch. :) read more

Marco was efficient, professional, and friendly. He even took a chance and showed up early since he was in the neighborhood. Worked out well for me since I had so many projects to do that day. Check these guys out if you ever need this type of service! I highly recommend them. read more
