So glad I found Ray and Diamond Locksmith! I sent an inquiry on Yelp on Monday, got an immediate response, scheduled on Tuesday, and Teishone came out on Thursday to duplicate a key fob for my 2013 MINI Cooper S. The price was very reasonable, and everything was handled quickly and smoothly. Ray was responsive, professional, and easy to coordinate with. Teishone, who actually came out and duplicate the key was communicative. He called me with ETA, arrived during the pre-communicated window, super nice and courteous. He helped us test the key with lots of patience. A lot of places either do not service MINI Cooper keys or were not able to help, so this felt like such a gem of a find. Highly recommend. read more

Incredibly happy with the level of communication, professionalism, quality of work, and price. Will absolutely use them again for my future locksmith needs. Thank you to Teishon for the excellent work and Ray for the fantastic customer service! Our project involved replacing existing front door lock (standard keyed deadbolt) and a back door digital lock (keypad deadbolt). We found Diamond Locksmith through their response to our project request. It was one of only a few businesses that responded that would actually give me a quote online (and the only one that actually read the details of our project). Pricing wise they were $40-$140 cheaper than others that responded. This coupled with their exceptional reviews on Yelp made this a no brainer. Very happy with that decision! read more

Quick and timely. Justin was great and fast. Literally done in 15 mins and note, we lost the key to the bottom lock so I was amazed how fast the job took. Thank you! read more

Cancelled appointment twice with last minute notifications and never told us what the increment in price is before the work was done, I will not hire them again. Price for parts in truck is 2X the cost of parts at a home improvement store read more

I had a fantastic experience with Diamond Locksmith! The quality of their work is amazing, and the technician was both incredibly quick and very friendly. From start to finish, the entire service was smooth and stress-free. Plus, the price was very reasonable for such professional work. Highly recommended! read more

Don't trust this locksmith with door replacements. This incompetent locksmith will only lie to get your business, rip you off, and leave an ugly mess behind. I requested a like-for-like replacement of the exterior lock (Weslock Lexington 1400 series). Instead, Diamond Locksmith installed a cheap lock under $100, charged $570 in excessive labor, drilled a new hole to force it to fit, and covered the damage with an ugly metal plate. He refused to repaint unfinished areas. I'm now left with irreversible door damage and extra repainting costs. Completely unprofessional. Response: This locksmith is not only unprofessional but also dishonest. The door is wooden, not hollow metal. The lock is also not unique or discontinued--an exact replacement can be easily found with a simple Google search. read more

I had a great experience using Diamond Locksmith. I needed to program 2 new key fobs. Their Yelp responses were quick, they called and showed up in a timely manner, they ensured their work was complete to satisfaction and they completed the work fast and efficiently. HIGHLY recommended. read more

I had to get my 2024 Honda Civic reprogrammed after an attempted burglary, and I'm so glad I found Diamond Locksmith. The price was more than fair, especially for two sets of keys, honestly the cheapest option I found on Yelp. Tishone was extremely professional and kind from start to finish. He kept me updated when he was on his way and again when he was nearby, which I really appreciated. He also took the time to explain the entire reprogramming process, so I knew exactly what was being done. The service was quick, smooth, and stress-free. Highly recommend this place & Tishone if you need key programming or car reprogramming--great service at a great price! read more

Car key programming for my Toyota Corolla became more complicated than expected but Teishone was able to troubleshoot and get the job done! Communication was efficient and they were able to do same day for me. Professional job done and for a good price. Thanks Teishone! read more

Had 2 key fobs programmed for 2017 Ford Explorer...also needed to have 2 "lost" key fobs to my explorer deprogrammed. Had both taken care of for the flat rate that was quoted with no games (all other quotes on yelp were $50 more). Tishone was great ! Would definitely use Diamond Locksmith again read more

They gave me the best price and showed up on time, lost key was cut and program in less than 10 minutes

Urgently needed to have my lock changed for my mailbox. They responded and came to change the lock same day. Provided new lock, keys, and everything at very fair price. Very professional, responsive, and got the job done. Great service, really no complaints. 10/10 would use again. read more

Great service and technician. Took the time went the extra mile on my finicky old E46 M3. In the end, new key programmed and the troubleshooting from Diamond led me straight to the problem. Couple fuses later and I have full functionality. Thank you! read more

Teishon was super nice & the service was quick, effective, and efficient! I was really anxious about losing my storage unit key and getting a lock cut, but felt super relieved that he was so professional and kind! 10/10 would recommend Diamond Locksmith! read more

Justin is very kind, clean and friendly. He did a great job changing out my locks and came fully prepared with what I called in and asked for, My locks are old and my neighbors are pretty shady, so it feel nice to have new set of locks up! read more

Great service, on time, called ahead. Adjusted my lock for a reasonable price, less than others! Didn't need a costly replacement.

