Contacted Diamond Locksmith on yelp using the "request a quote" program. Ray contacted me back with pricing for 2 new key fobs and programming. Accepted his offer and he gave me a time and date that worked with my schedule to do the work. Ray was punctual and showed up in the time period specified and started the work. He ran into a problem with my emergency key and was able to help fix that situation. In and out under 45 minutes. Diamond Locksmith (Ray)- Quick and efficient work. Great communication when a problem came up. Pricing was fantastic. Almost half of what a dealership was going to charge me for the same service. Will definitely call up again. read more

I would highly recommend using Diamond Locksmith for all of your needs! read more

Ray was very responsive. Though he came later than we discussed, he was quick in response and explained for his delay. His service was very quick too; it took less than 30 mins for the whole process. Price was also the lowest compared to other shops based on my search. in total, the car unlock service + transponder car key (no buttons) copy costed me just below $200. fyi, my car was Camry. Will I use it again? Yes. read more

Ray was able to give me a quote within about 10 minutes. He was cheaper than 4 other quotes I had received! $50.00 cheaper to be exact! And he was available with 20 minutes, came to my house, cut me a new key and fob on the spot within 10 minutes! Amazing service! I highly recommend this service and Ray could not have been more sweet and helpful. I am super grateful because with a broken key and fob, my car wouldn't remain on. It would start, then die, and a green key light would appear on my car. So thank goodness I got this fixed and found this business! read more

Diamond Locksmith - Keys & Locksmiths Near Me - San Mateo, California

These guys are AWESOME. We asked Vaughan at Diamond Locksmith to come change the locks in our new house, and to install a punch-code lock on our back door. There were a lot of special requests and some new hardware to buy, and Vaughan took care of it all. He was honest, friendly, fast, communicated clearly, and did exactly what he said he would do. We now feel safe in our new home, and we feel lucky to have had such a trustworthy guy help us out. HIGHLY recommend them. read more

You can trust Diamond!!!! Super professional!!! Very fast !!! Good price !!! And very friendly!!!! That's what I need. Thank you Diamond. read more

My battery died in my Mini Cooper and my door wouldn't unlock, with the fob OR the manual key. Diamond Locksmith answered the phone immediately, and dispatched someone within an hour. The dispatched person also called to let me know they were on the way. Got my door unlocked and discovered my battery was dead and the connection was loose. Teishon kindly tightened the connection and also gave me a jump, above and beyond what was originally requested. All with my 3 yr old toddler climbing around my car and also embarrassingly poking Teishon in the butt while he was working on my car (sorry!!!). They take Venmo! Got a copy of the receipt via text from their Square app. So quick and convenient if you need a receipt to submit as an insurance reimbursement. read more

Diamond Locksmith - My 2 new keys va my old broken one - Keys & Locksmiths Near Me - San Mateo, California

Exceptional service! Fast response and ensured everything was in order after changes. Fair pricing. I'm a big fan of Diamond Locksmith! Thank you. read more

It is good to know that there is one automotive locksmith in San Mateo that will come to your car and make you a new key in an emergency. We called dealer and we called the other locksmith in SM and they told us they can make us a new key but we would have to find a tow service and bring in the car ourselves. That would have added at least another hour to or wait and cost another fee. Ray came by in a hour and made us a new key within a half hour. It cost $350 but it was well worth it! Once we find our keys, it will cost another $80 to program each key to the new code. read more

Jay was able to tell me in details what my options were when my only set of car keys were stolen! Many other places just gave a quote without explanations or options. Jay was on time and communicated well. If I ever need a locksmith again, Diamond Locksmith will be my 1st call! read more