I broke my 2022 Bolt EUV Car FOB by trying to change the battery. So l ordered 2 New Car FOBs from Amazon. Chevrolet wanted to charge $ 500 to Re Sync 2 FOBs. I made an appointment with Teishone, Technician/Diamond Locksmith. He came at 10 am, Explain in layman's terms what he going to Do. He Explained how to work the Key to get in the Door Knob and show me twice and let me try the process. The cost was quoted was the very Reasonable about 1/2 of Chevy Dealership quote. l am very pleased and will refer Teishone to All my friends. Food Sage/ Darryl read more

I needed someone same day. They made it work awesome Guy thank you so much for the key programming even after programming he let me see the codes left on the car since I didn't know what the codes I had on my car were for. Cut key add on was cheap that I couldn't skip out on it did it for my BMW most people quoted 15-20% more dealer wanted 2.8x the price read more

Very quick service and was able to arrange over text. Deshaun came out on the day I had requested in a timely fashion. Easy peasy!

The Diamond lock people were very helpful and conscientious. Completed the job as promised. Happy to recommend.

These guys are great. Quick to respond. Teishon showed up on time, was knowledgeable, professional and answered all the questions I had. Highly recommend. read more

Completely unprofessional and horrible customer experience. I have been in contact with this company for over two weeks trying to schedule an appointment to program a BMW key. Despite reasonable price quoted, the company has loosely scheduled "appointments" with me three times and has either no showed, ghosted, or rescheduled after having me wait several hours. On Monday I was told they would come in "the afternoon". I called around 3 pm and was assured they hadn't "forgotten" and that I was next. At 7 pm was told the tech was still working on another car and they could come the next day from 5-7 pm and was assured by the owner he would be working too... so it would get done. They never came or even had the decency to let me know the would not show up (even with me following up with them to ask for an ETA). If you are stranded with no keys - this is absolutely an unreliable company. Do not use. read more

Justin was quick, professional, and kind when changing the locks to my new place. I am happy with the service with how much I paid as well. I definitely recommend! read more

Fast and easy communication, they come to my house and make a new fob to my truck. high recommend,

On time and reasonable price. They were available quickly and got done within 10 mins to replace my barn door lock

Had Justin from Diamond Locksmith change a few locks around our home 6months ago. He was professional and transparent with pricing. Would use again. read more

Daniel was communicative about his arrival time and promptly updated 7 locks. He was knowledgeable and courteous. The price Ray quoted me was one of the better deals in the area for the number of locks updated. read more

This got the job done and was among the most inexpensive options after comparison. Thanks!

Response time was within 10 minutes for a lockout service. Got an ETA of 20-35 mins and DeSean came within 18 mins. Courteous and was direct on what needs to be done. The lock was a bit stubborn but he did not give up and stayed very calm. He explained what he was doing every step of the way and couldn't be happier with whom came out to help. Well worth the value quoted in the speed they were able to provide. Hopefully I don't have another issue again but they are the diamond in the rough! read more

Thank you Diamond! You really bailed me out. My son lost the keys to his car. Because he could not drive it, he let the battery run down. Since the remote door locks were dead, we were now locked out too! After arriving in town, I decided that I would have his car fixed. I asked for a bid through Yelp. Ray was one of the first to reply even though it was Sunday. His bid was better than most and wow, not as bad as I thought! And he came with a 5-Star Yelp review! So, I accepted Ray's bid and he was out the next day. Okay, first, we need to get into the car. Ray was in in just a few minutes. Now we need to jump the car so that we can program new keys. Ray went to work programming the fobs and the keys. In about 15 minutes, I had two new car keys. Since he was there, I asked if he would mage a couple of spare house keys. In one minute flat, I had my keys. That was the quickest key duplication that I've ever witnessed! Whew, it was all taken care of! I was worried I'd have to have the vehicle towed in to the dealer. What a life saver! Ray was responsive and able to do it all at a reasonable price! Everything I needed with one call. Definitely worth the call! Thank you Diamond! read more

Ray was very responsive and quick to reply. I setup an appointment with him to meet him at a site in Fremont to copy a car key. New key was laser cut and ready in 10 minutes. Easy and straightforward with no BS, very fair and reasonable prices. If you meet him at his location it's $45 while onsite is $100. I got a quote from some other place and it was $130 just to recut a key (wtf?). If you live in the bay area and ever need a locksmith, this should be your go-to guy. Thanks Ray! read more

Fast honest and kind. I appreciate the willingness to give an estimate online and the service was on time and quick. Very nice to work with. read more

Very easy to communicate with, and they were very detail oriented in the installation. Also left the work area quite clean. Much appreciated! read more

Easy. Flexible (my original appointment time had to change) and they were accommodating. Basic service request to reprogram 2 keys for our Camry. Teishone was on time, communicated well via text, professional and ensured all both remotes were working properly (test/retest) to ensure no problems. Service was quick and efficient and most importantly reasonably priced. Other businesses were quoting much, much higher. Appreciate the help! Will keep for future business. read more

I had a fabulous experience with Tishone and Ray. The came in and rekeyed my vehicles and house keys quickly and made sure that everything worked as expected and gave me a great deal. I would definitely recommend them anytime. read more

Fast quote , great communication and dedicated professional to do the work. I will definitely call Diamond Locksmith again.
